The year 2012 marks a new breakthrough in the consolidation of the Overseas collection, Vacheron Constantin’s sporting and technical line. The Overseas Chronograph Perpetual Calendar model with its 18- carat pink gold case unequivocally establishes itself as the major reference in the collection, featuring a masterful blend of chic elegance and technical Haute Horlogerie.

The alliance between a chronograph and a perpetual calendar – two of the complications most favoured by devotees of mechanical Haute Horlogerie – confirm this new model as an embodiment of the proud tradition of excellence inherent to Vacheron Constantin.

This Overseas Perpetual Calendar model, boasting all the signature features of this collection, radiates a sophisticated, refined and immediately recognisable character – starting with the flowing and powerful lines of its case, the bezel inspired by Vacheron Constantin’s Maltese Cross emblem, along with the hour- markers, crown, screw-lock pushers, as well as the caseback enhanced by a raised medallion depicting the famous three-mast Amerigo Vespucci ship.

Its 18-carat pink gold 42 mm-diameter case, like all men’s Overseas models, is guaranteed water-resistant to 15 bar (approximately 150 metres) and houses a soft iron cage protecting the mechanical movement from magnetic fields of up to 25,000 A/m.

The association between the pink colour of the case and the subtle sandy shade of the dial lends a luxurious sporting touch to this model. Like the other timepieces in this collection, the hands and hour-markers are accented with white luminescent substance ensuring perfect readability even in the dark.

This exceptional model representing a compendium of technical Haute Horlogerie beats to the rhythm of Calibre 1136 QP and its 228 parts: a mechanical self-winding movement – just as one would expect from a sports watch – oscillating at the rate of 21,600 vibrations per hour and endowed with an approximately 40- hour power reserve. In addition to the hours, minutes and small seconds at 6 o’clock, Calibre 1136 QP powers the chronograph functions – sweep seconds-hand, 30-minute counter at 3 o’clock and 12-hour counter at 9 o’clock – as well as those of the perpetual calendar – day of the week, date, 48-month counter with leap years as well as a moon-phase display.

The Overseas Chronograph Perpetual Calendar is delivered with two straps: one in vulcanised brown rubber and the other in brown alligator leather. A pink gold triple-blade, double-pusher folding clasp guarantees security and comfort for the wearer of this exceptional model. This timepiece is also delivered with a luxurious presentation case equipped with a rotating mechanism that enables the watch – when not worn – to be kept perpetually wound and thereby ensure that the perpetual calendar indications are properly adjusted.
