Calibre 1003, that tops the list of the most beautiful and refined ultra-thin movements ever created, has been challenging mechanical laws for more than 50 years.
The process of the movement production is extremely sophisticated and the most highly qualified Vacheron Constantin specialists are responsible for its adjustment.
The redesigned version of the caliber is still the slimmest movement available, with its 1.64 mm thickness and 21.10 mm diameter.
The finishing of the caliber has become even more refined, with its bridges and mainplate sculptured from 18K gold. The 117-part movement operates at a frequency of 18,000 vibrations per hour. The tiny movement provides more than 30 hours of power reserve.
Calibre 1003 boasts an extremely meticulous decoration, with hand-performed Cotes-de-Geneve, bevelling and chamfering, as well as the steel parts drawn with a file. The movement with such supreme finishing is crowned by the prestigious Hallmark of Geneva, a certification guaranteeing the origin, precision, fine craftsmanship and durability of the movement.
Calibre 1003 is housed by a round watch crafted in 4N 18K pink gold. The timepiece, 36 mm in diameter, has been suggested by one of the three historical watches that appeared in 1955, reference 4961.
The new watch demonstrates an even slimmer 4.1 mm case – at the moment the thinnest mechanical hand-wound watch ever created. It is 30-metre water-resistant. It incorporates a transparent sapphire crystal case-back and a titanium casing circle. It will be premiered in 2010.
In 2010, Vacheron Constantin will unveil one more watch, paying homage to its ultra-thin timepieces. It will be a square-shaped watch, inspired by the model, reference 7614, released in 1968 and animated by the renowned ultra-thin self-winding Calibre 1120. The timepiece will join the brand’s Historiques collection.
The new Vacheron Constantin watch is created with updated technical features. It is 30-metre water-resistant. It incorporates a sapphire crystal and a clipped-down solid case-back the same as the original model.
The timepiece measures 35.2 mm along its sides and is even thinner than the 1968 model it is based on – it has a 5.5 mm thickness compared with a 6.52 mm thickness of its predecessor. In fact, it is on the list of the thinnest watches in its category. The timepiece is also animated by the ultra-thin self-winding Calibre 1120.
The exceptional movement boasts a sophisticated construction, being based on a number of unusual technical solutions.
For the new version of the 1968 watch, Vacheron Constantin has rebuilt Calibre 1120 – the movement has maintained its dimensions, its 28 mm diameter and 2.45 thickness, but now it incorporates an 18K gold oscillating weight with the Maltese Cross system. It gives an advantage of a 40-hour power reserve.
