Product Details

This is a special version of the Sinn U50 and is produced in very small quantities.  This version features a fully Tegimented (hardened) case and is named the Sinn U50-T.

The Sinn U50-T is all about wearability and versatility.

First, the case size.  For years our clients have requested a midsize version of the bestselling Sinn U1.  The Sinn U50-T checks in at 41 mm, 3 mm less than the Sinn U1 and a perfect size for most wrists.

Second, the case thickness.  At just a hair over 11 mm thick, the Sinn U50-T is even thinner than the popular Sinn 104 and is one of the most comfortable diver's watches in the category.

This case design also provides a 35% reduction in total weight compared to the Sinn U1.

Third, the case material.  The Sinn U50-T case is made from fully Tegimented German submarine steel and features a Tegimented bezel.  

Finally, the water resistance.  Despite the lower profile case size, the Sinn U50-T boasts 500 meters of water resistance.  The same rating can also be expressed as 50 bar, hence the "U50" name.




A Durable 41 mm Fully Tegimented Case

The watch case of the Sinn U50-T is made from the same steel used in the construction of the outer hull of submarines.  The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germany's North Sea shipbuilding yards who construct submarines using the material.  

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.

Another important and practical feature of the submarine steel case is corrosion resistance.  The case of the Sinn U50-T resists the effects of exposure to salt water and salt water environments.



Built for Professional Use

As a Sinn U Series watch, the Sinn U50-T is rated for professional use.

The international testing lab of Germanischen Lloyd has tested the Sinn U50-T and certified it as water resistant to 500 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

The uni-directional rotating bezel is milled from the same submarine steel as the case and is Tegimented. The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths. 

The bold block hour markers are white and offer a stark contrast against the black dial.  The block seconds hand is a bright red.  This unique design gives the Sinn U50-T, and its larger brother the Sinn U1, a distinct look that also provides maximum legibility underwater.



Important features of this watch include:

  • Case made of fully Tegimented German submarine steel
  • Uni-directional Tegimented bezel 
  • Water resistant to 500 meters
  • Date display at 3
  • Low pressure resistant
  • Sapphire crystal with double sided AR coating
  • SuperLuminova on the hands and hours (glows green)

This watch is fitted with a Sinn black silicone rubber strap with a fully Tegimented diver's locking clasp.

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.

Fantastic dive watch

"Fantastic dive watch"

Verified Owner Comments: I’m feeling it’s time for a nice new watch and I could not stop looking at the Sinn U1 & U50. I ultimately decided to go with the U50 - I admit I was surprised at its size when it arrived. I’d been staring at macro photos online for a while and I guess it grew big in my mind.

I’m falling for it fast now that it’s on wrist. I’m digging the slightly smaller size more and more. The strap parts and rubber feel top notch - the rubber does attract dust, but it’s not a deal breaker (and their H-link bracelets are great if you go that route). This isn’t my first Sinn and I usually want to spread my more expensive brand names around - but this one was too fun to pass up. It makes me grin whenever I look at it. I’m super happy I bought it!

U50-T Great Watch

"U50-T Great Watch"

Verified Owner Comments: Love this watch. Sinn is extremely underrated in my opinion.

I own other tool watches from brands like Rolex, Omega & Breitling, but I can honestly say after receiving my Sinn U50, this is now my first true tool watch. this is the real deal. I love how simple and subtle the watch is paired with its amazing quality. Also the rubber strap is Premium quality and extremely easy to size.

Very satisfied with my purchase. My experience with watch buys was great as well. I really appreciated how they contacted me and confirmed my order and shipping address before sending the watch. Great costumer service. A+

Sinn U50-T Fully Tegimented

"Sinn U50-T Fully Tegimented"

Verified Owner Comments: Incredibly happy with this watch. Ultra durable and sits comfortably on the wrist.

Beautiful watch and strap

"Beautiful watch and strap"

Verified Owner Comments: This watch is gorgeous. Moving the bezel is extremely satisfying, the tegimented finish seems strong and looks great. The silicone strap is comfortable and looks great. All in all, I'd highly recommend this watch!

Very Pleased

"Very Pleased"

Verified Owner Comments: This is my second Sinn watch. I thought I'd try the silicone strap this time, and I am quite pleased. This setup seems appropriate for a dive watch. It is very comfortable, and the clasp works quite well. With my 7.5 wrist I was concerned that the U1 (44mm) might fit me better, but the U50 (41mm) looks just fine and is much thinner. I imagine the U1 would have been too chunky for me, so I am glad I went with the U50.

I tested the watch on my Weishi timegrapher, and right out of the box it was showing +2.5 seconds per day (average of 6 positions), which I consider to be excellent. Overall I am very pleased with this purchase!

Absolutely love it!

"Absolutely love it!"

Verified Owner Comments: Stunning craftsmanship and perfect size. Love it!

Delightful

"Delightful"

Verified Owner Comments: This face and band come together as a very subtle but solid combination of comfort and looks. I often only feel the watch there in the slightest of ways. Highly recommend it for a daily driver that looks nice any which way. Take your time sizing the band take it one notch at a time. As others have stated, the lumens could be a tad brighter, but they are still quite visible.

Great watch

"Great watch"

Verified Owner Comments: I am a structural engineer by profession and the metal used in the watch case as well as the Sinn tegimented metal treatment as opposed to applying a coating on the surface attracted me to this dive watch.

The watch is very substantial yet unpretentious. I truly enjoy the craftsmanship and built quality of it. It is also a wearable dimension without it being a bulky piece of metal on your wrist. True to its German DNA in every aspect of the design. Very satisfied.

Also extremely satisfied with the Watch Buys and their customer service. I received a call before shipping the material and a representative explained to me the product and their return policy and double checked everything was right, which I appreciated. Overall very satisfied.

Sinn U50

"Sinn U50"

Verified Owner Comments: Received this superb timepeice in a flash via first class customer service.

Perfect

"Perfect"

Verified Owner Comments: This is an amazing watch. It wears perfectly on my 7 inch wrist. It's thin and light, but has enough weight to feel very solid.

The fit and finish are extraordinarily well done. As a tool watch, the U50 has it all – extremely strong, light, thin, high WR, salt water resistance, magnetic resistance, low pressure resistance. Go anywhere, do anything (maybe not a wedding for some, but I'd wear it to one, goes under a shirt cuff easily at 11.5m thick).

Also, a quick note about the submarine steel. It appears to be incredibly strong (this version is fully regimented), and the matte gray look of it is perfect for this watch.

Sinn really nailed it with this one.

Glad I didn’t hesitate

"Glad I didn’t hesitate"

Verified Owner Comments: This is my first Sinn and I am extremely impressed.

The HODINKEE review caught my eye and convinced me to leave the Rolex/Omega groove I normally occupy. Give this watch some time and it will win you over with its rational design and utter functionality. Very wearable on my 7” wrist.

Superb finish and quite comfortable and top drawer customer service from Watchbuys. Treat yourself!
