The Geneva-based manufacture makes a big splash at the SIHH 2015 launching a new collection called Harmony. In addition, the brand presented a duo which calibers’s parts are directly manually engraved. The Harmony line introduces a new cushion-shape case. This kind of shapes is a real challenge in terms of design as the round shape of the movement must fit harmoniously into a softened square (“cushion” as the angles are not sharps). The result involved a new know-how which is digital visualization to reproduce and enhance the reflects of light. This year is also a milestone for Vacheron Constantin because the brand introduces 3 new chronographs conceived and manufactured in-house and a fourth one (ladies’) which production was integrated. They are all present in the new Harmony collection, which includes also second time zones models for men and women. Actually , all Harmony pieces are in limited edition due to this important launch that celebrates also the 260th anniversary of Vacheron Constantin. Finally, the two Métier d’art mécaniques pieces integrate calibers are directly engraved, meaning each component was decorated one by one, and with a lot of care to avoid any distorsion that would impact its function.
