Sinn 104 I St Sa on Strap
Sinn 104 I St Sa on Strap
Product Details

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 matte black 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.

This watch has become a true Sinn classic in a very short amount of time.


  • 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


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, 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 service center, RGM Watch Service located in Pennsylvania. This added service saves our clients the time and effort of returning their watches to Germany for repair. This benefit 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.

Please also 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 contact us and we'll provide instructions for shipping the 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 FedEx. 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. Among the more popular features 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 layer has a hardness of 1,200 Vickers which is five times harder than standard steel (and on some Sinn models even higher - up to nine times harder than standard steel).

The Tegiment layer 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 even further improved by the Tegiment hardening process.

The primary advantage to a Tegimented case is extreme resistance to scratches and other case abrasions.

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 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.

Another advantage to this technology is that it prevents the dial and crystal from fogging. 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 knowing so – frequent high altitude flying, metal detectors, audio and video equipment, medical equipment and computer equipment to name a few.

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, "Diamantpaletten”) 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.

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, and each movement is a certified chronometer.

By using this type of movement, Sinn is able to fill the watch with oil, which has the double 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.

  • View Sinn watches in the EZM Series.



TESTAF Certified Pilot's Watches

Lothar Schmidt, Sinn's CEO and owner had long been disturbed by a lack of technical standards for defining a "pilot's watch". As an engineer, Mr. Schmidt was fluent in standards for diver's watches, anti-magnetic watches and the many other technological standards used to manufacture watches.

A widely used reference for standards is DIN, or the Deutsches Institut fr Normung (German Institute for Standardization). Oddly, he discovered there were no DIN standards to cover pilot's watches where such standards exist for example for diver's watches.

The new "Technical Standard for Pilot's Watches" (TESTAF) was developed by the Aachen University of Applied Sciences and establishes the suitability for professional use as a pilot's watch.

Sinn 104 St Sa on Strap

"Sinn 104 St Sa on Strap"

Binta L

Comments about this watch: The watch itself is beautifully made - classic German engineering, in all its handmade glory, it has been a purchase so very worth it. 


You can't really see it in the photo but the strap is a rich, dark brown and it looks great - super versatile. 

Also, the delivery experience was just absolutely incredible - I ordered the watch on a Wednesday and as soon as i placed the order, i received a call to confirm the order in the next few hours. They confirmed I had ordered the watch i wanted, confirmed my address and informed me the watch would ship that same day. 

I was then informed that the watch had arrived in Canada on the Thursday and following duties and such, I had the watch in my hands by Friday!

Nice watch

"Nice watch"

Comments about this watch: Great everyday watch. Not too small or too large with a nice clean dial. the lume is also very good. 


The service provided by WatchBuys was also top notch and I'm looking forward to my next purchase.

Exceptional Watch

Comments about this watch: Love everything about this watch! Motion is great, has a nice clean look, and works for both formal and informal occasions. The strap is comfortable and adds a bit of a rustic look to the watch. Great value, couldn't be happier!

A countdown bezel at last!

"A countdown bezel at last!"

Comments about this watch: Pros: Perfect size for my 7.5" wrist. I've worn it almost non-stop since receipt and with the leather strap it's so comfortable I forget I'm wearing a watch. Extremely accurate so far, to within a couple of seconds a day. Uncluttered face is very easy to read and lume is very good. AND THE BEZEL: WUNNERFUL, WUNNERFUL to quote a famous German emigre to America. It rachets like a tough hand tool, and to accidentally budge it you'd have to whack it against something hard enough that you'd notice. Soooo nice to have a truly practical timing bezel I wish all manufacturers offered them as options. Cons: there really aren't any because I chose this watch after lots of searching, but the AR and day wheel bear mention. The AR issue may be unavoidable, and the problem is the alteration of the face color. In general lighting situations the face looks sorta "light black," unlike in Sinn's photos. To me it makes the watch look even more toolesqe than I wanted, but I'm probably the only person who n... - more details

Solid, quality watch

"Solid, quality watch"

Peter

Comments about this watch: Have had this watch for a couple of weeks now; it is the right size, is comfortable on the wrist, keeps very good time, and the lume lasts well into the night. Sinn has a winner here.

Absolutely loves it

"Absolutely loves it"

Vinay

Comments about this watch: Bought this as a gift for my father-in-law when he turned 60. He's been wearing it almost every day and he absolutely loves it, this watch is built really well, it looks great on the wrist and the best part of the watch i think is the contrast between the white and the black. 


Also, it's really worth mentioning that as soon as i ordered online, i received within 24 hours a call from WatchBuys explaining the process, describing the watch and the tests they perform, confirming that they'll be shipping it right away, which I promptly received a confirmation of.... bottom-line, great people to buy a watch from, very knowledgable and extremely professional! 

Same experience I had at their roadshow in NY.

Great Every day Watch

"Great Every day Watch"

Mason

Comments about this watch: I've been wearing this for about a month now.

It is perfect as an every day wearing watch. Not too large, not too small, robust, solid, and ready to take a beating. I also enjoy the vintage aesthetic and simplicity of the face.

The lume is pretty good too.

Bang for the Buck

"Bang for the Buck"

Comments about this watch: The 104 is a no brainer.

The size is excellent and a very comfortable watch to wear. I don't time watches but after a day of wear it's right on with my iPhone.

I'm not much for the strap but that's personal preference. One thing that I was really pleasantly surprised with is the lume on this watch. It is fantastic! Recommended.

Love this watch!

"Love this watch!"

William G

Comments about this watch: This Sinn 104 is an exercise in simplicity, practicality, and reliability... all in an aesthetically pleasing timepiece. I am a professional photographer who sometimes photographs at nights, using long, manually calculated exposures.

While legibility in the daytime is extremely good, I love the legibility of this timepiece at night! If the lume is well "charged" I can work for hours into the night. Give the way I use this timepiece, an added benefit is that the rotating bezel is of a "count down" design rather than elapsed time (like most dive watches).

While I can work with either, it is far more convenient to know that my exposure is finished when the minute hand reached the "pearl", as opposed to counting minutes from the "pearl" to control my exposure times.

I would have no hesitation in recommending the Sinn 104 St to anyone who needs a simple but well built timepiece, capable of filling many different roles.
