Product Details

The Sinn U1 Series has become the best selling in the brand's history and is recognized as iconic to the brand.

The Sinn U1 SE changes the original design of the classic Sinn U1 by adding a fully Tegimented DLC black case and a new dial, bezel and hands, which feature SuperLuminova in an ivory color.

The result is a watch that is a bit more subtle in design as the watch uses no red as in the standard Sinn U1.

The Sinn U1 SE Black on black silicone strap features the same great case design made in-house from German submarine steel at Sinn's case making facility in Glashutte, Germany. Once the case is complete, the Tegimenting process begins, and when we say "fully Tegimented" we mean what we say - case, crown, bezel, case back and even the anti-reflective coating.

The combination of the submarine steel and fully Tegimented case create superior scratch and corrosion resistance. 

And unlike watches made in stainless steel, the watch case does not need to be rinsed with tap water with each exposure to a salt water environment since it is made from true submarine steel.

The uni-directional ratchet operated rotating bezel is also milled from this submarine steel 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 international testing lab of Germanischen Lloyd has tested the Sinn U1 SE on rubber strap, and determined that the watch can be certified as water resistant to 1,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

Features of This Watch

Matte black dial with date at 3, ivory SuperLuminova on hands and markers, and the same ivory color is carried over to the bezel.

Other features include sapphire crystal with anti-reflective coating, and black locking clasp which is hardened using the Tegiment process.

  • Shock resistant in accordance with DIN 8308
  • Anti-magnetic in accordance with DIN 8309
  • Water resistant to 1,000 meters
  • 44 mm case diameter
  • Screw down crown
  • Meets the professional diving requirements of DIN 8306
  • Low pressure resistant at high altitudes
  • Screwed bezel which won't detach upon impact

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.

Second Sinn Watch Purchase

"Second Sinn Watch Purchase"

Verified Watch Owner Comments: Very happy with my latest purchase. Great watch, speedy delivery and great customer service !! Thanks to all at WatchBuys

Durable, beautiful crystal

"Durable, beautiful crystal"

Verified Watch Owner Comments: I had wanted a U1 for a long time, love the moser look. I have been impressed with the black treatments durability. Also the crystal and anti reflective treatment is amazing. I would highly recommend this Sinn!

So glad I finally joined U1 club!

"So glad I finally joined U1 club!"

Verified Watch Owner Comments: I originally tried on the U1 in their Frankfurt boutique. I could tell instantly that it was precisely made and of high quality materials. Over the years, I've been looking at the watch again and again, and when the SE model came out, it really filled a gap in my collection. Now I have it and its the first watch I've purchased that I like even more in person and on my wrist than in reviews and photos. It wears so comfortably, almost small considering the 44 mm case size. Its fits well under shirt cuffs and is easy to wear. I wish the lume was a bit brighter, but I'm used to the chroma light lume on my Explorer II which is bright! The quality and comfort of the silicone bracelet is extraordinary. The deployant clasp works well and there is space for two length adjustments for wrist swelling or wetsuit use. I love this watch and my only regret is not buying it sooner! I also should note I had a very good experience purchasing from WatchBuys. I was on a waitlist for the watch and rece... - more details

U1 Love

"U1 Love"

Verified Watch Owner Comments: I've had this piece for a couple of weeks now, I've worn it every day since receiving it. I bought this for daily wear...dare I say a beater/tool watch? I do farm/ranch work daily and wanted something robust. Well, I got it. Rubber strap is super comfy. I worried about the buckle not having a fold over's not a worry anymore. The buckle stays solidly latched (and I bang around a lot) Other PVD watches I've had would already show marks/scratches, not a mark on this watch case or buckle so far.

Size is perfect! sits nicely on the wrist. Bezel rotates with solid clicks, no rocking or wiggles. Lume is awesome and bright. Best part... it's keeping perfect time, no need to adjust. Ya, it's only been two weeks or so but I'm impressed with it being spot on for that amount of time. Branding calves, irrigation work, field planting and harvest, hunting, boating, camping, bring it on! This watch is up to anything!

Another winner!

"Another winner!"

Verified Watch Owner Comments: This is my 4th U1 and they are all splendid! The dial on this one is unique and attractive. As with all Sinn watches I have, it is within a few spd timing. Be careful cutting the rubber strap to fit, and you will have a wonderful and substantial that will serve you well for years!
