Flyback chronograph perpetual calendar, moon phase, Leman, black dial, self-winding

To offer watch enthusiasts a timepiece truly without equal, Blancpain’s master watchmakers have perfected a self-winding perpetual calendar. Its mechanical memory automatically displays the day, the month, the date and the moon phase, even on leap years thanks to a diminutive satellite wheel that takes exactly four years to effect a single complete rotation. Conceived in 1853, the perpetual calendar has proved the most reliable of companion pieces, decade after decade.
