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.

Movement and Escapement

The watch is equipped with the Blancpain Caliber F585, a rhodium-plated movement. The movement features fine decorative finishes, including oeil-de-perdrix (partridge eye) patterns on the surfaces. It contains 37 jewels and operates using a straight-line lever escapement. Technical specifications for the movement include a monometallic balance that has been adjusted to five positions. It is fitted with a shock absorber system and a self-compensating flat balance spring to aid in precision. The entire mechanism is fully signed, as are the case and dial.
