Product Details

Background of the U212 Designation

The U212 and U212A are the cream of the German submarine crop - they represent Germany's excellence in both technology and construction. The submarine was designed for the navy in both Germany and Italy, and is non-nuclear.

The propulsion system is quite unique - it uses hydrogen/oxygen propulsion. This method had been considered before, but was deemed a health and fire risk.

The German U212 and U212A have developed a system to relocate the tanks and change the way the mixture is used, making this propulsion system safe. This submarine can stay submerged for up to three weeks.

This cutting edge technology and excellence in engineering is what Sinn brings to the Sinn U212 EZM 16.

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).

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.

U212 review

"U212 review"

Verified Watch Owner Comments: I’m very pleased with this watch. It has a very substantial look to it, but is not flashy, so does not attract attention. Fits beautifully and was easy to adjust the strap. I like the fact that you can make minor length adjustments with the deployment buckle. And it’s very comfortable to wear!

Love it

"Love it"

Verified Watch Owner Comments: I love the watch!! Thanks!



Verified Watch Owner Comments: Recently added this amazing timepiece to my Sinn collection. My largest Sinn to date, and a very impressive watch it is! I enjoy wearing watches as large as 48mm, and so this 47mm Sinn feels very comfortable on my 6.75” wrist. I really appreciate the precision and extreme legibility of the dial and the incomparable quality of the Sinn craftsmanship. A very welcome addition to my Sinn watch collection.

THE rugged dive watch

"THE rugged dive watch"

Verified Watch Owner Comments: I am a previous customer, and a pilots watch fan. I wanted to buy a diver that didn't look tiny on my 8 ¼ inch wrist and decided on the U212 on the strap. What a fantastic watch. All clean purposeful design and no flash. I wear it as much as my previous favorite, the EZM 9.

I have owned Rolex and Seiko high end divers, but this watch is in a class by itself. It is incredibly accurate and a joy to wear. It will fit more wrists than it appears to at first.

The service was excellent. Rob upgraded me to overnight so that the watch would not sit somewhere during the Labor Day weekend before delivery. You cannot ask for better service.

The REAL U-Boat Watch

"The REAL U-Boat Watch"

Verified Watch Owner Comments: German submarine steel? Yes please. I initially purchased and then returned the U1 because its hands and size just didn't appeal to me the way the U212's did. At 47mm, the U212 is definitely a manly watch. I have to mention that it does present smaller than many similarly-sized watches. The curved lugs fit well within the bounds of my 7 inch wrist. While this model isn't for everyone, it distinguishes itself among its SCUBA-capable peers with its clean face, undeniable wrist presence, and unique Sinn technologies. Details I like: Its military submersible namesake. The oversize and thoughtfully-positioned screw-down crown. Sword hands. The selective use of red text. The tonal Argon symbol. Did I mention German sub steel? The only nice to have detail I'd have liked to see is a stylized text model number on the case back as seen on other U-series watches. Like the rest of Sinn's collection, you're getting a lot of watch for the price. Not only is it a delightfully overengineered profess... - more details

Watch and Watchbuys are FANTASTIC.

"Watch and Watchbuys are FANTASTIC."

Verified Watch Owner Comments: I ordered my Sinn U212 EZM 16 yesterday morning around 10 AM. I received it this morning around 10 AM.

Watchbuys was fantastic. Customer service is second to none. The Sinn U212, I love it. It exceeded my expectations. Fit and finish is fantastic. Both highly recommended.

Highly Recommend the Sinn U212 EZM 16!

"Highly Recommend the Sinn U212 EZM 16!"

Verified Watch Owner Comments: First, let me say I am a repeat customer - and a very happy one at that. I think this is as important as my thoughts on my recent purchase. All my questions prior to purchase were answered immediately and in great detail. Watchbuys provides outstanding service! The watch - overall, amazing. While this is not my first Sinn, it was the first in the larger case size. That said, it fit great on my 7.5 wrist. Accuracy is spot-on and the feel of the watch is solid. I'm by no means a watch expert - I simply 'wear what I like' and Sinn is my favorite - not only for looks but knowing I can wear this watch in whatever condition I see fit - plus it looks great on the bracelet if I want to 'dress it up' a bit. At any rate - I highly recommend the Sinn U212 EZM 16 to anyone's collection but I firmly stand behind my experience as a customer of Watchbuys. These folks are great!!

Sinn U212 EZM 16

"Sinn U212 EZM 16"

Verified Watch Owner Comments: I have owned several Sinn''s over the past few years and while all of them have been remarkable in terms of quality of craftmanship and duribility, I must say that this latest model is the very best. I am a dive watch fanatic and certainly appreciate a solid piece like this one. This model includes all of the parts of Sinn that I appreciated.

It has the clean and solid look in the case of the U1 with the precise but clean hands of the U2 with the ultimate durability of the UX. I was a bit reluctant to have a 47mm size but my concerns were completely unwarranted once I saw this watch and more to the point put it on my wrist. While the size is impressive it is not over bearing or uncomfortable on the wrist. It blends in nicely with a businss casual attire or certainly jeans and a t shirt. I constantly find myself staring at this one on the wrist and appreciate the look more and more each day.

Wonderful job again Sinn and wonderful customer service and speed by Watch Buys!!
