Movement is the new Swiss automatic Girard-Perregaux in-house caliber GP01800-0005 with 31 jewels, 28,800 vph and a power reserve of 54 hours. The Manufacture’s artisans have decorated the movement with traditional techniques: Côtes de Genève on the main-plate and gear train bridges and sunburst decoration on the rotor. An eagle, a symbol of Girard-Perregaux since 1897 and a reference to the special Anniversary Edition are also engraved on the movement.
The face of the series models takes up the Manufacture’s emblematic Golden Bridge. Situated at 6 o’clock, it stretches above the oscillations of the Microvar balance for the first time. On this edition, Girard-Perregaux alternates the colors, finishes, decorations of the dial and types of indexes. Depending on the period, the index also adopt different styles. At 9 o’clock, the small golden plaque, mounted directly on the movement, appears on the face through a window. At the center, a quote emphasizes a relevant event of the year displayed: be it in Girard-Perregaux’s history or in horology’s, but also cultural, scientific or politically significant milestones.
It comes on a black hand-stitched alligator leather strap with an 18kt rose gold folding buckle.
