#SIHH 2017: Vacheron Constantin Les Cabinotiers Celestia Astronomical Grand Complication 3600

Les Cabinotiers Celestia Astronomical Grand Complication 3600 9720C-000G-B281

This is another super complication developed and manufactured by the Geneva watchmaker founded in 1755. Click on “read more” and come dream with me …

 

So what shall I write when seeing this timepiece? Such masterpieces are rare and unique and in these stormy weather in some way politically not really correct, since what the watch industry needs now again are more, more, more affordable products. Even Vacheron Constantin needs them! Sorry guys, It must be said!

But still such masterpieces are necessary to keep the dream alive, to show to what extend the industry is able to push the limits. The new Les Cabinotiers Celestia Astronomical Grand Complication 3600 simply is a stunning watch and very expensive in fact. The watch is issued in a limited edition of one …

Les Cabinotiers Celestia Astronomical Grand Complication 3600

More than twenty essentially astronomical complications appear on the front and back dials of the watch, providing a reading of time in three modes – civil, solar and sidereal – each driven by its own gear train.

The new Calibre 3600 is a remarkable feat of miniaturisation and engineering. It comprises 514 parts while measuring just 8.7 mm. Calibre 3600 controls 23 functions and has a three-week power reserve. It is yet another vivid demonstration of the technical expertise cultivated by Vacheron Constantin in the field of astronomical complications.

On the front, the slate grey dial reveals 15 artfully arranged complications. As well as readings of civil and solar time (running equation of time) by three coaxial hands, it also has a perpetual calendar with a precision moon phase as well as a remarkable mareoscope composed of a tide level indicator and a 3D depiction of the Earth-Moon-Sun alignment. Tides are governed by physical laws and depend on the gravitational attraction and centrifugal forces of these three heavenly bodies.

To measure and display the difference between civil and solar time, this timepiece is equipped with an equation of time mechanism. Moreover, the latter is also a ‘running’ equation of time, a kind rarely seen in wristwatches and indicating solar time by means of an additional coaxial pink gold minutes hand adorned with a cut-out sun.  The running equation of time is far more complex to create and enables instant readings of solar and civil times. To ensure exactitude and precision, Vacheron Constantin has adjusted it to a tropical gear train simulating the tropical year, meaning the time the Earth takes to make a full turn around the Sun and corresponding to 365.2421898 days.

Representing a ‘memory’ of time yet to come, a perpetual calendar is able to keep track of the irregularities of the Gregorian calendar with no need for any intervention other than a date change every 400 years. It displays the day of the week, the month and the leap- year cycle through apertures, while pointing to the date with a serpentine hand. The precision moon-phase display requires a one-day correction only once in 122 years.

On the back of the watch, a second dial is also brimming with worthwhile astronomical functions. Composed of two superimposed sapphire discs, it is distinguished by its limpid, airy design as well as the originality of its translucent celestial chart for which a patent has been filed. In the foreground, this display depicts the constellation viewed from the Northern Hemisphere, ringed by an anthracite inner bezel ring showing the months of the year as well as a gauge-type power-reserve indicator. On this same transparent disc, two ellipses – one red and the other white – respectively correspond to the projections of the ecliptic and the celestial equator.

The Calibre 3600 has an extraordinary three week power reserve ensured by six barrels, coupled by three. The resulting ensemble is a true feat of miniaturization comprising as already mentioned 514-part finely adjusted and decorated parts and measuring just 8.7 mm thick! This mechanism, equipped with a tourbillon featuring a large balance wheel for enhanced precision and regularity, fits neatly inside an elegant 45 mm-diameter white gold case.
