Period
circa 1910
This Swiss hunting-cased, keyless pocket watch, numbered 13939, dates to approximately 1910. The timepiece is crafted in 14K yellow gold and features a complex array of complications, including a quarter-repeating mechanism activated by a slide on the band, a chronograph function with a button at 12 o'clock, a triple-date calendar indicating the day, date, and month, and a moon phase display.
The movement is a frosted gilt caliber featuring 22 jewels, a straight-line lever escapement, and a notched bimetallic compensation balance with an overcoil hairspring. The dial is white enamel with Roman numerals, an outer chronograph track calibrated to 300 units, and several subsidiary registers for the time and calendar functions. The watch is accompanied by an 18K gold fancy-link long chain. It is presented in a four-body bassine-style case, which includes a hinged cuvette engraved with technical details and a glazed cover to view the movement.

Design
- Case and Dial
- The watch is housed in a four-body, bassine et filets case constructed from 14K yellow gold. The exterior features an engine-turned finish complemented by a polished band and borders. A chronograph button is situated at the 12 o'clock position. The case includes a hinged gold cuvette that is engraved with the object's technical specifications. Additionally, a glazed, gold-rimmed cover allows for inspection of the movement without exposing it directly. The white enamel dial displays radial black Roman numerals and an outer minute track. An outermost track provides fifths of a second divisions, calibrated to 300 units for timing purposes. Subsidiary dials are utilized for constant seconds, days of the week, date, and months, alongside a dedicated aperture for moon phases. The time is indicated by gilt Louis XVI hands.

All hands are confirmed as original to the piece. The watch is accompanied by an 18K gold fancy-link long chain, which is sold alongside the main lot.
- Movement and Complications
- The watch is powered by a frosted gilt movement, identified as Caliber 22???. It operates on 22 jewels and employs a straight-line lever escapement. The regulation of the movement is managed by an index regulator, paired with a blued steel Breguet balance spring featuring an overcoil. The balance wheel is a notched bimetallic compensation type. The timepiece incorporates a quarter-repeating function, which is activated by a slide mounted on the case band. These chimes are produced on internal gongs. In addition to the repeaters and chronograph, the watch functions as a triple-date calendar, tracking the month, day of the week, and date, while displaying the cycle of the moon through its aperture.
