Les Cabinotiers Symphonia Grande Sonnerie 1860

In Context

At 45 mm it is a large watch — well above this catalogue’s 40 mm median, and enough to dominate a narrow wrist. At 13.6 mm it is a tall case, and it will catch on a cuff. The sapphire crystal will resist everything short of deliberate abuse.

The movement is hand-wound, so winding it becomes part of the day rather than something the watch does for you. 72 hours of reserve puts it well past a weekend — several days off the wrist and it is still going. At 21,600 vph the seconds hand advances 6 times a second, the slower and more audible rate of an older design.

9200E/000G-B099 stands on its own in this catalogue — no other reference here shares its base number. It pairs a silver dial with a white gold case. It was a limited edition. Introduced in 2017.

Caliber 1860 was introduced in 2017. This hand-wound movement is the first Grande Sonnerie made by Vacheron Constantin. It consists of 727 parts including 74 jewels, and measures 37mm across at a height of 9.1mm. The power reserve for the movement is 72 hours, while the strike work has a power reserve of approximately 20 hours.
