This sporty chronograph with a calendar has a seifwinding column-wheel movement. It measures time to the tenth of a second, totalizes the hours, minutes and seconds on three counters, and features an operating reserve of 50 hours. Its screw-down crown gives it water-resistance to 30 m, and its meticulously hand-decorated movement can be admired through the transparent sapphire back of its 18K gold or stainless steel case. Available with a silver, pink or anthracite dial, this watch comes with a sharkskin or genuine crocodile strap.
