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 Fine Link stainless steel bracelet

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.

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.

First Sinn watch

"First Sinn watch"

Verified Watch Owner Comments: I really like my 104 and the fine link Bracelet which is a very comfortable Combination. The face is super legible And I like the syringe style hands too. I’m glad I chose the white version but the black is great too.

Fantastic!

"Fantastic!"

Verified Watch Owner Comments: Everything about this transaction was fantastic. The customer service was exceptional.

The watch itself is even better in person. The build quality is comparable to my Omega's. Legibility is outstanding. I purchased the fine link, but this watch will be a strap monster. I will definitely purchase from Watchbuys again.

Sinn 104 I St Sa White of Fine Link Bracelet

"Sinn 104 I St Sa White of Fine Link Bracelet"

Verified Watch Owner Comments: I wore my 104 for a few weeks before writing my review. I highly recommend Sinn and specifically the 104. The build quality is comparable to my Omega Watches (Seamaster 300m, Aqua Terra Chronograph GMT, Speedmaster First Omega in Space, Speedmaster Broad Arrow GMT, De Ville Hour Vision). The bezel lines up exactly on the hour markers (120 click) with a firm positive clicking engagement. Winding the crown has a smooth quality feel, comparable to my Omegas. I got the white dial on fine bracelet. The black outline on the hour markers give the appearance of "applied indices” which adds another layer of detail that is not apparent with the other dial colors. The "fine link bracelet” also adds a level of refinement. It is very comfortable and provides a perfect fit on my 6 7/8” wrist. The bracelet comes with four full size and two ¾ size links, providing a modest amount of adjustment. Not everyone will find the "perfect fit” with this bracelet. I got lucky. I have received many complemen... - more details

Sinn 104 White

"Sinn 104 White"

Verified Watch Owner Comments: Regarding the watch, the Sinn 104 with white dial looks very sharp. Everything feels great from the crown to the bezel and on the wrist. My only cautions are with the fine link bracelet. While it looks fantastic with the watch, it is a scratch magnet. Especially at the clasp. Desk divers use caution. Also changing the bracelet out can be a hassle since the watch does not have drilled lugs and the bracelet fits very tight to the watch (a good thing).

Watchbuys was fantastic to work with and I wouldn't hesitate to buy from them again. The watch was shipped the day after my order and it came in perfect condition.

Superb Product and Purchase Experience

"Superb Product and Purchase Experience"

Verified Watch Owner Comments:

This watch exceeds anything else at its price point. The build quality and finish surpass that of watches that are twice the price.

Furthermore, the WatchBuys Team was great to work with throughout the purchase. Communication during the purchase was awesome. The watch was delivered as scheduled and in perfect condition. Knowing that I could easily reach a WatchBuys rep at anytime throughout the transaction, for any questions or concerns, was also very reassuring.

And there is additional value in that. I definitely recommend Sinn and WatchBuys if you are in the market for a German-made watch.

Sinn 104 I St Sa White on Fine Link Bracelet

"Sinn 104 I St Sa White on Fine Link Bracelet"

Verified Watch Owner Comments: I love this watch, but if this will be the first Sinn 104 purchase for someone's collection, I think that the better pick would be the black dial version of this model. The black is one of the most versatile watches made by Sinn. The white is probably more fitting for sporty summer wear.

All versions of the 104 are great. I love the feel of the ratcheting bezel.
