Design
- Case and Dial
- The timepiece features a solid three-body 18K white gold case, finished with a combination of polished and brushed surfaces. It is designed with an inclined bezel and distinctive triangular lugs, providing the watch with a diameter of 37 mm and a thickness of 12 mm. The assembly includes an 18K white gold Patek Philippe buckle. The matte silver dial displays applied white gold baton-style hour indexes. It incorporates a graduation for the days of the month, surrounding the moon phase aperture, which is rendered in yellow gold. Additional apertures are positioned on the upper half of the dial to indicate the day of the week and the month, while the time is indicated by white gold dauphine hands.

- Power is provided by the caliber 27-460 Q, a self-winding perpetual calendar movement. It is rhodium-plated and features fausses côtes decoration. The caliber is constructed with 37 jewels and a straight-line lever escapement. An 18K yellow gold rotor facilitates the automatic winding. Precision in timekeeping is maintained by a Glucydur Gyromax balance, adjusted to heat, cold, isochronism, and 5 positions. The movement is equipped with a shock absorber and a self-compensating, free-sprung Breguet balance spring. The movement is marked with the Geneva Quality Hallmark.
