Reaching for the Stars
If you’re a lover of complications then look no further than the Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication 3600, which is this year’s standout star and the most complicated wristwatch the 262-year-old ‘manufacture’ has ever created. In a nutshell, it’s a one-off 1 million USD 18-karat white gold oeuvre that took five years of development by a single VC watchmaker. With displays on the front dial, and the back, this 45mm watch features 514 parts and 23 (mostly astronomical) horological complications, providing time in three different modes: civil, solar and sidereal (each with its own gear train). Yet, despite all those specs (and presumably heavy draw) its thickness is just 8.7mm, and its power reserve is a mind-boggling 21 days. That really is an astonishing feat of engineering and it was achieved by the way of six mainsprings, all of which have been made from a proprietary alloy called ‘bioflex’.
