Case and Dial Design
The watch features a three-piece, massive 18K gold case constructed in a bassine form, characterized by its polished surfaces. A notable feature of the case design is the glazed back, which allows for the viewing of the dual-face configuration. The primary dial is executed in white enamel, marked with Roman numerals. It incorporates multiple subsidiary indicators, including the days of the week, calendar dates, and months, alongside an inner subsidiary seconds display. An aperture for the moon phase is also present, featuring an age scale along its border.
The reverse side of the watch reveals a secondary white enamel dial dedicated to world time functionality. This display is organized with seven small subsidiary dials, each indicating the time in specific international cities: Paris, London, St. Petersburg, Calcutta, Melbourne, Vienna, and Berlin. The timekeeping functions on both faces are executed using blued-steel spade hands, maintaining a consistent aesthetic across the double-face arrangement.
