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.

My First Sinn

"My First Sinn"

Verified Watch Owner Comments: I spent a couple weeks traveling with a diver with no complications. As I lost track of what day of the week it was as well as the date I began to fantasize about a watch that kept track of both for me. I watched review after review and fell in love with the 104 with numbers.

I couldn't believe I could get my hands on such a legible watch with the same 200 meter water resistance as my diver, with a display back, and all for roughly half what I paid for what I was wearing. I was not disappointed in any way. I love the legibility, I love the dial, and I have used the bi-directional bezel far more than I ever did on the diver style. I bought the bracelet version because isn't that what you're supposed to do?

I promptly used my Watchbuy points to pick up a Sinn leather strap and it is such a classy look. But wait, now the leather will be destroyed at the gym. Maybe I need something like a UX to compliment this one...

Clean, Simple, and Functional

"Clean, Simple, and Functional"

Verified Watch Owner Comments: Simple design but does not skimp out on functionality. The numerals, the syringe style hands the count down bezel are clear and have great visibility day or night. The bracelet is decent and has the nice feature of the diver extension if you would ever need it. the day and date complication great and is instantaneous. Cons Not many but the clasp is friction fit and is some times difficult to take off but does break in eventually and isn't as bad. The power reserve isn't the greatest and can be an inconvenience went it dies and you have to reset the day and date. Overall I would definitely recommend this watch because you can dress it up or down and is a great everyday watch.

What a watch

"What a watch"

Verified Watch Owner Comments: Loving my new 104. Bracelet fits perfectly (h-link) and the dial is incredibly legible.

Sinn 104 - Awesome Watch

"Sinn 104 - Awesome Watch"

Verified Watch Owner Comments: I've worn my Sinn 104 with H Link Bracelet for several weeks now it's an absolutely perfect watch. Easy to read numerals, surprisingly useful timing bezel (why are these so rare? they are super practical for cooking), excellent lume and not too flashy.

I wanted a tool watch and this is perfect. The one flaw in this setup is not the watch but actually the bracelet clasp: Sinn, if you are reading this, please for the sake of everyone's fingernails make an H-link bracelet clasp with a two button release. The bracelet itself is excellent but the clasp is super annoying to open. If I was buying again, the fine-link bracelet might be worth the extra cost if the clasp is better.

Very happy with the 104 A St Sa

"Very happy with the 104 A St Sa"

Verified Watch Owner Comments: After having considered the 103 St Sa for some time but being concerned it would be too thick at 17mm, I decided to go with this 104 A St Sa for the same aesthetic except without the chronograph functionality at a much more manageable 11.5mm thick. It is shirt-cuff friendly and much less likely to get bumped. The 41mm diameter is a good, understated size for my 7.5 wrist. Fit and finish is excellent, and the bezel rotates smoothly with very positive 1s detents. Used for timing, the count-down pilots bezel can be an adjustment if you're used to a count-up divers bezel. The highly polished case dresses it up for office or dressy-casual wear, but may be a bit much for casual weekend duty depending on your tastes - the matte may be better suited for that. Accuracy has been good, after wearing daily for a few weeks it has settled into a steady +3s per day, within COSC Chronometer standards. Overall, very happy with my purchase. Lastly - the purchasing experience from WatchBuys was exc... - more details

Amazing watch and great customer service

"Amazing watch and great customer service"

Verified Watch Owner Comments: Watch exceeded all of my high expectations. I read a lot of articles and reviews about Sinn prior to my purchase and the hype is warranted. Love the dial design and bidirectional bezel. The 41 mm diameter fits nicely on my 7 wrist.

Prior to my purchase, Watchbuys answered all of my questions with quick replies. Customer service was excellent and I will definitely buy again from Watchbuys.

Easy to read, very accurate

"Easy to read, very accurate"

Verified Watch Owner Comments: I love it. Fits perfectly my 6 3/4” wrist. 3-5 secs/day!

Great Watch for Everyday Wear

"Great Watch for Everyday Wear"

Verified Watch Owner Comments: At 41mm case diameter with a 48mm lug-to-lug, this fits well on my small 6.25 wrist even with the standard H-Link bracelet. Very little slip when adjusting the minute hand so you can precisely place the tip on the chapter ring markers.

Out of the box, Timegrapher indicates +2 sec / day with dial up, but in use, deviation is 0 to -1 sec / day. Legible arabic numbers on black glossy dial with both day and date displays make this a great daily wear watch.

A wonderful watch

"A wonderful watch"

Verified Watch Owner Comments: This is my everyday watch. I wear it 24/7. The h link bracelet is very comfortable and was easy to adjust. I own many automatic watches (Omega, Seiko, Hamilton) and this is my most accurate.

It averages an incredible 0 seconds a day to -1 second a day. I would recommend this watch.

Very Versatile Watch

"Very Versatile Watch"

Verified Watch Owner Comments: The 104 is one of the best all around watches I've ever owned from any brand. I don't say that as a Sinn fanboy, either, as this is the first Sinn I've had. I chose the Arabic dial because to me it gives the watch a blend of pilot, field, and dive characteristics. The watch is extremely legible and the lume lasts long enough to be readable at 5 in the morning. The countdown or mission timer bezel is very handy for daily tasks. Speaking of the bezel, mine is spot on in terms of alignment and the action is wonderful. The 104 dresses up nicely or can be very casual depending on the strap of choice. It's thin enough to easily slide under shirt cuffs if that's a consideration and wears nicely with the down turned lugs. Even though it isn't marketed as a dive watch, the screw down crown and 200m of water resistance are certainly great features to have. If I was looking for a one watch collection, this would be a very strong contender. The only thing I wish Sinn would do is add drilled lu... - more details

Incredible quality and overall fit. Movement is beautiful.

"Incredible quality and overall fit. Movement is beautiful."

Verified Watch Owner Comments: I was a little concerned with the overall sizing of this watch but it actually fits incredibly and comfortably. The dial finishing is superb along with the look of the movement through the back. A watch that will always be in my collection.

A worthy stunner

"A worthy stunner"

Verified Watch Owner Comments: I've been interested in the Sinn line of watches for a long time. I finally ponied up enough funds to get the Sinn 104 Arabic and I am extremely satisfied. I was torn the arabics or the white but settled with the more tool design of the arabics.

A very reliable watch with a tank like design that looks good in business suit or Jean and a t shirt. Something that's not really pointed out in every review is that the watch has very very good temperature ratings as in cold/ hot weather won't affect the accuracy. Since it has a lug width of 20mm, there is a litany of different strap choices that can pair very well with the watch. The pictures don't really do the watch justice, if you can see and wear on in person I highly recommend it. This watch is definitely something to keep.

After having it for a while I now understand why the watch has such a tight hold on its value/ price.

Best dressy tool watch for the $$$.

"Best dressy tool watch for the $$$."

Verified Watch Owner Comments: I love the display back. Quality exceeds the price. If you’re on the fence by all means pull the trigger!

Sinn 104 A St SA, H-Link Bracelet

"Sinn 104 A St SA, H-Link Bracelet"

Verified Watch Owner Comments: After looking at many watches, I came across the Sinn 104 and finally had the opportunity to purchase one from Watchbuys. The watch lives up to all of the reviews you may have seen - terrific finish, solid construction, great dimensions, and a terrific value for the price. I highly recommend the watch, you won't be disappointed.

Watchbuys I can also highly recommend, the whole process of ordering and delivery was topnotch. The owner actually took the time to discuss the Sinn brand and watches in general while I was placing my order. When I'm in the market again and Watchbuys carries the brand I'm interested in, I'll certainly make the purchase from them.

Sinn 104 the best pilot watch

"Sinn 104 the best pilot watch"

Verified Watch Owner Comments: I bought my 104 a few weeks ago and I love this watch. Watchbuys were very professional and great to work with, I kept having issues with my bank declining my purchase (4 times!)

I was immediately called by Watchbuys trying to help get the transaction completed. Saving up for the 903 now!

Sinn 104

"Sinn 104"

Verified Watch Owner Comments: This watch has the perfect combination of dressy/class and sporty/ruggedness. The fit and feel is great.

Buying process from Watchbuys was hassle free with excellent communication. Would definitely buy another watch from Watchbuys.
