The flagship model in this collection, the Overseas Chronograph is given a new expression this year with this steel variation enhanced by a deep blue dial. With its caseback distinguished by a raised motif depicting the historical Amerigo Vespucci sailboat, this Haute Horlogerie chronograph echoes all the distinctive codes and characteristics which, right from the time of its launch in 1996, have contributed to forging the strength of this technical and sporting line. Witness its famous bezel inspired by the Maltese Cross, its crown and its screw-lock pushers, its soft iron cage protecting the mechanical movement from magnetic fields of up to 25,000 A/m, as well as its case that is water-resistant to 15 bar (around 150 metres). Another distinctive feature is the particularly supple and comfortable steel bracelet – inseparable from any genuinely sporting watch – with its links shaped like a half Maltese Cross.

An object of fascination due to its complex mechanism – reflecting both the sporting spirit and precision timing performance – the new Overseas Chronograph model is distinguished by its deep blue dial with meticulous finishing, enhanced by luminescent hands and hour-markers guaranteeing perfect readability. The refined and elegant 42 mm-diameter cases houses Calibre 1137, a mechanical self-winding chronograph movement comprising 183 parts, endowed with a 40-hour power reserve and beating at the frequency of 21,600 vibrations/hour. In addition to the hours, minutes and small seconds at 6 o’clock along with the chronograph functions – sweep seconds-hand, 30-minute counter at 3 o’clock and 12-hour counter at 9 o’clock – this Overseas Chronograph watch features a large date appearing through a twin aperture at 12 o’clock.

Clearly dedicated to both technical sophistication and aesthetic elegance, this new Overseas Chronograph model from Vacheron Constantin strengths the enviable stature acquired by the Geneva-based Manufacture in the field of Haute Horlogerie sports watches. It once again demonstrates that mechanical complexity can work wonders when it is combined with iconic design.
