GMT-6 ONLY WATCH

WATCH DESCRIPTION
The movement contains a proprietary sprung-balance system that ensures perfect timing of the watch according to strict tolerance criteria. The balance has four gold inertia-blocks to adjust the daily rate.
To equip this exceptional timepiece, a unique and very rare balance-spring system has been used. The outside is a typical Breguet overcoil, while the inner terminal follows the less common Grossmann principle.

The watch’s outstanding feature is its escapement; it is the first watch to present two escape-wheels in such a configuration. The escape-wheels provide a direct impulse to the balance through the roller/jewel. This escapement is extremely efficient and requires less energy than traditional lever escapements, offering gains in terms of longevity and stability in everyday use.

The sublimely elegant balance-cock offers an unobstructed view of the escapement and balance. It also allows the enthusiast to admire the synchronised movements of the escape-wheels.

A GMT mechanism is integrated in the movement. Its indicator takes the form of a disc at 6 o’clock. The disc shows 24 hours and includes a day/night indicator. The triangle transferred to the subsidiary seconds dial represents the index by which the indication can be read. The disc is advanced by pressing the crown, each press moving the disc forward one hour at a time.

Finishing of the watch is of the very highest standard. The surfaces of pinions and wheels are totally flat and perfectly polished to exceptionally uniform tolerances. All finishing work on the main plate and bridges is carried out by hand to attain the best possible surface finish. Screws and all steel surfaces are finished and polished by hand.
