The sheer mechanical virtuosity of Caliber 1860

This bi-directional manual-winding movement composed of 727 parts that are meticulously adjusted, decorated and assembled by hand, called for more than 10 years of development. Hours, minutes, small seconds, grande sonnerie, petite sonnerie and minute repeater: its integrated construction requires considerable energy to enable the grande sonnerie to strike up to 96 chimes per day. Two barrels respectively provide a 72-hour power reserve for the movement and a 20-hour strikework power reserve in grande sonnerie mode.These advanced technical, acoustic and energy-related features make this sophisticated movement an accomplishment that is as unique as it is outstandingly complex.

Developed and manufactured by Vacheron Constantin

INDICATIONS

Hours, minutes, small seconds at 7 o'clock, grande sonnerie, petite sonnerie, minute repeater, indicator of grande sonnerie/petite sonnerie/silence strike mode selected via the bezel, movement power-reserve indication, strikework power-reserve indication

Key points

Simplicity and secure use

During time-setting, no chime can be sounded; and conversely, when chiming is in progress, time-setting is impossible until the watch has finished striking. No new chiming operation will begin so long as another one is sounding. The strike-mode security device ensures that when a change of mode is made while a chime is in progress, it will only be activated once the previous chime is complete. Finally, if the strikework power reserve is too low, the striking mechanism will not be activated, whether in passing or on demand.

Innovative strike-mode selection

The original strike-mode selection for the grande sonnerie, petite sonnerie and silence options is done via a 30-degree rotating bezel, thanks to a marker engraved on the side of the case and indicating the respective strike modes. The minute repeater is activated by a push-piece built into the crown at 3 o'clock, with the latter serving to rewind the movement in a clockwise direction and to charge the striking mechanism by a counter clockwise rotation.

Original construction

The final specific characteristic of Les Cabinotiers Symphonia is the fact that the striking mechanism – with its racks, feeler-spindles and snails – customarily positioned beneath the dial is in this instance visible on the back of the watch, through a transparent sapphire crystal caseback.

Design and finishing

The art of simplicity

The art of simplicity

The sobriety of the design highlights the complex mechanism of this horological feat housed within a white gold case featuring a customisable caseband.

A refined dial

A refined dial

Inspired by historical striking pocket watches from the Maison, the 18K gold silver-toned dial displays opaline, circular-brushed or snailed finishing, as well as baton-type white gold hour-markers and hands complemented by two black oxidised pointers.

Highly legible indications

Highly legible indications

Small seconds at 6 o'clock, the movement power-reserve indicator at 5 o'clock, together with the strikework power-reserve indicator at 2 o'clock pointed to by a serpentine hand, combine to create an impression of harmonious clarity and contemporary distinction.

A tradition of bespoke horology

Bespoke tradition

This one-of-a-kind model's case and dial, both of which may be customised in the Vacheron Constantin Les Cabinotiers department, reflect the tradition of excellence cultivated by the 18th century Geneva watchmaking artisans known as cabinotiers.
