Vacheron Constantin Thin Watch SIHH 2015: Harmony Ultra Thin Limited Ed.

Vacheron Constantin SIHH 2015 collection’s limited edition flaghip model, an Ultra Thin Grand Complication is limited to just 10 pieces! What’s special about it, you wonder? This Vacheron Constantin thin watch’s self-winding movement measures just 5.20 mm thick and its 8.40 mm cushion-shaped case. Perhaps, a new world record! Producing those 10 pieces, is a feat for Vacheron Constantin as it requires great precision and experienced craftsmanship in horology, to carve out and assemble such tiny fragments of a grand complication.

Equipped with a split-seconds function serving to time phenomena starting at the same time but of different durations, the new Harmony Ultra-Thin Grande Complication Chronograph by Vacheron Constantin is the slimmest in its category in terms of both its movement and its case. This Vacheron Constantin Thin watch SIHH 2015 is the first self-winding split-seconds Vacheron Constantin chronograph to bear the prestigious Hallmark of Geneva. It’s new in-house pays tribute to the aesthetic of the chronographs made for the brand in the 1920s, by reinterpreting the rounded shape and the interior angle bevelling of the bridges – that can only be done by hand – along with gold bushing and drop-shaped jewel surrounds.

The Ultra Thin Vacheron Constantin limited edition watch shown at SIHH 2015 boasts of massive 51-hour power reserve.

Dial Case Vacheron Constantin Thin Watch SIHH 2015: 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. The hours, minutes, small seconds at 9 o’clock and power reserve are clearly displayed on a luminous opaline silver-toned dial framed by a deep red tachometric scale. The blue-painted Arabic numerals beautifully match the blued chronograph hands, while elegant leaf-type hands punctuate the hours and minutes.

Caliber 3500 Vacheron Constantin 2015 Thin Watch: Development work on Caliber 3500 began in 2008, aimed at developing a chronograph movement. 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. Another particularly notable breakthrough is the blocking of the rotor when the barrel is sufficiently wound, thereby avoiding excessive tension in the winding spring. The creation of cone-shaped wheels improves the meshing of the wheels, thus giving the wearer the impression of softer, gentler winding. Moreover, the micro-technologies used for cutting the wheels have made it possible to create extremely close-set teeth to improve the engagement of the gear trains. The creation of an ultra-thin non-spherical differential has contributed to maintaining the power-reserve indication, without influencing the movement’s thickness. Finally, the development of a “dragging” chronograph minutes indication reduces the loss in amplitude and thus improves precision.
