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 bracelet 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 fully Tegimented Sinn stainless steel H-Link bracelet.

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.

Sinn U50 T

"Sinn U50 T"

Verified Watch Owner Comments: Good looking watch. The watch itself wears well and is very high quality. Runs a few seconds fast per day. The bracelet was difficult to get sized just right. I wish it had better micro adjustment.

Bought the olive grey textile Sinn strap, which has been on the watch since day 1 and suits the watch very well. Despite fumbling around trying to get the textile strap on, there are no scratches on the lugs. The tegiment seems to be more than marketing hype.

First Sinn watch. Won’t be my last. Overall very happy with the watch.

Best Diver's Watch

"Best Diver's Watch"

Verified Watch Owner Comments: My U50 Tegimented watch has the tough pedigree and reliable accuracy of a go anywhere do anything watch. The U Boat steel has a warm smooth tactile feel that has to be experienced to be appreciated.

The U50 is a subtle, time at a glance tool watch that efficiently does its job. It is thin for a diver's watch and that speaks to the great wearability. One the favorites of my collection.

Sinn U50 - Exceeded Expectations

"Sinn U50 - Exceeded Expectations"

Verified Watch Owner Comments: This was my first Sinn watch, first purchase from WatchBuys and first purchase of any watch online. The watch and process exceeded my expectations. Trey was very helpful in selecting a delivery date when it was convenient for me to be home. The watch arrived in perfect condition.

It has a very solid and high quality feel, similar to a modern Rolex. The size is perfect for my 6.75 inch wrist. It's running +4 seconds per day which is as good or better than my METSAS certified Tudor BB Ceramic. It's amazing how Sinn achieves 500m of water resistance in such a slim case. It wears very well under tight shirt cuffs, sweaters and jackets.

The bracelet is very good. I do not understand all of the fuss about the clasp. It works fine and is comfortable. Another couple micro adjustment holes would be nice, but after trail and error I got the right combination of links and holes to fit the watch to my satisfaction. This will not be my last Sinn.

What Happened...?

"What Happened...?"

Verified Watch Owner Comments: The U50-T Makes me feel guilty for not exposing it to the extreme conditions it was designed for. The feel is so solid and impervious that I find myself taking it off every once in a while just to enjoy the hefty nature of this instrument. The bezel is unusually pleasurable with its reassuring snug engagement. The crown feels and threads competently. The wind is smooth and effortless.

The lume is visibly active the entire night. Timekeeping is within chronometer specs. The H-link bracelet is notably comfortable with an impressively substantial feel. So my question to Sinn is, What happened with the Clasp?! This Tinny stamped clasp does not belong on this high quality instrument. To the Good Folks at SINN: Please develop a sturdy milled replacement clasp worthy of this marvelous timepiece - For the love of all that is German Engineered.

Other than that, I am extremely happy with my purchase of this watch, and the excellent communication and service from WATCHBUYS.

Excellent Tool Watch!

"Excellent Tool Watch!"

Verified Watch Owner Comments: I love this watch! It looks great and is keeping excellent time. The hands are easy to read at any angle, and the bezel is nice and firm. A quick pass with my flashlight made the lume last for a couple of hours. Very happy with this purchase.

5 Stars

"5 Stars"

Verified Watch Owner Comments: Perfect tool watch that filled with German DNA. Very special watch with amazing capabilities. Low key and underrated, when people see you wearing this watch will definitely know you're a watch enthusiast. It's brilliant.

Sinn U50-T

"Sinn U50-T"

Verified Watch Owner Comments: This watch is the perfect tool watch.

Awesome watch.

"Awesome watch."

Verified Watch Owner Comments: I love this watch. Only four out of five stars though, as the lume (which is acceptable) should be better for the price. It's keeping COSC standards for time, and looks GREAT. It's my new daily wearer. I am not afraid to wear it.

If I hit a doorknob with this watch, I have to check the doorknob to make sure that the door still works! The watch is built like a tank and masculine, yet classy and small enough to wear anywhere. Buy it.

New Favorite

"New Favorite"

Verified Watch Owner Comments: Aging eyes and presbyopia led me to search for the most legible analog watch. I am not disappointed as I can easily read the time on the U50 without glasses. The tegimented case and bracelet are quite beautiful and have a very pleasant, smooth, silky feel unlike other higher end watches in my collection.

The bracelet is excellent for me and fits my 6.75 inch well with the removal of two links. This is my first watch with a Sellita movement which caused some degree of concern however, the SW300 is an excellent timekeeper and is running consistently at about +1-2 SPD over the last three weeks.

In form and function, this watch is a bargain and I believe it competes with watches at a significantly higher price point. The U50 also has the cool factor that can not be denied. Enthusiastically recommended.

Perfect yet bittersweet

"Perfect yet bittersweet"

Verified Watch Owner Comments: No watch enthusiast is the same or values the same qualities in a watch. I will say though that this watch is completely perfect for me as an everyday watch. Equal parts beautiful and useful. It’s bittersweet though as I have neglected the rest of my collection for weeks since buying this.

It may be the novelty but I will say the saying of "buy once cry once” applies to this watch. It is objectively expensive, but I have six other watches that don’t get worn because of how much I love this one…aside from a gshock for heavy duty working. Save your money and get this, you won’t regret it.

Most versatile watch ever!

"Most versatile watch ever!"

Verified Watch Owner Comments: If you are looking for robust watch, the Sinn U50-T will be the one for you. It is my second Sinn watch and also second purchase from Watchbuys. I've satisfied with my two Sinn watches, U50-t and 556i-m.

This German watch and purchasing experience from Watchbuys won't disappoint you.

Fantastic Size, Fit, and Finish

"Fantastic Size, Fit, and Finish"

Verified Watch Owner Comments: I have been eying this wonderful piece of technology for some time now. As an owner of a U1, I am familiar with the capabilities, look, and feel of these watches, but always thought the U1 was a little large for my wrist.

As soon as I opened the box for the U50 I was amazed at how it looked, so much better in person. At 41mm, this is a perfect size and actually fits me a little smaller than expected. I believe this is a perfect size, and if SINN were to make a few other models in this size, my collection would grow. After 3 consecutive days of wearing, I am at +8s/day. Well within tolerance.

Thank You SINN for a quality product that will hopefully last a lifetime.

Great Watch But...

"Great Watch But..."

Verified Watch Owner Comments: Love the watch. It's a perfect size for my 7 wrist. However, the bracelet color doesn't really match the color of the watch. Apparently, the Submarine steel of the case takes the Tegimenting process differently than the regular steel of the bracelet. Why can't they make the bracelet out of Submarine steel too?

A Man’s Watch

"A Man’s Watch"

Verified Watch Owner Comments: I love my Sinn U50T on bracelet! I have always admired German engineering and quality. The watch has a strong presence on the wrist with its industrial looking grey tones much like titanium. It’s not one for the ladies as it presents a masculine appeal. Sinn is getting much wrist time among my extensive collection.

Sinn U50-T

"Sinn U50-T"

Verified Watch Owner Comments: I am very pleased with my purchase experience through WatchBuys. It was a seamless process from start to finish. I spoke to a rep with several questions and was very impressed with the reps knowledge of the product.

I love the watch and after about two weeks it’s running at plus two seconds a day so well within chronometer standards. The Tegimenting seems to be worth the extra cost. The shipping was fast. Im very happy.

U50-T on Bracelet

"U50-T on Bracelet"

Verified Watch Owner Comments: Nice watch, keeps great time (+1spd). Definitely recommended.

Shipping was fast, will purchase from Watchbuys in the future.

Beautiful watch, but not perfect

"Beautiful watch, but not perfect"

Verified Watch Owner Comments: Overall, this is a beautifully made piece. The tegimented steel is durable and feels silky and fantastic. The proportions are classic and functional. Unfortunately, the lume is poor at best and that is disappointing.
