Object description

Case and Dial Design

The watch is housed in a two-body, polished platinum case characterized by concave lugs. The transparent case back is secured with six screws, allowing visibility of the movement.

The ruthenium dial incorporates off-center, guilloché-finished silver segments. These include a primary dial for hours and minutes with painted radial Arabic numerals, as well as secondary silver guilloché subdials designated for constant seconds and the 60-minute register. The layout also includes an aperture for the double-disc oversized date. Blued steel hands, specified as "Journe"-style, are utilized for time and chronograph functions.

  • “C. Two-body, solid, polished, concave lugs, transparent case back with 6 screws, sapphire crystals.”
  • “D. Ruthenium, off-center "guilloché" silver with painted radial Arabic numerals for the hours and minutes, subsidiary "guilloché" silver dials for the seconds and the 60-minute register, aperture for the double disc date.”

Movement and Mechanics

The watch operates on the self-winding Caliber 1300 movement. The plates are ruthenium-plated and decorated with "fausses côtes". The mechanism comprises 22 jewels, a straight-line lever escapement, and a monometallic four-arm balance.

The balance is equipped with four timing weights and is adjusted to five positions. It utilizes a shock-absorber and a self-compensating, free-sprung flat balance-spring. Winding is achieved via an off-center, bi-directional 22K gold rotor. The movement is inscribed with the designations "Exclusive Power Reserve System" and "Precision Chronometer".
