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.

My New Do Anything/ Go Anywhere Go To !

"My New Do Anything/ Go Anywhere Go To !"

Verified Watch Owner Comments: First: I want to say I was drawn to this watch for it's fantastic blue dial and applied indices. I've always admired the 556's various versions but the more simple painted dial just never screamed buy me... the blue did ! (spoiler alert the dial more than lived up to hype) Second: I bought in addition to the FINE LINK the more traditional band the H Link Bracelet (I've owned that style before and loved it.) So just in case I didn't love the Fine Link and considering the drilled lugs I figured I could have two different style watches for just a smidge more than the price of one. ( lastly If I had concerns about adjusting the fine links sans micro adjustments I could always fall back on the H link for daily wear) Impressions: Let me tell you everyone at work including some serious watch geeks, all love the fine link, they think the traditional H link is great, but the Fine link really caught their attention. And as it turn out so many people I come in contact with when I wear this be... - more details

Sinn 556ib

"Sinn 556ib"

Verified Watch Owner Comments: This is my third Sinn watch. This has to be my favorite, never a big fan of blue watch dials but this dial is beautiful. Watch accuracy is fantastic, bracelet is really comfortable.

Watch size is perfect on my 7 1/4 inch wrist. Dealing with watchbuys is a pleasure. Quick response to any questions and very knowledgeable about their products.

Great service

"Great service"

Verified Watch Owner Comments: The watch exceeded expectations. Ordered on Tuesday. Watch delivered to Toronto Canada 12 hours later.

Watchbuys paid all shipping and brokerage costs. All I had to pay was local sales tax plus 5% duty. Highly recommend purchasing from this source. Five stars all around....

Awesome watch

"Awesome watch"

Verified Watch Owner Comments: The picture doesn’t do this watch justice it looks even better in person. Keeps within 5 seconds per day so far. Quality of the watch looks and feels superb.

Customer service was great too. I asked if I could swap the fine link bracelet for the one seen on other 556 models. I got a call within minutes to tell me they would be happy to accommodate and credited me the difference.

Classic Blue dial mens watch

"Classic Blue dial mens watch"

Verified Watch Owner Comments: The dial is much more handsome in person than any pictures I have seen. Nice and simple and the blue dial looks mostly utility in normal lighting. Then when the light is right the dial shines and the nice silver markers light up and it looks brilliant. A great watch on a handsome mans band for the price.

Plus 8 seconds over 3 weeks. I really like the no date feature. That is how I bought my Sub....no date to fuss with. My eyes can't see a date anyway. Highly recommend this watch. Only hesitation for trendy buyers might be the lack of size. I really like it and wanted a metal band for summer.

Perfect watch for everyday

"Perfect watch for everyday"

Verified Watch Owner Comments: Great customer service and communication from watchbuys. The watch is perfect. Simple, well built and acurate. More accurate than my Omega seamaster. Sinn definitely make some nice watches.

Very pleased

"Very pleased"

Verified Watch Owner Comments: This is a great watch. Great looking, great size, comfortable to wear and extremely accurate (thus far) at +1 second/day....thats better than any of my COSC certified watches have been able to achieve (with exception of Brietling Aerospace and Tissot PR100 Quartz Chronometer, both with HAQ movements). Really impressive.

If I had to make a couple suggestions to Sinn it would be !. to engineer and offer a micro adjustable clasp. 2. make sure all distributors are aware not only what their territory is, but who their fellow distributors are so a customer can be guided correctly and directly if they happen to live in a part of the world where their nearest distributor is not in fact their distributor. But in regard to the watch itself, could not be more pleased!

Superb Wrist Presence

"Superb Wrist Presence"

Verified Watch Owner Comments: This watch has to be seen on-wrist to be fully appreciated. The rich blue dial is very understated until viewed in full sunlight where it truly reveals its glory.

The applied indices give this model a true sense of luxury over the printed dials of the 556 A and 556 I black dial. The fine link bracelet is one of extreme quality with an excellent double deployant clasp that has no equal. It is also thinner and quieter than Sinn’s H-link bracelet albeit a trifle less comfortable.

This watch would make a great 1 watch collection.

Perfect one-watch

"Perfect one-watch"

Verified Watch Owner Comments: Perfect one-watch. Slim yet sturdy. Rugged and sporty yet perfectly acceptable in dressy occasions at the same time. No date means no fuss. Strap monster. This is one beautiful watch.

I bought it for a graduation gift for my son but wish I bought this for myself over my IWC Mark XVIII Le Petit Prince. By the way, the georgeous blue dial on this Sinn watch leans more toward a purplish-blue than my IWC’s medium-blue dial, but is equally beautiful.

556I Blue

"556I Blue"

Verified Watch Owner Comments: Pictures don't do this watch justice. It has to be seen in person.

Sinn did a great job with this one. Hope to see more variations in this configuration, without the date and with the applied hour markers.

Fantastic!

"Fantastic!"

Verified Watch Owner Comments: I own both of the older A and B dial models and have enjoyed them. But this version really blows them away and takes the series to the next level. The fine link bracelet is definitely an upgrade from the H type and the watch as a whole wears very comfortably. The sunburst dial is gorgeous as is the color. Case finish is very nice indeed.

What I really love though is the way the light plays off of the indices and hands, which totally livens up this piece compared to the older all white scheme. If you were only going to get one Sinn and didn't want to go the larger diver route I would say this as good as any model they have put out so far and that is saying a lot!

556 I B

"556 I B"

Verified Watch Owner Comments: I recently purchased a 556IB w/ fine link and I must that I couldn't be more pleased. I set it to Atomic Time and if it's lost time I can't see it. I have had numerous nice comments.

The service from Watch Buys has been spot on and I will definitely use them again.

Great watch!

"Great watch!"

Verified Watch Owner Comments: I've been looking at Sinn watches for a few years but, for whatever reason, didn't purchase one until the 556i B came out. The simplicity without the date complication, the clear indices and that fantastic blue face. Photos don't do it any justice!

WatchBuys was fantastic throughout the purchase process and I couldn't be happier with the experience and look forward to doing business with them again.
