- Case and Exterior
- The watch is enclosed in an 18K gold hunting case, measuring approximately 55mm in diameter. The case is of the 'a-goutte' hunting style. The weight of the watch is approximately 177 grams. A glazed aperture at the back allows for the observation of the movement while the watch is closed. The crown is located at the 3 o'clock position in relation to the dial, with a repeater slide on the case band.
- Dial and Complications
- The timepiece features an original enamel dial with a standard analog display supplemented by a complex set of astronomical and calendar functions. A moon phase display is located at the 12 o'clock position, and the calendar mechanism includes a retrograde date display. The watch also includes a minute-repeating complication. The auction description states that, based on their research, this specific configuration—incorporating the retrograde date with the perpetual calendar and repeating mechanism—is the only known example of its kind.
- Movement and Signatures
