Moreover, Calibre 3200 employs the same novel technology and 65-hour power reserve as its two counterparts in the Harmony collection. It has a lateral coupling clutch with reduced friction that prevents lag. Additionally a “dragging” 45-minute chronograph function is configured to prevent motion in the gears and cams without sufficient pressure applied to the pusher (call it preventative maintenance).

Technical merits aside, Calibre 3200 is masterfully finished, not only with Côtes de Genève, dressage, and beveling, but also with a gold bridge that is hand-engraved with Fleurisanne Arabesque. And check out that Maltese Cross-shaped column-wheel screw!

The Harmony collection overall is a showstopper and the new Harmony Tourbillon Chronograph is no exception. This model will be limited to 26 pieces in 950 platinum, each individually numbered, with a list price of $314,600.
