Product Details

The Sinn UX pushes watch technology to the limits. Like the Sinn U1 and U2 watches, the Sinn UX features a case made from the same submarine steel that is being used to build the latest generation of German military submarines.

The steel was procured by Sinn from a steel supplier to Emden GmbH, one of the North Sea shipbuilding yards in Germany which builds submarines from the very same steel. 

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.



Unlike the Sinn U1 and Sinn U2, the Sinn UX features a quartz movement rather than a mechanical movement.

By using this type of movement, Sinn is able to fill the watch with oil, which has the double 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.



The Sinn UX is covered with a thick sapphire crystal for extreme protection. This sapphire crystal features a special anti-reflective coating that is scratch resistant - the coating itself has been hardened to 1,800 HV.

The uni-directional ratchet operated rotating bezel is also milled from this submarine steel. The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths. The bezel features Sinn's Tegiment technology.

This watch is designed for operation in extreme temperature variations - it operates in temperatures between -20 and + 60 degrees Celsius.

The movement is water resistant to 5,000 meters, and the case is pressure tested to a diving depth of 12,000 meters as certified by Germanischer Lloyd in Hamburg.

Matte black dial with date at 3, Super Luminova on hands and markers, and striking red seconds hand complete the design.

This watch is fitted with a Sinn stainless steel H-Link bracelet with locking clasp (not quick adjust).

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 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.

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.

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.

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.

Service Notes for This Watch

This watch is powered by a quartz movement and the case is filled with oil.

Special proprietary machines and equipment are required to change the extended life battery and to refill the case with oil.

Because only Sinn in Frankfurt has the necessary machines and equipment to correctly service this watch, you will need to return the watch to Frankfurt approximately every seven years for service.

Amazing

"Amazing"

Verified Owner Comments: This watch exceeded all all my expectations. I currently own a Tuna and a Marathon JSAR though I love them all. The Sinn has become quickly my favorite go to watch. So much so I had to pick up a U1.

This watch looks great on a bracelet and strap. Just a fun amazing all around watch. You will not be disappointed with this purchase.

Also have to mention the great communication and customer service for Watchbuys! I will for sure be buying another watch from them.

Truly an Amazing Piece

"Truly an Amazing Piece"

Verified Owner Comments: Really in a class of it's own, the UX (outside of its amazing spec) is just a stunner. Been eyeing this thing for the better part of a decade and couldn't pull the trigger, but man I'm so glad I did and truly wish I'd done it earlier!

Clear and Accurate

"Clear and Accurate"

Verified Owner Comments: Where do I start? After 6 days it's gained about 1/2 a second. It's ultra visible from any angle, some people even think it's a smart watch because of the oil-filled case. It's so different than every other watch I own. There's no mistaking or faking what it is.

As a side note, I bought this model on the bracelet because the silicone model was not available, and I'm glad I did! I didn't know how much I would like this bracelet until I was forced to buy one (LOL). Definitely worth it. And to think the battery will last the better part of a DECADE!

Watchbuys customer service is second to none, as always. I ordered on December 23rd at 2:00am and got the next day (Christmas Eve) by 12:00 noon. 5-Stars.

Accurate and Legible

"Accurate and Legible"

Verified Owner Comments: . +: Quartz Movement = Accuracy . +: Oil Filled = Legibility . +: Large Dial = Legibility . +: Ample Lume = Legibility

Understated yet serious

"Understated yet serious"

Verified Owner Comments: Finally pulled the trigger on this watch after a lot of homework online and youtube. Not disappointed. Similar to the professionals this watch was designed for, it does not scream look at me!. This watch has a silent confidence. It wears well on my close to 8 inch wrist and in my opinion could be worn at a barbecue with a polo shirt, or with a sport jacket and slacks. Most customers will not require all the qualities engineered into this watch, but its really cool to have )

Watchbuys was very professional and prompt. . Excellent communication. If your on the fence about buying this watch, go for it. No buyers remorse.

Love it.

"Love it."

Verified Owner Comments: I love this watch. It's good looking, accurate, and full of cool tech. Highly recommended!

What I wanted

"What I wanted"

Verified Owner Comments: In this case I wanted a lower maintenance quartz watch and this passes the test perfectly, and it is deadly accurate too.

So coveted

"So coveted"

Verified Owner Comments: My friend saw this on my wrist and immediately offered me tickets to the Halloween party at the Playboy Mansion for the watch.

I declined but knew that I had a fantastic watch!
