The Les Cabinotiers Celestia Astronomical Grand Complication 3600 is a prominent model in the modern day, grand complication watches created by Vacheron Constantin. One fine example among them is the Reference 57260 – the world’s most complicated watch equipped with 57 complications created for the 260th anniversary of the Manufacture in 2015.
Featuring an all-new construction, this mechanical masterpiece follows in the eminent wake of a unique creation representing a milestone in the history of mechanical horology and laying a veritable cornerstone for new watchmaking feats by Vacheron Constantin. The one-of-a-kind Les Cabinotiers Celestia Astronomical Grand Complication 3600, which boasts 23 complications on its twin dials; provides a combined view of civil, solar and sidereal times by means of three separate gear trains.
A remarkable feat of miniaturisation and engineering, the new Vacheron Constantin Caliber 3600 – an integrated movement comprising 514-part while measuring just 8.7mm thick – controls more than 20 functions and has a three-week power reserve. It is yet another vivid demonstration of the technical expertise cultivated by the Maison in the field of astronomical complications.
Epitomising the peak of horological mastery, this unique timepiece equipped with a wealth of astronomical complications united within an incredibly small area represents an impressive sum of knowledge, calculations and fine adjustments. Its captivating functions notably feature the triple-time civil, solar and sidereal displays powered by three distinct gear trains, including a “tropical” gear train dedicated to all the solar functions.
This unique creation features a doubled-sided display of 23 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.
The fascinatingly elegant precision moon-phase display requires a one-day correction only once in 122 years and is read off by means of two superimposed discs bearing a laser-engraved true image of the full moon, a day/night indication and the age of the moon – meaning the number of days elapsed since the last full moon. These precious functions are complemented by sunrise and sunset times, pointed two by slim hands moving over two graduated scales, as well as the length of day and night appearing on a special gauge at 6 o’clock. This set of complications that occur but rarely in the Fine Watchmaking sky is further enriched by other captivating indications arranged in a semi-circle: zodiacal signs, seasons, solstices and equinoxes. Solstices – at which the day is at minimum or maximum length – occur twice a year in summer and winter; whereas equinoxes – when day and night are of equal length – correspond to the start of spring and autumn.
The extremely complex and exclusive Caliber 3600 powering this exceptional watch called for five years of development, from the start of its fully integrated conceptualisation through to the finishing touches on its refined exterior. This mechanical manual-winding movement not only achieves the feat of combining more than 20 horological complications – including three distinct times driven by three dedicated gear trains – but also has an extraordinary three-week power reserve ensured by six barrels, coupled by three. It naturally takes considerable energy to ensure that such an impressive number of astronomical indications operates with all due precision.
Presented in the collection Les Cabinotier, made of exclusive timepieces, this astronomical supercomplication model exemplifies the tradition of Geneva’s 18th century “cabinotiers”. These highly specialised watchmaking artisans in their attic workshops created authentic bespoke masterpieces intended for prestigious clients around the world. Fired by the same spirit of blending horological prowess with exclusive service and extreme personalisation, Vacheron Constantin perpetuates this same philosophy of excellence.
The quintessentially rare Les Cabinotiers Celestia Astronomical Grand Complication 3600 is issued in a limited edition of one. Fitted with an alligator leather strap secured by a white gold pin buckle, it comes in a luxurious presentation box adorned with wood marquetry.
