Product Details

The Sinn U2 EZM 5 Schwarz (Black) has become one of our best selling watches and for good reason - it's tough, packed with technology and looks great on your wrist.
All Tegimented
This watch is far more than simply a black version of the standard Sinn U2. When Sinn first introduced the U Diver's Series several years ago, the most requested feature was an all Tegimented watch (the standard U models feature a Tegimented bezel).
After the initial U Series was released, Sinn began development of two watches that featured a Tegimented bezel, case, crown and case back, the first of which is the Sinn U1000 and the second this watch.
The Sinn U2 Black is constructed from the same steel that is used on the outer hull of submarines. The steel was procured by Sinn from a steel supplier to Emden GmbH, one of Germanys North Sea shipbuilding yards who construct 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.
Next, the Sinn U2 Black features a completely Tegimented case, bezel, crown and case back. 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 layer on this watch in combination with the PVD coating has a hardness in excess of 2,000 Vickers which is more than nine times harder than standard steel.
The Tegiment layer 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. This process increases the submarine steel's resistance to corrosion, as well as provides extreme protection from scratches and other damage to the case.
Engineering and Technology
The technology and design elements used to create the new Sinn U2 Black go far beyond standards used at most watch companies.
The Sinn U2 Black contains features you won't find in other watches:
- Full Tegiment construction
- Bracelet is black PVD and Tegimented
- Case constructed of submarine steel for superior resistance to corrosion and scratches
- Double Viton seals
- Two Sinn copper sulphate capsules to absorb moisture and humidity
- Inert gasses have been inserted into the case to promote a dry and stable environment
- Bezel is screwed to the case using an exclusive Sinn design
- Built to the standards of the German special forces - EZM 5
- Second time zone complication indicated by a red tipped hour hand
- Double coated anti-reflective sapphire crystal hardened with Tegiment process
- In house case construction from Sinn's Glashutte case manufacture
- Increased water resistance to 2,000 meters
- 4.6 mm thick sapphire crystal
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 international testing lab of Germanischen Lloyd has tested the Sinn U2 Black, and determined that the watch can be certified as water resistant to 2,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.
Bold New Look
This is a watch with "attitude". The new black case design and black bezel are all Sinn, and present an almost "stealth" appearance.
And this watch has to perform - it's part of the EZM family of watches.
Sinn is known for their professional special forces watches, called the Einsatzzeitmesser (EZM - in English "Mission Timer") series. Sinn has long been a supplier of watches to various divisions of the German special forces, including the GSG-9, border protection, customs, military and special police divisions. Designing watches for these units carries a number of requirements, including resistance to shocks, water, magnetism and temperature changes among others.
