Celebrating the 260th anniversary of the manufacture, Vacheron Constantin unveiled a new line of luxurious timepieces, the Harmony Collection at SIHH 2015 luxury watch exhibition. The flagship model of this new collection, presented in a 10-piece limited, numbered edition, the new Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin immediately makes its mark in the field of ultra-thin horology by setting a new world record with its self-winding movement measuring just 5.20 mm thick and its 8.40 mm cushion-shaped case.
Mounted on ball bearings, this unusual construction provides a perfectly clear view of Caliber 3500, entirely hand-decorated in keeping with the noblest watchmaking traditions. This peripheral structure also serves to preserve the exceptional slimness of the world’s thinnest self-winding split-seconds chronograph movement. To signal its membership of an exclusive series dedicated to the 260th anniversary of the Manufacture, the peripheral oscillating weight of the Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin bears the dedicated scrolling pattern specifically created by the brand’s designers for this occasion. This unusual motif, also known as “fleurisanne engraving” is inspired by the arabesques adorning the balance-cock of the oldest pocket watch from the Maison, signed by Jean-Marc Vacheron in 1755.
Development work on Caliber 3500 began in 2008, aimed at developing a chronograph movement featuring a traditional kind of architecture, while benefiting from cutting-edge technologies in order to offer reliability, user friendliness and perfect visualisation of the movement aesthetic. This caliber benefits from the numerous advanced features designed by the Manufacture’s development team, including the so-called “friction” technique for the lateral coupling clutch, which serves to reduce a potential jerk of the hand when the chronograph starts running.
Housed in a precious cushion-shaped case made of 950 platinum, Caliber 3500 deserved an exterior to match its excellence. The “shape-in-a-shape” case combining a curving case, a square waisted case middle and a circular bezel creates a sensation of slenderness, while demonstrating an entirely unique and impressive character.
