Based on caliber GP1800, the anthracite gray ruthenium movement has been skeletonized, and then hand chamfered, polished, and satin-brushed. Automatic caliber GP01800-0006, consists of 173 total components, 25 jewels, and has a 54-hour power reserve. Visible at 12 o’clock is a Microvar variable inertia balance that oscillates at 4Hz (or 28,800 vibrations per hour) and is exclusive to Girard-Perregaux.
A sleek 38 mm x 9.27 mm 18k pink gold case, with a sapphire caseback, houses this impressive movement, which displays just hours, minutes, and seconds.
Leaf-shaped hour and minute hands correspond with the chapter ring, which consists of applied hour indexes and minute transfers, on the flange – because there is no actual dial.
The Girard-Perregaux 1966 Skeleton is paired with a hand-stitched black alligator strap with a pink gold pin buckle. Water-resistance is 30 meters. (Ref. 49549-52-001-BB60) The price is $55,400.
In my opinion, the case is a perfect size, and the watch looks great overall. However, the huge “GP” logo applied to the flange at 12, throws off the visual balance of an otherwise nicely executed dial. Hopefully, that changes between now and delivery of the watch in the Fall.
