Presented four years ago as a collaboration with Christiaan Van der Klaauw, the Midnight Planétarium watch lends itself to a version for women, inside a 38mm Lady Arpels case, with a carpet of diamonds on the bezel and the caseband. It plays host to the Sun surrounded by its closest planets: Mercury, Venus and Earth together with its satellite, the Moon. Each of these heavenly bodies orbits the dial, made of seven aventurine discs, at actual speed. Joining them in their graceful progress is a shooting star in rhodium-plated gold which shows the time, more with poetry than precision. On the back of the watch, day, month and year are displayed in two apertures, in the charming company of a crescent-shaped oscillating weight, sprinkled with diamonds.
