The new Girard-Perregaux watch is available in an 18kt rose gold case. Its measurements are 40mm x 10.5mm. Both front and back sides of the case are fitted with sapphire crystals. The model is submersible to 30 meters.
Ticking inside the model is a Swiss made automatic Girard-Perregaux GP033M0 caliber movement, built on 44 jewels. It operates at a frequency of 28,800 vibrations per hour. The mechanism incorporates a barrel, snailed on its cover and sunray-brushed on the underside. It ensures a 46-hour power reserve.
The mechanism is also fitted with a manufactory-made Microvar variable inertia balance wheel. It is fitted with six adjustable screws and two inertia-blocks on its rim, utilized correspondingly to set the balance wheel's equilibrium and ensure perfect adjustment of the caliber.
Integrated within the movement is also a rhodium-plated main plate, which demonstrates diamond-cut facets and is circular grained above and below. The caliber animates an array of practical functions, presented on a dark-toned dial.
The display indicates central hours and minutes. The small seconds tick away in a counter at 9 o’clock. The face of the new Girard-Perregaux 1966 Annual Calendar and Equation of Time watch also provides an annual calendar function, which includes date and month indications.
Taken into account automatically, the length of the month needs to be corrected only occasionally, that is every 28th February of non-leap years. The corrections are made with a winding crown, in both directions.
The hallmark feature of the dial is an equation of time device, arranged at 4.30. It indicates the difference between the real solar time and the mean or civil time.
The new Girard-Perregaux watch is teamed with a black leather strap.
