Formex Essence Automatic Chronometer Silver 0330.1.6341.713

It runs on a self-winding Sellita SW200-1 that COSC certified as a chronometer, with a date and a 38-hour power reserve, shown through a sapphire caseback. The Chronometer's dial is vertically brushed rather than sunray, with machined indexes and faceted, lume-filled hands. The 43 mm steel case, 10 mm thick, carries Formex's patented Case Suspension System, which absorbs shocks before they reach the movement and lets the case flex with the wrist.

The watch head is the same as the silver Chronometer on bracelet (0330.1.6341.100) and on rubber (0330.1.6341.910); only the final block of the reference, the strap, changes. The lugs take a 22 mm strap, and the straps use a tool-free quick-change system. The Essence Automatic Silver on calf (0330.1.7341.722) is the version without the COSC certificate and with a sunburst dial. The black (0330.1.6321.722), blue (0330.1.6331.722), brown (0330.1.6351.722) and grey Dégradé (0330.1.6324.713) Chronometers on calf differ from this one only in dial colour.
