Case and Dial Design
The watch features an 18K pink gold three-body case, which measures 37 mm in diameter. It is constructed with a combination of polished and brushed surfaces, complemented by concave lugs and a stepped bezel design. The case includes sapphire crystals and a transparent screwed-down case back, allowing visibility of the internal movement.
The dial is executed in guilloché pink gold, featuring applied white gold Arabic numerals and triangular indexes for hour markers. Blued steel "Feuille" hands indicate the time. The dial layout includes an auxiliary dial for the date, with apertures for day-of-the-week, month, leap year, and moon phase indications, as well as an inscription referencing the observatory.
