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 if you are brushing up on your German language skills.

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


This watch is fitted with a Sinn stainless steel H-Link bracelet with locking clasp (not quick adjust).

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.

Best all round watch for the money

"Best all round watch for the money"

Verified Owner Comments: Can’t say enough about Watchbuys customer service. Patient and well informed people that are readily available to answer any questions. Rob guided me through the process and actually owned a version of the watch I purchased so his knowledge was first hand. The watch itself is a great GADA. Top level movement which makes a difference beyond just good regulation. Having a day function is convenient. Real sight dome to the sapphire which is just really nice and a flat sapphire display back that fits my boney 6 7/8 inch wrist perfectly without flopping around. Initially I worried it would be big but it’s just perfect. White dial is easy to read and gets a lot of compliments. Also the lume is good in that I can see it all through the night. It might not be a great analogy but, if you loved the skx007 but wanted it flatter and just better and higher end version on every level with 0 QC issues, this is it. Don’t get me wrong, this has it’s own character entirely, I’m only referring to fun... - more details

My First Sinn, not the last

"My First Sinn, not the last"

Verified Owner Comments: I bought my first Sinn, a 104 white dial with h link from Watchbuys. It feels and looks so great on my 6.5 inch wrist. The watch is super accurate and became my daily watch. It’s casual, dressy, tactical all at the same time.

I was also impressed at Watchbuys customer service as they were available and knowledgeable answering all my questions.

The best color for one of the best daily wearers!

"The best color for one of the best daily wearers!"

Verified Owner Comments: This is not the first Sinn 104 I have purchased from Watchbuys - I've owned a number of the colorways. However, the white dial to me is the ultimate look for this watch.

As always, the service from Watchbuys was top notch. Highly recommend this watch and Watchbuys!

It's everything I wanted it to be

"It's everything I wanted it to be"

Verified Owner Comments: I've had my eyes on this watch for years because to me it looks as close to visual perfection as one is going to get. The accuracy out of the box is much better than I expected. Everything is perfectly aligned.

I'm generally not a big fan of logos, but the black Sinn wordmark against the pure white looks amazingly classy and elegant, as does the watch in general. I'm also a big fan of the unique H-link bracelet, which wears very comfortably. However I do wish the clasp had push buttons to open it.

All in all it's easily the favorite of my otherwise humble collection, and I'm happy to wear it almost daily.

Great Entry Level Luxury Watch

"Great Entry Level Luxury Watch"

Verified Owner Comments: This is not my first Automatic Watch, but it is my first Automatic that costs over $300. I was considering a more expensive watch from a well known Swiss maker that was actually 3 times more expensive. I'm glad I went with the SINN! The quality of this watch is exceptional, the bezel lines up perfectly, love the fact its bi directional. The watch is beautiful and the white dial gets a lot of comments. This is my first German made watch, although it does have a swiss movement. The only complaint is I wish the bracelet was a bit more adjustable, maybe even an addition of a sliding micro adjustment similar to Omega or Rolex. Overall its a great value for the money. I like the allen head screws that are holding the links together in the bracelet, it makes removing links very easy and they send the tools required as well. Watchbuys contacted me to see if there was anything I needed before the watch shipped, and to ensure the order was correct before it mailed out. They also included a... - more details

Sinn 104 I St Sa White on H-Link Bracelet

"Sinn 104 I St Sa White on H-Link Bracelet"

Verified Owner Comments: I was so excited to get this watch. I had my eye on it for quite awhile. I looked at reviews did the research and finally pulled the trigger. So happy with this purchase.

The white dial with the black accents just pops out and like my 556i it is very versatile to wear. I opted to purchase it with the H-link Bracelet which to me is very appealing. I also bought some vintage leather straps so when the cold winter months come I can change it out.

Time keeping is very accurate. I've had this a couple of weeks now and the time is still true.

The customer service was very good and the packaging was again handled with care. 5 stars all around. Highly recommend getting this watch, you will not regret it.

Outstanding quality

"Outstanding quality"

Verified Owner Comments: I purchased this for my wife and she absolutely loves it. She wanted a rugged, tough watch with easy readability and the Sinn 104 was the clear choice.

This is my third Sinn and they all function perfectly!

One of the Best for Daily Wear!

"One of the Best for Daily Wear!"

Verified Owner Comments: I have now purchased multiple models of the Sinn 104 in multiple colors from Watchbuys.

As always, the watch is amazing, as well as the service. Truly one of the best watches for daily wear - highly recommend!

Great transaction

Beautiful watch for a reasonable price

"Beautiful watch for a reasonable price"

Verified Owner Comments: All positive to say except one thing: the clasp. Sinn could do a better job on the stamped metal clasp. That said, I love the watch and am really happy with the purchase.

Sinn 104 White dial with H bracelet

"Sinn 104 White dial with H bracelet"

Verified Owner Comments: All the other reviews are correct that this is a beautiful piece. It's every bit as nice as my Rolex Submariner and the white dial is a fun contrast. I see a lot of submariners around but not many of these. It has its own look and a design that says I'm not a Rolex me too. The metal bracelet is not as comfortable as the Rolex oyster. It will catch a few hairs on your wrist. I had an issue with the stamped clasp which had sharp inside edges. They were sharp enough to cut into my wrist when pushing down to close the link. Watchbuys did not hesitate to replace this part and immediately send a temporary clasp by Fed X. They also said a new part would be ordered from Germany. The temporary clasp does not have the sharp edges so this should not be a concerning issue. Great customer service with Watchbuys. I'm wearing the watch on the leather strap now. The straps are very thick and would benefit from some tapering. Over time the stiffness should improve. The leather strap is lighter an... - more details

Great watch and service

Verified Owner Comments: I love the watch! It was very easy to adjust the sizing, setting was easy and the WatchBuys experience was great. If I ever decide to replace this watch, I’ll definitely shop at WatchBuys again.

Sinn 104 St Sa White Dial

"Sinn 104 St Sa White Dial"

Verified Owner Comments: I love this watch. I have no complaints about it at the moment, after wearing it almost every day for 3 weeks. It's a great size for my 6.5 wrist and I love the glossy white dial.

Customer Service was great and thorough.

My Favorite Sinn

"My Favorite Sinn"

Verified Owner Comments: The Sinn 104 is a phenomenal everyday watch - this is no secret. I've owned the black dial before, but this white dial takes it to another level. It somehow makes it even more versatile on a variety of straps and gives it that extra little bit of differentiation I was craving.

Absolutely love the piece and the service was top notch as always from Watchbuys!

Sinn 104W on H-Link

"Sinn 104W on H-Link"

Verified Owner Comments: This Sinn 104 is a fantastic piece. At 41mm it fits my 7.5'' sized wrist quite well. I was glad that I went with the bracelet. The bracelet is well built even if the clasp leaves a bit to be desired. Sinn watches are priced fairly for what you get.

Watchbuys was great to deal with. Good communication and quick shipping. I wouldn't hesitate to buy from Watchbuys again!

Sinn 104 w review

"Sinn 104 w review"

Verified Owner Comments: It's a great watch that i'll own for years. If you're hesitating buying this watch then just get it. The white looks more classy and looks great with the black contrasting bezel.

Watchbuys is a great service and would recommend 100%

Sinn 104 White on H-Link

"Sinn 104 White on H-Link"

Verified Owner Comments: Just got this watch a few weeks ago and I love it. The finishing and attention to details is exceptional and on par with watches that cost significantly more. I highly recommend this watch.

I'm glad I bought this on the H-Link bracelet. It's very comfortable and looks great. The clasp isn't the best out there, but it is solid and well built. It's worth the extra money over the strap if you're a bracelet guy/girl. That being said, this watch will look great and a ton of different straps.

Watchbuys was great to deal with. They shipped it right away, contacted me to go over a few details, and I got the watch the next day.

104 watch superstar

Verified Owner Comments: I have had this watch for about two weeks now and I am more than pleased. The craftsmanship is superb. The time keeping is spot on. Very comfortable to wear. This is my perfect daily watch.

Beautiful Sinn 104 White

"Beautiful Sinn 104 White"

Verified Owner Comments: I already had a Sinn 104 with the black dial so I knew what I was getting. I like them both but find the white dial a bit more distinctive and different. The size for me is perfect because my wrist is on the thin side. At 41mm that's about as large as I go but because this watch is not too thick it wears well on a smaller wrist and under a shirt cuff. I love the clean dial and fine markers.

It's also a great value within the Sinn lineup. Highly recommended.

Great watch and great transaction

"Great watch and great transaction"

Verified Owner Comments: The buying experience from WatchBuys was fantastic. I received a personal email when the watch became available. And it was just my luck I only had to wait a few days.

The customer service was so helpful as I could tell I was emailing with an actual employee, not an off-shore support service. I received the watch very quickly. Within 2-3 business days of purchase I believe. And the watch itself is amazing. The Sinn 104 (white dial) is a wonderful addition to my collection.

I would most certainly buy again from WatchBuys. Thanks guys! Colin
