Object description

Case and Dial Design

The Patek Philippe Ref. 5004P is housed in a three-body solid platinum case, measuring 34 mm in diameter. The design incorporates a polished finish, a concave bezel, and distinctively shaped fluted lugs. The case construction features a transparent case back, allowing visibility into the movement, and is complemented by four correctors on the case band for adjusting calendar functions. A coaxial push button is integrated into the crown to operate the split-seconds chronograph mechanism.

The dial is rendered in black and features applied white gold Arabic numerals. Its layout includes auxiliary dials for the 30-minute register and leap year at the 3 o'clock position, days of the month at 6 o'clock, and seconds combined with a 24-hour display at 9 o'clock. Apertures for the days of the week, months, and moon phases are positioned on the upper half of the dial, while the perimeter displays an outer 1/5th second scale. White gold Feuille hands indicate the time.

Technical specifications for the movement include a straight-line lever escapement and a Gyromax balance equipped with a shock-absorber and a self-compensating Breguet balance-spring.
