- The watch is housed in an 18K gold three-body case. The exterior features an engine-turned back, complemented by a reeded band and bezel. The case architecture is engineered to support its complex functions, with correctors for the month, date, and moon age integrated into the band. The band also accommodates a bolt for the activation of the quarter-repeating mechanism. Furthermore, a slide is incorporated into the case back, allowing for the opening and closing of the winding aperture to protect the movement.

At the six o'clock position, the watch features an aperture showing the age of the moon. An index regulator is positioned at the twelve o'clock mark, allowing for adjustment of the timing. The time is indicated by gold Breguet hands, and the dial is signed.
- Movement and Condition
- The 30 mm movement is frosted and gilt. It is equipped with a cylinder escapement and a three-arm balance featuring screws and a flat balance spring. The regulator is tied to an index located on the dial, and the quarter-repeating mechanism functions via gongs activated by the bolt in the case band. According to the auction description, the movement is in 'Good' condition but currently requires an overhaul. The dial shows signs of patination, and the case is noted as being in 'Very good' condition.
