Object description

Case and Dial

The timepiece is housed in a two-body, rectangular, curved case measuring 34 x 47 mm and 12 mm in thickness. The exterior features a combination of polished and brushed surfaces, constructed from 18K pink gold. It is water-resistant and includes a transparent case back secured with eight screws, allowing visibility of the movement. The lugs are straight and utilize screwed white gold bars for strap attachment.

The ivory-toned dial provides the interface for the perpetual calendar functions. It is punctuated by oversized brown Arabic numerals and features blued steel spade hands. Calendar indications are displayed via apertures for the days of the week, months, leap year cycle, and moon phases, with a subsidiary date dial located at the four o'clock position.
