The Long Requested Watch

We have received requests for this Sinn watch for a long time.  In fact, it seems at every Road Show event one of the first questions we are asked is "When will Sinn make a version of the Sinn 104 with a blue dial?"

Sinn has created a deep blue dial using traditional ornamental grinding techniques to produce a sunburst pattern.  The color of this dial will change depending upon the light and angle producing deep, rich colors of blue in various shades.

The result is a striking Sinn 104 I that rounds out the collection.

Although the Sinn 104 I St Sa B takes 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 trying to brush up on your German language skills.

Everything about this watch is top notch, from the chronometer grade movement to the sapphire crystals used on both front and back, and the design and finish of the case leave no doubt that it's a Sinn.

This pilot's 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 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
  • Rich blue dial with sunburst decoration

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.

Couldn't be happier

"Couldn't be happier"

Verified Watch Owner Comments: This beautiful Sinn 104 is my first new watch in 24 years (!), as my very nice quartz diver watch received as a birthday gift) is reaching the end of the road. Going online to learn a little bit about what's out there, I fell down the rabbit hole and become at least somewhat obsessed with learning about the watch market, and German watches (especially Flieger watches) in particular. Of course, I had never heard of Sinn before, but quickly became enamored with them, and expected to do some brick and mortar shopping during an upcoming visit to Munich. However, that plan went out the window after learning about Watchbuys. I placed my order at Watchbuys on Feb. 16, and the watch arrived the very next day!! My wrist is over 8 in circumference, so I quickly decided to get a couple of extra links for the bracelet. Called Watchbuys and had a great experience Kevin in service took care of my order right away. The entire buying experience was extremely easy, the prices were right, and the pr... - more details

Verified Watch Owner Comments: My new go-to everyday workhorse that can be dressed up or down. A true if you know you know watch freak piece that is extremely wearable both on leather and steel.

Wonderful experience dealing with Watch Buys throughout the convenient process. If you get one, you will not regret it. Thanks for everything, Trey!

Great 1st Purchase from WB...

"Great 1st Purchase from WB..."

Verified Watch Owner Comments: First off, the buying process, details, and follow through from Trey, and later John, was fantastic. I felt very comfortable purchasing from this reputable authorized dealer (AD) for Sinn. If there's every another watch I want, I'll be looking here first.

The packaging and delivery was earlier than expected and bulletproof. The watch looks great, and was everything I'd imagine it would be. IMO, I think the Sinn 104 is the nicest looking watch in the Sinn family. Thank you Trey and John, BaiHu

Gorgeous watch

"Gorgeous watch"

Verified Watch Owner Comments: This is my first luxury watch purchase and I’m super happy with it. I grin whenever I look at it - it’s just fantastic. The sapphire glass (both sides) is always a plus for me, as well as the screwed crown The lume is great and I love the instant date change.

The countdown bezel is a neat feature (I’ve only had dive bezels so far). Its sharp angles fit perfectly and the relatively thin case still impresses me. The H link bracelet fits well and is comfortable enough - but I prefer rubber & textile straps, generally. So I bought a couple, along with a Sinn leather strap and a blue seatbelt NATO - all look great on the 104! The shiny case is a bit of a fingerprint magnet, but you get over it pretty quickly when you see that dial in sunlight.

The bi-directional bezel has solid clicks and no play. The rotor is nicely finished and the movement is a pleasure to look at through the display case back. Sinn made a great one with the 104 and it’s been worth every penny for me.

Verified Watch Owner Comments: Great customer service and prompt shipping from Watchbuys.

The blue dial is really eye catching and plays with the light very nicely. Sometimes it almost looks black, but then in other light it takes on a nice royal blue. After about a week, the watch is running about +/- 4 seconds a day whi h exceeded my expectations. I'll also say that the finishing on the movement is quite nice with the blued screws and custom Sinn rotor.

In my opinion, this watch punches far above it's weight class. I can't take it off wrist. It looks great casual, it looks great with a suit.

Perfect Watch
