Object description

Dial Presentation and Visible Exterior

The watch features a light cream or off-white dial punctuated by applied metallic Breguet hour numerals. A three-register chronograph layout occupies the face, with auxiliary subsidiary dials located at the 3, 6, and 9 o'clock positions utilizing blued indicator hands. The central chronograph seconds hand is finished in blued steel, contrasted against metallic leaf-style hour and minute hands. The dial bears the inscription 'GIRARD-PERREGAUX Tourbillon' directly below the 12 o'clock marker and 'SWISS MADE' along the outer scale at 6 o'clock.

The circular case is stated as platinum, measuring 40mm in diameter. Visual observation shows a brushed flat bezel combined with polished lugs, twin round chronograph pushers flanking the winding crown, and a fluted crown at 3 o'clock. The watch is mounted on a tan or brown stitched crocodile leather strap with pronounced scale texture, reported to feature an 18K white gold Girard-Perregaux pin buckle.

Reported Movement and Architectural Construction

According to cataloguing details, the timepiece is powered by the manual-wind calibre 9981 containing 46 jewels, bearing 'Movement No No. 2'. Unlike open-dial tourbillon configurations, the front dial retains an uninterrupted solid finish.

The catalog essay states that the movement is visible through a sapphire caseback, where three bridges form the mainplate to support the tourbillon, barrel, and gear train. It further reports that circular graining adorns the bridges and that the tourbillon cage is engraved by hand.

Evidence for this section
  • “Calibre Manual, cal. 9981, 46 jewels”
  • “Movement No No. 2”
  • “Through the sapphire caseback, the decorated movement takes center stage. The three bridges form the mainplate, supporting the tourbillon, barrel, and gear train”
  • “Circular graining adorns the bridges while the tourbillon cage is engraved by hand”

Cataloguing Details and Accompanying Material

Direct visual observation from the provided photo is restricted to the dial and front of the case. The movement finishing, reverse bridge construction, movement number, display caseback, and packaged accessories are not visible in the primary image and rely entirely on the catalog descriptions.

  • Does accompanying paperwork verify an exact sale date beyond the reported 'Circa 2012' estimate?
  • What specific alloy composition and markings are present on the movement bridges visible via the caseback?
