The 1966 collection is enhanced with a moon phases indicator that is particularly beautiful. Linked to the barrel, this function is a wonderful example of Girard-Perregaux expertise. It is joined, for the first time, in the 1966 collection, by a patented large date display. This highly perfected mechanism consists of two superimposed disks built into the GP03300 automatic manufacture movement. 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.

The curved dial features an applied baton-type markers and curved, polished leaf-shaped hands. This special design is both contemporary and classic - a distinguishing feature of the 1966 collection. The small seconds hand is centred on the moon phases indicator. The sapphire case-back reveals the movement composed of 290 parts, including its oscillating weight decorated with Côtes de Genève.

The case, with a diameter of 41mm, incorporates a slightly domed crystal and a polished, diamond-effect bezel elegantly inclined as part of its refined design. For optimal comfort on the wrist, the horns are also curved, giving the case a pure flowing line. The Girard-Perregaux 1966 large date and moon phases is available in white or pink gold. Both are fitted with an alligator leather strap secured by a gold pin buckle.
