We Heard You!

Road Show after Road Show, and really any event we have sponsored or attended, the cry has been loud and vocal over the past four years - why not make a matte version of the best selling Sinn 104 Series?

And while you are at it, skip the CNC machine and bead blast the watch (all parts completely by hand?)

Well, it took a while but the work is done and the watch is stunning.  The matte finish changes the complete character of the watch, tones down the shiny finish and helps to hide scratches.

The Sinn 104

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. 

Matte Hand Finished Bead Blasted Case

Until now, all variations of the Sinn 104 featured highly polished cases.

We became curious as to how the watch would appear in a more subtle, matte finished case after feedback from our clients and Road Show guests.

After finally seeing this watch in person, we believe that this is one of the most interesting and collectible in the series as it takes on a completely different look.

In keeping with the traditional methods of production of this watch, we asked Sinn to use hand bead blasting techniques. Rather than produce the case on an automated CNC machine which also would bead blast the case, Sinn first produces the case as a standard 104 case and then the matte bead blasted finish is created entirely by hand.

This hand finished blasted finish produces a striking result, and is a time consuming process to correctly complete.  The end result is everything that you've always liked about the Sinn 104, but in a more subtle design and without the highly polished finish.

Another advantage to the matte bead blasted finish is an increased resistance to showing scratches and other blemishes, which are much more visible on a highly polished case.

Classic Design

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 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.

  • Case made of stainless steel, hand bead blasted matte finish
  • 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

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).

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.

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.

Great service & great product

"Great service & great product"

Verified Owner Comments: Great experience. I would highly recommend Watchbuys. The site was easy to use with lots of good info. about the product. Amazing free shipping. Only took two days to get after I ordered. I appreciate the followup call after I ordered to verify my address, go over return policy, and answer any questions I had.

The watch is great. Came in perfect new condition, as expected.

Sinn 104 - A Timeless Classic

"Sinn 104 - A Timeless Classic"

Verified Owner Comments: The Sinn 104 has become my everyday watch. The 41mm case is a perfect size for my 6 7/8 wrist. I ordered the black dial/matte finish limited production run because of its ability to resist scratches when worn in daily activities. The subdued black dial coordinates perfectly with the white indices, and the syringe hands are a perfect touch.

I ordered mine with the brown leather strap, and I feel the brown strap/black dial combination works perfectly. The very fine hands, along with detailed sub-minute indices allow you to read the time with great accuracy. On top of all this, the SW 200-1 movement is keeping very accurate time. There really isn't anything not to like about the Sinn 104. I highly recommend this watch.

My experience

"My experience"

Verified Owner Comments: Love the 104 it's everything I expected out of a quality tool watch!

WatchBuys customer service is definitely some of the best that I've dealt with. Both Watchbuys and Sinn I would highly recommend! A++ experience

Incredible Watch

"Incredible Watch"

Verified Owner Comments: I bought the watch and wasn’t sure what to expect. I’ve never purchased through an online dealer like WatchBuys before but it was all very smooth.

I selected the matte finish and it is stunning to look at, the angles and sides all catch and diffuse the light spectacularly. 100% worth the money.

Great Watch! Great Customer Service

"Great Watch! Great Customer Service"

Verified Owner Comments: I absolutely love my new Sinn 104 matte edition It's easily one of my most comfortable watches and looks fantastic with the dark brown strap. It will stay on my wrist for days and days.

This is the second watch I have bought from Watchbuys and they are fantastic to work with and are second to none in their professionalism and responsiveness. They totally understand how to treat their customers, and I am absolutely one for life.

Beautiful Tool Watch

"Beautiful Tool Watch"

Verified Owner Comments: I'm absolutely in love with the 104 and specifically this matte edition. I can't take it off my wrist! Shipping was blazing fast and received it within 2 days.

I received a call from costumer service about 10 minutes after confirming my order just to thank me for the order and answering any questions I had. Good customer service and the watch is running great!

Sinn 104 St Sa Matte

"Sinn 104 St Sa Matte"

Verified Owner Comments: Absolutely love this watch. Went back and forth it and the polished version and I’m very happy I went with the matte edition. Very sharp looking watch that has held VERY accurate time right out of the box.

Watch Buy’s customer service was unmatched. Definitely will be buying more Sinn’s from Watch Buys in the future!

Sinn 104 Special Edition

"Sinn 104 Special Edition"

Verified Owner Comments: This was my first Sinn purchase and my first purchase from WatchBuys. I am extremely pleased with the quality of the Sinn and will be adding additional models of their timepieces in the near future.

As for WatchBuys, the transaction from start to finish could not have been more efficient, professional, courteous and friendly. I have never had a watch dealer call me after a purchase but they did! A genuine pleasure to deal with.

Easy to Order

"Easy to Order"

Verified Owner Comments: I was able to order this for my friend across the country. Watch Buys worked with me (on a Saturday!) to make sure my order wasn't fraudulent and was going to the right place.

The shipping was fast and neat, and the watch is great!

No regrets.

"No regrets."

Verified Owner Comments: I sold a standard, polished Sinn 104 to purchase this special edition and I have no regrets. I think the matte finish is a much better match to the character of the 104.

The finish is well done and the bezel, crown, and strap buckle are also matte to match the case. I like the countdown bezel and find it more practical in daily use than the elapsed time bezels on most tool watches.

The strap is better than expected. Thick but flexible, it was broken in by the second or third day of wear. My only complaint is that the crown can be difficult to pull out once unscrewed. The amount of force required makes it hard to know the crown position and I sometimes end up adjusting the date when I intended to manually wind the movement. I expect this to get easier with use.

Overall I am happy with my purchase.

Perfect in matte finish

"Perfect in matte finish"

Verified Owner Comments: The matte finish is simply stunning. The watch came perfect with no noticeable flaws. The watch wears perfect, if slightly smaller than a 41mm, because of the lug angles. Sits fairly low on the wrist.

The suede strap was a perfect match for the matte special edition. Well done!

The Finest Form and Function

"The Finest Form and Function"

Verified Owner Comments: If you’re looking for a watch that combines aesthetic with function, look no further. The bezel is actually functional as a timer, not just another dive watch piece of eye candy. The watch face provides precision and incredible legibility. It is a beausty.

Perfect everday watch

"Perfect everday watch"

Verified Owner Comments: In August of 2018, I purchased my first SINN watch. A 104 sa i: I have now replaced it with the special edition matte version.

If SINN had made this two years ago, I would have purchased it in a New York second.

This is now my absolutely everyday-perfect watch. I changed out the strap to a black Hirsch performance strap and the watch is now ready to go. As always - impeccable customer service and shipping. (this was my fourth purchase from Watchbuys)

Beautiful Watch!

"Beautiful Watch!"

Verified Owner Comments: I bought the Matte version of the Sinn 104 as my first real timepiece purchase. I'm over the moon with how this watch looks and functions, and have received a number of compliments. I finally have a nicer watch to wear than my apple watch when I want to dress up a bit, and it's taking over daily wear duties very quickly!



Verified Owner Comments: The watch is wonderful, meets all expectations. After a few weeks of wear I have determined it runs approximately 6 seconds fast per day. The matte case is fantastic. Sinn quality!

Update after 2 months of ownership: Watch accuracy has improved to approximately 2.5 seconds fast per day.  Watch is absolutely impressive!

matte finish makes it perfect

"matte finish makes it perfect"

Verified Owner Comments: I always liked the 104, but not the polished finish. Grabbed the matte version as soon as it became available, and it makes a great less dressy everyday watch. Looks great on a variety of straps. Case size and shape make any 104 easy to wear.
