Movement and Mechanics

The watch is powered by the self-winding Caliber 324/205 movement, which is rhodium-plated and finished with fausses cotes decoration. The movement contains 34 jewels and utilizes a straight-line lever escapement. It is equipped with a free-sprung Gyromax balance that is adjusted to heat, cold, isochronism, and 5 positions. A self-compensating flat balance spring and a shock absorber are utilized within the caliber. Power is delivered through a 21K gold rotor. The movement carries the Seal of Geneva quality mark.

Case and Dial Construction

The Patek Philippe Ref. 5135R-001 features a tonneau-shaped, solid 18K pink gold case measuring 38 by 51 mm with a thickness of 11.5 mm. The three-body construction includes a polished finish, a stepped bezel, and concave, curved lugs. The case band incorporates correctors for the calendar functions, and the watch is completed by a transparent screwed-down case back with sapphire crystals. The dial is designed with a two-tone guilloche and brushed silver aesthetic. It displays applied pink gold Arabic numerals at the 9 and 3 o'clock positions, complemented by dart indexes. The calendar displays are organized in apertures: the day of the week at 10 o'clock, the date at 12 o'clock, and the month at 2 o'clock. A sub-dial at 6 o'clock displays both moon phases and a 24-hour indicator, with pink gold dauphine hands providing the time indication.
