Product Details


The Sinn 104 has become one of the best selling watches in the history of the company.

The Sinn 104 I St Sa White Dial maintains all that's great about the Sinn 104 Series, but takes on a completely different look with the white dial, day and date wheels.




This watch design takes Sinn back to its roots - a simple design without clutter and without gimmicks. Although this watch has design cues from chronograph watches, it is not a chronograph but rather a time, day, date and rotating bezel watch.

And to make things even more interesting the date display alternates between German and English.

Despite the aggressive pricing on this watch, Sinn has taken no shortcuts. The base movement is chronometer grade equivalent, sapphire crystals are used on both sides, and the look and finish of the case leave no doubt that it's a Sinn.

This pilot's watch features a highly legible white dial, and the watch is water resistant to 200 meters. The ratcheting bezel is of Sinn's design and will not snap off the case if hit due to its screwed bezel construction.

  • Case made of stainless steel, polished
  • Captive pilot's bezel with minute ratcheting
  • Sapphire crystal glass on both sides
  • Water resistant to 200 meters
  • English and German day display
  • Low pressure resistant
  • Sinn dark brown vintage calf leather strap

WatchBuys is the official and authorized North American distributor and importer for Sinn watches.

When you purchase your new Sinn watch from WatchBuys, you'll not only get a finely engineered timepiece with excellent value for money, you'll also benefit from the WatchBuys Sinn Advantage.


WatchBuys Advantage #1

Because we are the official and authorized North American Sinn distributor and importer, your name and watch serial number will be automatically registered in our database for a Sinn manufacturer's limited warranty which we pass through.

This means that should your watch require service during the Sinn manufacturer's limited warranty period, service will be provided by Sinn in Germany when you return your watch to them. This Sinn manufacturer's limited warranty is transferable to subsequent owners as allowed by Sinn.

You are responsible for paying the shipping charges to Sinn, and all repairs that Sinn approves under its warranty are at no charge. Sinn will also pay the return shipping charges to the address you specify.

The Sinn manufacturer's limited warranty period is as follows:
  • Watches in the EZM Series: 3 years
  • Watches marked AR containing inert gas: 3 years
  • Watches in the DIAPAL Series: 5 years
  • All other Sinn models: 2 years

WatchBuys Advantage #2

As an added benefit to those who purchase Sinn watches from WatchBuys, you may choose to have your warranty repairs serviced through our US Sinn Authorized Service Center, RGM Watch Service located in Mount Joy, Pennsylvania. This added benefit saves our clients the time and effort of returning their watches to Germany for repair. This service is transferable to subsequent owners who purchase directly from the original registered owner.

Please note that you are responsible for paying shipping and insurance charges for sending your watch to RGM. Once they reach your watch in the service queue they will determine which repairs are covered under Sinn's warranty.

It is important to note that oil-filled quartz Sinn watches must be repaired in Germany (EZM 2, Hydro and UX series). If your watch meets one of these conditions and requires service under warranty, please click here for instructions on returning your watch to Sinn in Germany.


WatchBuys Advantage #3

Your watch will be repaired at no cost to you other than shipping charges to either Sinn or RGM during the warranty period. Sinn watches purchased through the "grey market" (non-authorized sources) may carry no warranty from Sinn. Sinn watches purchased through authorized overseas retailers are governed by the warranty policies of those dealers and/or Sinn, and typically must be sent to either the overseas dealer or Germany for repair.


WatchBuys Advantage #4

You'll be wearing your new Sinn watch soon after your order is placed since we stock Sinn watches and ship free using UPS Air. Plus, since we are located in the United States, there are no "hidden charges" for shipments to US residents as is the case with most overseas dealers. Such charges can add up to 15% to the cost of your new watch, and include credit card surcharges, foreign exchange credit card bank fees, import duties and taxes, and custom's broker charges.


WatchBuys Advantage #5

WatchBuys offers a comprehensive return policy with no restocking fees to US residents. Overseas dealers, including those involved in the grey market, typically don't offer a return policy, and if they do, returning a watch under the policy is both complicated and expensive due to import/export and custom's requirements. Restocking fees are also common and may range up to 15%.

Learn more about our return policies.


WatchBuys Advantage #6

WatchBuys is pleased to accept payments through PayPal, debit and credit cards. We charge no surcharges to use credit or debit cards, and because we are based in the United States your US card is charged in US dollars with no conversion or exchange rate fees.

We also accept payments from PayPal and charge no surcharges.

Please note that to pay by credit card, debit card or PayPal your account and/or card must be issued by US or Canadian financial institution and billed to a confirmed US or Canadian address.


WatchBuys Advantage #7

When you purchase your new Sinn watch from WatchBuys, you'll earn WatchPoint Rewards which accumulate and may be redeemed against future purchases.




Sinn watches feature a number of cutting edge technologies, many of which are unique to Sinn. Please note that not all Sinn watches, including the watch on this page, use all of these Sinn technologies.

Among the more notable Sinn technologies are:


Tegimented Hardened Cases

Many Sinn watches are fitted with Tegimented cases produced in-house by Sinn's case making affiliated company in Glashutte, Germany.

Standard steel used by most watch companies has a hardness of between 200 and 240 HV (Hardness Vickers is a common scale used to measure material hardness). The Tegiment process produces a hardness of at least 1,200 Vickers which is five times harder than standard steel (and on some Sinn models up to nine times harder than standard steel).

The Tegiment process is not a coating consisting of a foreign material; instead the steel itself that has been hardened using a special engineering process that creates a hardened barrier. The base material is a type of stainless steel also used for surgical implants, and the stainless steel resistance to corrosion is further improved by the Tegiment hardening process.

The primary advantages to a Tegimented case are extreme resistance to scratches and other case abrasions, as well as increased resistance to corrosion.

Please note that certain Sinn watches are fully Tegimented (case, bezel) while others are Tegimented only on the bezel. Use the links below to view both categories.

  • View Sinn watches with fully Tegimented cases.

  • View Sinn watches with Tegimented bezels only.


Dehumidification Technology

A number of Sinn models feature cases filled with inert gas. Sinn has found that filling the case with inert gas can help prevent the introduction of moisture and humidity to the case, as well as provide a more stable environment for the oils that lubricate the movement.

The proper care of any mechanical watch movement mandates that these oils maintain both their viscosity and lubrication properties.

  • View Sinn watches with dehumidification technology.


Copper Sulphate Capsules

A number Sinn models use one or more copper sulphate capsules to absorb humidity trapped inside the case. Over time these capsules will gradually turn dark blue indicating that humidity has been absorbed.

The primary benefit to these copper sulphate capsules is a more dry and stable environment for both the movement and the lubricating oils. Together with Sinn's inert gas treatment these capsules form the basis of Sinn's Dry Hold Technology.

This technology not only provides a more stable environment for the movement, but also prevents fogging of the crystal when going from hot to cold environments or from humid to non-humid conditions (such air conditioned buildings).

  • View Sinn watches with copper sulphate capsules.


Extreme Antimagnetic Protection

Magnetism can cause dramatic swings in the timekeeping of a mechanical watch movement. People are often exposed to magnetic fields without even being aware - frequent high altitude flying, metal detectors, audio and video equipment, medical equipment and computer equipment can all cause problems with magnetism.

Many Sinn watches offer extreme protection against magnetism up to 80,000 A/m. Sinn achieves these results using a number of different technologies, including special case and case back construction, soft iron components in the case and protective rings surrounding the movement.

  • View Sinn watches with extreme antimagnetic protection.


DIAPAL Oil Free Escapement

Sinn caused quite a stir when they first released their DIAPAL technology. Beginning in 1995, Sinn began work to create an oil free escapement. With any mechanical watch movement, the aging of oil, especially in the escapement can create long term problems for that movement. Additionally, as movement oil ages, required service intervals become more frequent.

Sinn's early analysis to this problem provided a quick solution (at least in theory) - if you don't use oil, it can't age. The process began by exchanging the ruby escapements for diamonds (the word "DIAPAL" derives from the German name for diamond escapements) in order to achieve the desired effect. The designation stuck, even though today Sinn works with solutions taken from advanced nanotechnology rather than diamonds.

The result is a movement that proves so reliable that Sinn offers an unprecedented five year warranty on their DIAPAL watches.

  • View Sinn watches featuring the DIAPAL oil free escapement.


Hydro Oil Filled Technology

Sinn has developed a technology termed "Hydro" in which the entire watch case is filled with oil. Watches using this technology are based on quartz rather than mechanical movements.

By using this type of movement, Sinn is able to fill the watch with oil, which has the joint affect of greatly enhancing the readability of the dial and time from any angle (including under water), and increasing the water resistance of the watch even at great depths.

  • View Sinn watches with Hydro Oil Filled technology.


Submarine Steel

Sinn has created a line of watches featuring cases made from German submarine steel (the U Series). The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany's North Sea shipbuilding yards who construct submarines from the very same steel.

Because of the special steel used from the submarine steelmanufacturer, the case resists the effects of exposure to salt waterand salt water environments.

These cases are produced in-house by Sinn's case making affiliated company in Glashutte, Germany.

This special steel is also amagnetic which means that is does not have magnetic properties and cannot itself become magnetized. The watch movement itself is protected from magnetic fields up to 4,800 A/m.

  • View Sinn watches built from German submarine steel.



EZM Mission Timers

Sinn is a partner for manufacturing watches for the German Special Forces, including SWAT, Customs, FBI, helicopter police, GSG9 and other units.

Beginning with the now highly collectible (and valuable) Sinn EZM 1, Sinn has grown this collection to some of the most durable and highly functional watches made and they remain among the most popular in the collection.

SO good!

"SO good!"

Verified Watch Owner Comments: I love this watch! I have a small wrist (6 1/4in) so this is really a good size for you thin wristed folks. It is good as all the reviews, all the youtube videos say. The leather band is great also! I did have to punch an extra hole though. I really love the count down bi directional bezel. I use it all the time.

This is accurate also! so far I'm getting around 1-2 seconds fast per day! Honestly when I saw Watchbuys' website, I was skeptical. But I noticed that they were very active in their communication throughout the entire process in a very good way. They work with you. I was also very pleased that the watch came with the correct time!

That kind of detail does mean a lot in this day and age. I would highly recommend the watch and this company! Matter of fact I'm eyeing more German watches in this site!

The clean white face drew me in

"The clean white face drew me in"

Verified Watch Owner Comments: I was looking for another black faced Sinn (836 never available) - but I kept seeing this 104 in white it eventually won me over.

Lil sis 104, big bro 836. Ask me in 8-10 years if I still love it.

Perfect Service

"Perfect Service"

Verified Watch Owner Comments: Sinn 104 I St Sa White . Before watch shipped, WatchBuys calls and verifies order. Watch arrives on time, running and set to the correct time to my time zone and correct date.

WatchBuys calls again to make sure that every thing is correct and that I am satisfied. Superb service and follow through on the sale. My next watch will be from this store. Probably a Blue 104.

Just a stunning watch

"Just a stunning watch"

Verified Watch Owner Comments: This purchase was my first foray into non-micro brand watches, and it does not disappoint. Stunning in appearance, it hasn't left my wrist since I purchased it - and I expect my other watches will get pretty dusty.

Customer service is top notch as well. After I made my purchase on-line, I received a phonecall from Watchbuys confirming my purchase, explaining the return policy, and answering any and all of my questions. A fantastic experience all the way around!

Opinion on watchbuys

"Opinion on watchbuys"

Verified Watch Owner Comments: Great experience!!! Fast, great service, and transparent. I appreciate their rep calls you to inform you they received payment and they are ready to ship.

Watch came as expected and I’m loving it. Will definitely reconfirmed them and I will buy again from them…first I need to start saving!!, lol! Manuel

Excellent Craftsmanship

"Excellent Craftsmanship"

Verified Watch Owner Comments: I could not be happier with my Sinn 104. The build quality is exceptional and the style is eye-catching. I get comments about this watch pretty much everywhere I go. If you are on the fence about whether to go for this one, I can't recommend it highly enough!

The 104 is perfect first automatik

"The 104 is perfect first automatik"

Verified Watch Owner Comments: I looked at many brands of mechanical watches over the last couple years and kept coming back to this Sinn 104 in white. I really just wanted a solid automatic (my first) and this white dialed version did it for me.

I work remotely for a German company and I asked a coworker (a watch nut) what he thought a good brand was. With no hesitation he said Sinn. Glad I followed his advice. I only wish it didn't take me two years to decide.. haha!

Deserving of its reputation

"Deserving of its reputation"

Verified Watch Owner Comments: The Sinn 104 series enjoys an excellent reputation in the watch community and after having finally receiving one from Watchbuys,

I now understand why. Three things stand out:

1. It fits a wide variety of wrists due to its compact size and low overall weight
2. It has a unique blend of a crisply-printed dial, entirely-polished case finish, and potent C3 Super-LumiNova lume and
3. Its design is technically one of a pilot watch but the unusual rotating countdown bezel and day/date complication provides an overall utility that makes this watch very versatile in everyday use.

The white dial variant I have looks great on virtually every strap I mount it on, from colorful NATOs to leather to perlon straps.

Sinn 104 White Dial

"Sinn 104 White Dial"

Verified Watch Owner Comments: I had heard this company had a good reputation which is why I went with them.

Customer service was superior and a call was made to me to confirm order and nail down an exact shipping / arrival date - sometimes a nosey wife can ruin the new watch experience, lol.

The watch arrived on the expected date. It was a great day, packaged perfectly and well protected. Perfect condition as I expected. A stunner which I doubt will ever leave my collection.

Will definitely buy here again. Thank you and highly recommend.

Sinn 104 I St Sa White on Strap

"Sinn 104 I St Sa White on Strap"

Verified Watch Owner Comments: I've this this Sinn 104 I St Sa White on Strap for 2 weeks, So love It for daily wear The watch has vintage, crystal & sporty look

Classic tool watch

"Classic tool watch"

Verified Watch Owner Comments: This is a great, versatile watch. The white dial makes it a true strap monster. It's a good size and thickness, even for smaller wrists. The polished case means you can even get it to work at the office, with the right strap. Do NOT expect luxury-level finishing and assembly (i.e. Alignment, printing, etc) . This is still a tool/instrument. A tough watch that happens to be great-looking.

Sinn 104 I St Sa White

"Sinn 104 I St Sa White"

Verified Watch Owner Comments: Love this watch. Sits well on the wrist and the dial is incredibly legible in all types of light.

The Watch Buys customer support was fantastic. The watch came in on time and I had no issues whatsoever.

Great Daily

"Great Daily"

Verified Watch Owner Comments: This is my 2nd Sinn and I’ve been wearing if for about 2 weeks. Its a strap monster, looking good on natos, leather and dive straps. Extremely versatile piece and not so expensive that I’m not concerned swimming, take out hiking ect. The leather band is nice, but rather large so I will have to put in an extra hole. I think I should have bought the H-Link bracelet option as I will probably wind up getting it at some point.

Classic in the Making

"Classic in the Making"

Verified Watch Owner Comments: This will be the vintage watch we all want and remember in 10-20 years, the white dial will age so beautifully with a timeless style. I was torn colors but their a reason these are in higher demand, such a clean look. Put it on a medium brown rustic strap and you may never change straps again.

Shout out to their communication and shipping, all aces.

Sinn 104 from WatchBuys

"Sinn 104 from WatchBuys"

Verified Watch Owner Comments: I have been eyeing the Sinn 104 I St Sa White for some time and now that it is on my wrist, I could not be happier. The 41mm size, downsloping lugs, and low case height ensure that it wears great. It is versatile working as a tool watch as well as dressing up for the office. The dial is a beautiful design with sub-second markers giving you precise readings from the syringe hands.

Great experience buying for WatchBuys. I placed the order on a Sunday. As this was my first purchase from them, they called me on Monday to confirm the details. The watch was in my hands on Wednesday, nicely packaged and in perfect condition.

First Sinn won't be last

"First Sinn won't be last"

Verified Watch Owner Comments: My first Sinn. Impressed with craftsmanship, build quality, fit and finish. Would certainly consider another Sinn model.

Sinn 104

"Sinn 104"

Verified Watch Owner Comments: Got this watch for Christmas 2018. First six months, watch was quartz like accurate. Now, about 9 seconds slow per day. My white dial came with the dark brown leather strap. The leather on the inside of the keepers separated, Watchbuys replaced the strap quickly and without hassle.

I wanted to replace the strap with the light brown strap that comes with the green dial. Watchbuys would not do that. I offered to pay any difference, I was told no. They replaced what I bought without hassle, but I feel the change in straps could have been accommodated. The day and date sometimes does not change until 0730. One time the day changed to the German spelling. I thought the accuracy would be better.

Great everyday watch

"Great everyday watch"

Verified Watch Owner Comments: I can’t say enough about this watch. It is the perfect everyday watch. The 41mm size makes it ideal to wear daily. It sits very comfortably on your wrist. There are tons of strap options for this watch. Great quality and craftsmanship for the price. I would highly recommend.

OK so far.

"OK so far."

Verified Watch Owner Comments: So far watch is fine.

Wow

"Wow"

Verified Watch Owner Comments: My 104 came in perfect order. The watch was flawless the service sublime The 104 was regulated to under +2 seconds a day after two weeks. Better than my one year old submariner Money very well spent

Amazing watch...

"Amazing watch..."

Verified Watch Owner Comments: I have been eye balling the white 104 for months and finally decided to pull the trigger. Ever since it came in I have been obsessed with it. Really a 1 watch collection.

Great watch!

"Great watch!"

Verified Watch Owner Comments: I have had this watch for almost a month and it has exceeded expectations. It's perfect in design and customer service from Watchbuys was top notch. I'm not keen about the black dial version but the white dial is exquisite and I love looking at it.

Great watch

"Great watch"

Verified Watch Owner Comments: This is my first Sinn and the quality of the watch is fantastic. I can't seem to take it off to rotate with any other watch. It is very practical and works in any occasion, the design is universal. The bracelet is a bit on expensive side so I went with a strap.

WatchBuys transaction was professional and fast, no complains.

Amazing! go ahead and buy one.

"Amazing! go ahead and buy one."

Verified Watch Owner Comments: Great watch. i purchased because, well, one its sexy, and two for the countdown bezel. i use the bezel every day at work for various things (Im in manufacturing and time is everything) for what im doing the countdown is better than the count up of a diver. The strap is really nice too. Mine rocks various NATO's cuz thats just the way i am but the leather strap is top notch.

I really cant say enough good about this item and about Watchbuys. i will be using this supplier again (got my eye on the 556 next hehe)

Fantastic watch

"Fantastic watch"

Verified Watch Owner Comments:

I’ve had this watch for almost two weeks and it has not left my wrist. The quality rivals many luxury watches. Absolutely stunning dial. Love the bidirectional bezel. Leather strap is of great quality. Money very well spent.

Also great customer service which made the experience even better.

Loving my Sinn

"Loving my Sinn"

Verified Watch Owner Comments: I researched for weeks on my first watch purchase over $150, and couldn't be happier with the Sinn 104. Currently wearing it with a black silicone strap which is perfect for the summer. The stock brown leather strap seems to be high quality but will need some time to break in.

All in all a perfect every day watch and WatchBuys was great to work with!

Fantastic timepiece!

"Fantastic timepiece!"

Verified Watch Owner Comments: The Sinn 104 is incredible value for money with a build quality and finishing that is very high level for the price point. Watchbuys was very thorough and easy to deal with.

SINN 104

"SINN 104"

Verified Watch Owner Comments: First off, I want to personally thank the various customer representatives for the excellent service and information provided throughout the watch buying process.

Bravo!

The watch itself is beautiful. It is extremely versatile and can be used while being either dressed up or dressed down. 41 mm is the perfect size for me . The white dial is extremely legible and the lume is outstanding. If I had any complaints, it would be with the strap. I opted for the Cowhide Black / White Stitch - Alligator Grain (SI-943) strap and, to be honest, I was not impressed. The buckle /tang appear to be a bit flimsy and the strap itself a bit uncomfortable. Apparently my wrist size is such so that the watch is either much too tight or too loose. I may eventually look into an aftermarket strap.

Sinn perfection

"Sinn perfection"

Verified Watch Owner Comments: An absolute stunner. Elegant size and finish. My new favorite in my 15 watch collection.

Excellent All-Purpose Watch

"Excellent All-Purpose Watch"

Verified Watch Owner Comments: I have worn the Sinn 104 (white dial) for 2 weeks. The craftsmanship of this watch is first-rate. The white dial is beautiful. Everything pops. I appreciate the simplicity of the design. The dial is exceedingly legible. I wondered if is 41mm size might be too large for my 6.5 in. wrist, but this Sinn 104 is a perfect fit. There are a ton of straps that look great on this watch. The dark brown leather strap it comes with is high-quality, very thick, and takes a couple weeks to break in. Sinn nailed the overall aesthetic for this watch. It can adapt well to work, play, and formal occasions. The high quality and style exceeds most watch brands I researched at this price point. Sinn doesn't take any shortcuts with the design and manufacturing. I feel that this watch delivers a lot of quality for price. Beyond that, the customer service from Watchbuys was first rate. Shipping was very fast. Two representatives reached out to me to ensure customer satisfaction. I would not hesitate buy... - more details
