Vacheron Constantin once again challenged its most experienced master watchmakers to create an extremely sophisticated Grande Complication wristwatch equipped with an exceptional set of functions. They took on this terrific technical challenge to create a one-of-a-kind model, Maître Cabinotier Astronomica.
This impressive feat of miniaturisation, driven by a manual-winding Calibre 2755-B1, brings together 15 of the most demanding horology complications and gives pride of place to astronomical functions. It is also the very first representative of a new and highly exclusive range of models crafted in the spirit of Geneva’s 18th-century cabinotiers, combining exclusive production with personalisation and masterful accomplishments.
This exceptional movement, embodying a compendium of horological excellence and bearing the prestigious Hallmark of Geneva, is housed within a white case 19.1 mm thick with a 47 mm diameter. Inspired by the world’s most complicated wristwatch, which paid eloquent tribute in 2005 to the 250th anniversary of the Geneva-based manufacturer’s famous Tour de l’Ile, the unique Maître Cabinotier Astronomica once again demonstrates the remarkable expertise Vacheron Constantin has acquired in combining multiple complications within an extremely small space.
Boldly reaching for the stars, Calibre 2755-B1 is one of the most complex timepieces ever made by the manufacturer and features a number of unusual – mainly astronomical – complications. This mechanical, manual-winding movement with 58-hour power reserve offers an original combination of 15 complications driven by 839 parts.
