Limited Edition

The new Sinn 104 I St Sa RS Limited Edition features a striking red seconds hand set against a black dial.  The "RS" stands for Red Seconds.

The Sinn 104 I St Sa RS Limited Edition is limited to 200 pieces, and is exclusive to North America, Japan and Australia.

An engraved, limited edition marking on the watch rotor adds to the uniqueness of this piece.



Classic Design

Since its introduction in 2013, the Sinn 104 Series has quickly become one of the best selling watches in the company's history.

Its design is inspired by Sinn's roots: simple, legible, and without clutter or gimmicks. 

Although the overall design is inspired by 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 trying to brush up on your German language skills. 

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.



Important features of this watch include:

  • Case made of polished stainless steel
  • Captive pilot's bezel with minute ratcheting
  • Sapphire crystal glass on both sides
  • Water resistant to 200 meters
  • English and German day display
  • SuperLuminova on the hands and hours (glows green)
  • Low pressure resistant
  • Sporty red seconds hand
  • Limited edition of 200 pieces

This watch is fitted with a black, vintage style leather strap with red stitching.

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 FedEx 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.

  • View Sinn watches in the EZM Series.



DIN 8330 / 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 existed for example for diver's watches.

The new "Technical Standard for Pilot's Watches" (TESTAF) and DIN 8330 were originally developed by the Aachen University of Applied Sciences and establishes the suitability for professional use as a pilot's watch.

Solid watch!

"Solid watch!"

Verified Owner Comments: Great watch!

I bought the red seconds hand but I would have bought the regular 104 st sa too. I love this watch! I bought it on the black strap which is very nice. Case is a perfect size and I love the syringe hands.

It also came with the day, date, and time set which was a nice touch.

Excellent watch and service

"Excellent watch and service"

Verified Owner Comments: This watch is every bit as good as all the online reviews say it is. It's very accurate and easy to read at a glance. I love the syringe hands.

The band on this model is one layer of black leather. No stitching or sewn on back It's soft and comfortable, and won't show sweat marks over time.

The customer service is as good as the product. I had some problems placing my order online (my fault) and in no time we were able to work things out over the phone.

Excellent watch, excellent service from WatchBuys

"Excellent watch, excellent service from WatchBuys"

Verified Owner Comments: This Sinn 104 is probably one of my favorites, in my collection (Rolex, Omega, Seiko). The watch is crafted with high quality materials, feels high quality, and also feels like it can take a beating.

I love the design, the red accent on the hands and the stitching on the straps really give this timepiece a nice touch. I highly recommend this watch to any enthusiast.

Watch Buys also impressed me with their after purchase follow up call, and their communication regarding purchase and shipping was on point. Definitely highly recommend Watch Buys, and will also come back here for future watches.

Outstanding Watch, Glad I Took the Dive

"Outstanding Watch, Glad I Took the Dive"

Verified Owner Comments: It can be a little daunting to buy a watch without trying it on in person first, or seeing how it looks in not-a-photo, so I'm hoping my review can help any potential buyers with their decision. First, a few surprises when I got the watch physically in my hands: 1) The watch wears much lighter and smaller than I expected (especially compared with my 41mm BB GMT - yes I know its known to be a chunkier watch), with the straight, non-wrap-around lugs being the main difference maker in creating that impression of case compactness. It's pretty much a perfect fit on my wrist (6.5) 2) The dial is far from flat even though its printed the red seconds hand, day-date window, bezel, and quarter minute track there's plenty going on on the dial to keep it interesting all the time. At the same time, none of it is enough to distract you from telling the time, so there's no ooo pretty watch [forgets to read the time] syndrome here. It's a tool first, but then also manages to do it while looking ve... - more details

Sinn 104 I St Sa RS

"Sinn 104 I St Sa RS"

Verified Owner Comments: The red seconds hand on this watch certainly stands out and adds a little attitude to an already stunning and recognizable piece. The included black leather strap with red stitching makes it stand out even more, but it also looks great with a variety of more understated straps (brown leather, black silicone, etc).

It was a pleasure to buy from WatchBuys - they're very personable and took the time to talk with me on the phone about the watch and my shipping preferences. Will definitely be back.

"Sinn 104 I Sa RS"

Verified Owner Comments: Visually, it is very easy to see the time at a glance and I appreciate having the Day/Date feature. The luminescent is very bright and long lasting. The watch is striking in appearance and it keeps very accurate time.

Sinn 104 RS

"Sinn 104 RS"

Verified Owner Comments: Outstanding experience all the way around. I was a little apprehensive at first to buy this watch based on YT reviews and pictures alone. So glad I took the chance and utilized Watch Buys.

Customer service was outstanding watch showed up on time and looks great.

Great watch, excellent customer service

"Great watch, excellent customer service"

Verified Owner Comments: This was my first Sinn purchase and first experience with Watchbuys, and I'm really happy with both. The watch is stunning in person, I love the matte black dial and subtle pop of color with the red seconds hand. It fits really well on my 6.75in wrist, although I think this watch would look great on most wrist sizes thanks to its dimensions and understated thickness. After reading other reviews I had low expectations for the lume but I've been pleasantly surprised at its brightness. The leather band is also impressive, it's thick and robust and adds to the whole tool watch feel. It's obviously a sportier look than some of their other versions of the 104, but I think it still looks dressy enough for a formal occasion especially if put on one of the Sinn bracelets. In terms of customer service, I emailed Watchbuys before purchasing sharing my concern with the leather strap being too long for my wrist, and they responded quickly saying they would happily substitute a shorter version o... - more details

Simply The Best!

"Simply The Best!"

Verified Owner Comments: I’ve purchased 3 Sinn watches from WatchBuys and have nothing but high praise for the watch brand and the seller.

Sinn defines style and quality while WatchBuys stands out as the best company I have dealt with for courteous and rapid service. Keep it up!

Amazing watch - Fantastic service!

"Amazing watch - Fantastic service!"

Verified Owner Comments: I love this Sinn 104 limited edition! It just looks stunning on wrist and has been the envy of several of my watch collecting friends who immediately tried to buy it only to find it was sold out.

About the only thing better than the watch was the fabulous service from Watchbuys straight through from purchase to after-delivery follow-up. A+ service in my book. Will be back for more.
