Object description

Case and Dial

The watch features a 37mm case constructed of white gold. The design is characterized by an extensive use of diamonds, with 472 stones totaling approximately 3.23 carats set into the bezel and the lugs of the case.

The dial is rendered in luminous mother-of-pearl, which creates varying tones when exposed to light. Legibility is maintained through the use of applied Arabic numerals and hands. The arrangement includes dual subdials for the day and month, a moon-phase aperture positioned above the six o'clock index, and a date window located at the six o'clock position.
