Girard-Perregaux introduces a new 1966 timepiece with a patented large date display function. The 1966 Large Date and Moon Phases has a mechanism consisting of two superimposed disks built into the GP03300 manufacture movement. According to the manufacturer, “It displays the date with no border between the digits for exceptional readability. The upper disk is virtually invisible thanks to its transparency and its thickness of 0.10 mm, equivalent to a sheet of paper.” Notably, the date advances in less than 100th of a second.

The 1966 Large Date and Moon Phases case measures 41 mm by 11.22 mm and is available in either a white or pink gold. All surfaces are polished to a mirror finish. The crystal is slightly domed, as are the bezel and the dial. The opaline dial features baton-type markers and leaf-shaped hour and minute hands. A small second display sits at 6 o’clock, with the moon phases displayed in the center of the same subdial.

Housed inside is the caliber GP03300-0110 automatic movement which runs at 4Hz and a 46-hour power reserve. The sapphire caseback reveals the movements 290 parts, including its oscillating weight decorated with Côtes de Genève.

Water-resistance is 30 meters. Comes on black alligator leather with matching pin buckle. (Ref. 49546-52-131-BB60 – pink gold, 49546-53-132-BB60 – white gold)
