Girard-PerregauxThis Girard-Perregaux Aéro-Compax wristwatch, manufactured in 1959, is a stainless steel aviator timepiece featuring a round-button chronograph with multiple registers, a tachometer scale, and a secondary crown at 9 o'clock for operating a memento dial.
The 38 mm diameter, three-body case is finished with polished surfaces and tapered lugs, and it utilizes a screw-down caseback for water resistance. The dial displays a brushed beige and silver finish with luminous Arabic numerals and blued steel "lozenge" hands. Internally, the watch is powered by the Caliber 287, a 17-jewel movement featuring a straight-line lever escapement, monometallic balance, and an index regulator.
The piece is accompanied by a later Girard-Perregaux box and a copy of the company's certificate of authenticity.

- Case and Dial Design
- The watch features a 38 mm three-body stainless steel case characterized by polished surfaces and tapered lugs. Designed with an emphasis on utility, it includes a screw-down caseback to ensure water resistance. A distinctive feature is the use of two crowns; the crown positioned at 9 o'clock is specifically designed to adjust the memento dial. The dial is finished in brushed beige and silver and incorporates luminous Arabic numerals, facilitating legibility in various lighting conditions. The display includes an outer minute and fifths-of-a-second track, subsidiary dials for running seconds, 12-hour and 30-minute registers, and the 12-hour memento register. An outer tachometer scale surrounds the periphery, and the time is indicated by luminous blued steel lozenge-shaped hands.
- Movement Specifications
- The timepiece is powered by the Caliber 287, a frosted gilt mechanical movement containing 17 jewels. Regulation of the watch is achieved via an index regulator acting upon a self-compensating Breguet balance spring.
- Condition and Authenticity
- The auction description provides a grading for the watch, identifying the overall condition as very good. While the case and dial display slight scratching, the internal components remain in favorable working order. The watch is signed by the maker on the dial, case, and movement. To support its provenance and authenticity, the watch is accompanied by a copy of a Girard-Perregaux certificate. The set is presented in a modern, later-manufactured Girard-Perregaux box.
