Base movement: 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 - 45є C to + 80є 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.

Dial: Black

This watch features a brand new bezel design from Sinn. First, the bezel is attached to the watch with screws rather than friction mounted. These screws prevent the bezel from becoming detached through accidental contact with other objects. Next, the bezel is locked in place and will turn only if downward pressure is applied. This "lock and push" system ensures that time sensitive events (such as dives) will be correctly measured.

Water Resistance

Next, a discussion of water resistance. 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 S 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.
