Calibre Vingt-8


Calibre Vingt-8

This movement has a regulating organ that can be adjusted within extremely small tolerances. Similarly, a unique balance spring has been used whereby the outer tip has a typical Breguet overcoil while the inner end uses the lesser-known Grossmann curve.

The Vingt-8 is the first watch to have two escape wheels in such a configuration. This is a highly energy-efficient solution compared with traditional lever escapements, resulting in greater stability in day-to-day use.
