Object description

Case and Dial

The watch is housed in an 18K pink gold case, characterized by a three-body construction with both polished and brushed surfaces. It features a stepped bezel and includes correctors on the case band for adjustment of the calendar functions. For water-resistance, the timepiece utilizes a screw-down winding-crown, screw-down buttons, and a screw-down transparent case back, all secured with sapphire crystals.

The black dial is fitted with luminous Arabic numerals and an outer 1/5th seconds track. It displays the time via luminous pink gold sword hands. The dial configuration includes subsidiary registers for the 12-hour and 30-minute chronograph functions, alongside calendar displays for days of the week, months, and leap years. An aperture at the 6 o'clock position shows the moon phases, accompanied by a graduation for the age of the moon.
