Ressence Type 7

The Type 7 shows the time with rotating discs on a single convex dial rather than hands, and it is wound and set through the caseback rather than a crown. The upper of its two sealed chambers is filled with 2.95 ml of oil. The ROCS 7 display adds a GMT, a 120-second runner that doubles as a shock indicator and an oil temperature indicator shown by colour, driven magnetically from the dry movement below into the oil, with bellows to compensate for expansion. The case, dial and bracelet are Grade 5 titanium, 41 mm across and 14 mm thick with a fixed ceramic bezel and double-domed sapphire, rated to 50 m. It runs 36 hours and weighs 123 g on the bracelet.
