Object description

Case and Dial Design

The Patek Philippe Ref. 5004R is constructed as a three-body case in 18K pink gold, designed with a solid, polished finish. The case features a concave bezel and fluted lugs, reflecting a specific architectural profile. The transparent screw-down case back allows visibility of the internal mechanics. The case band integrates four correctors necessary for adjusting the perpetual calendar functions. A co-axial pushbutton is located within the crown, specifically serving the split-seconds chronograph mechanism.

The matte silver dial displays applied pink gold Arabic numerals. The dial is printed with an outer 1/5th seconds track featuring 5-second Arabic markers. Subsidiary dials occupy the space for the 30-minute register and leap year at the 3 o'clock position, the days of the month at 6 o'clock, and the seconds combined with a 24-hour indication at 9 o'clock. Apertures for the days of the week, the months, and moon phases are positioned centrally. The time is indicated by pink gold feuille hands.
