SIHH 2008 Preview: Girard-Perregaux Vintage 1945 Square Perpetual Calendar

Girard-Perregaux revisits the perpetual calendar, incorporating this sophisticated mechanism in the elegant case of a Vintage 1945 Square. Automatically indicating the date, day and month, this timepiece is also the first to be equipped with the all-new Microvar free sprung balance.

With the Vintage 1945 Square Perpetual Calendar, the Manufacture has created one of the finest jewels of a collection which has been constantly updated with refinement. Inspired by a rectangular wristwatch created in 1945, Girard-Perregaux has developed this Art Deco derived line, retaining the clean spaces and straight angles, but adopting a square case. The curve of the domed dial and the recessed applique counters play on the depth and spaces.

The attention paid to the details is revealed in all the parts, down to the rounded indices. This timepiece displays the date, day, month and moon phase, automatically taking into account the length of the months and leap years. Its 1461 day (i.e. 4-year) "mechanical memory" takes into consideration the variations in the Gregorian calendar.

This concentrated piece of watchmaking technology requires the combination of hundreds of components, forming a complex architecture. The movement crafted in-house by Girard-Perregaux is visible via the transparent case-back.

The Vintage 1945 Square Perpetual Calendar also incorporates an innovation derived from Girard-Perregaux's research in the field of chronometry: the Microvar free sprung balance. This exclusive development by the Manufacture combines a six-screw system and two regulating weights positioned on the rim of the balance, which are used to respectively set the balance of the rim and the rate of the watch. This construction enhances the excellence of the timepiece, fully expressing Girard-Perregaux's know-how.
