This is the ultimate diver's chronograph watch - the brand new Sinn U1000 EZM 6 Chronograph.

The Sinn U1000 is designed to be virtually impervious to water penetration. The Sinn U1000 case is made from the same German steel that is also used in the construction of the outer hull of submarines. This submarine steel is not only extraordinarily sea water resistant (PRE value up to 38), it possesses also the highest anti-magnetic quality.

Next, the Sinn U1000 features a completely Tegimented case, pushers, bezel and crown. 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 has a hardness of 1,500 Vickers which is more than six times harder than standard steel. Further, the entire case resists the effects of exposure to salt water and salt water environments.

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.

This watch represents a breakthrough on the testing of chronograph functions at great depths. The watch is not only rated water resistant to 1,000 meters, the pushers and other chronograph functions have also been tested to that depth. Each Sinn U1000 watch ships with a certificate from the international testing lab Germanischen Lloyd certifying these tests. Sinn has developed a special system of double Viton® seals and other engineering processes to achieve this certification. While building a 1,000 meter dive watch is not in itself unique, building a diver's chronograph whose functions have been tested at that depth is an achievement.

The base movement is a top grade Valjoux 7750 which Sinn has modified to create their SZ-02 calibre. The primary modifications consist of a redesigned minute register which actually counts 60 minutes rather than the typical 30. This register has been enlarged and is placed at 6, with the primary hour register located at 12. Next, Sinn has used its special oil to construct the movement. The Sinn special oil, also known as Sinn 66-228, permits a greater range of operating temperatures from - 45º C to + 80º C - in other words, this watch will hold up in extreme conditions. To counter the affects of moisture and humidity, Sinn has applied their "Dry Hold" technology to this model, consisting of four copper sulphate capsules and the use of inert gasses sealed within the case.


Matte black dial with date at 9, Super Luminova on hands and markers complete the design. Other features include a sapphire crystal with anti-reflective coating, and silicone strap with tegimented deployant buckle.

This watch measures 44 mm by 18 mm.
