The Meteorite Tourbillon Perpetual Calendar Manufacture timepiece embodies the founders' visionary quest to render Swiss watchmaking savoir-faire and innovation more accessible. This unique Only Watch piece is presented in a 42 mm diameter 3-part 18K rose gold case with a see-through case back to let one admire the delicate Perlage & Côtes de Genève decorations.

The watch features a stunning, skeletonized blue tint meteorite dial. This four billion-year-old, very rare material fell on Earth 80'000 years ago and was found in Namibia, Africa back in 1839. The Perpetual Calendar complication also displays the day, date and month and requires even less adjustments than an annual calendar.

This highly sophisticated complication acknowledges the number of days each month, displays the year and automatically adjust itself on the leap years. Once set, it will remember the months with 30 and 31 days, the 28 days of February as well as the leap year cycle with the return of 29th of February every four years.

The Perpetual Calendar doesn't require any manual correction before 400 years, although there is an exception in the Gregorian Calendar, the watch will need to be adjusted on March 1st, 2100. The hour and minute functions are all adjustable through the crown. The dial presents at 12 o'clock the months and leap year, at 3 o'clock the days and at 9 o'clock the week days. The tourbillon's cage sits at 6 o'clock, with its incorporated seconds hand that rotates once every minute.
