Damasko Swiss Valjoux 7750 Chronograph with a 60-Minute Stopwatch and 12-Hour Totalizer #DC56SIThe DC56SI is a Swiss Valjoux 7750 powered chronograph watch with a 60-minute stopwatch and a 12-hour totalizer function. The movement in this SI version features some upgraded parts and it has been regulated for accuracy in 5 positions. The stainless steel case size is 40mm diameter x 13.80mm thick. The case is bead blasted, hardened and finished with an abrasion-resistant Damest coating. It is also made with ice-hardened stainless steel. There is an integrated anti-magnetic inner cage to guard against the movement becoming magnetized.
The screw-down crown and mechanism is fully hardened and along with a screw-in case back, provides you with a 100-meter water resistance rating. A sapphire crystal with anti-reflective coating on both sides gives you increased clarity when viewing the black dial with white hands and markers. The hands and markers are also treated with long lasting CL1 SuperLuminova for reading the time in low light conditions. The day and date window is found at a special position slightly below the center axis. The DC56SI includes black leather strap with white stitching. 20mm lug width.
