A contemporary incarnation of a 1928 Vacheron Constantin chronograph, the new Chronograph in the Harmony collection clearly displays its kinship with the original model and pays it an eloquent tribute. Its generous pink gold cushion-shaped case reinterprets formal artistry firmly dedicated to technical refinement, since its three-dimensional construction houses the new hand-wound Caliber 3300 developed by Vacheron Constantin.
With this “all or nothing” system, the gears and cams cannot be set into motion without actually starting the mechanism, thereby considerably optimising the durability and reliability of the movement. Moreover, thanks to a new “friction” technique for the lateral coupling clutch, the chronograph seconds hand avoids the little jerk that tends to occur when the chronograph is activated.
In addition, the sliding-type lateral pusher ensures improved control of the chronograph functions.
With the aim of substantially enhancing the precision of the operational sequences, the chronograph uses two hammers instead of one for the start, stop and reset functions. Each exercises pressure on the heart-shaped cams, which turn in clockwise or counter-clockwise directions. The hands are thus brought back to zero. The hammers also return to their original place when the blocking-levers resume their initial position.
