The perpetual calendar is one such marvel. A mechanism of breathtaking complexity, it understands the vagaries of the Gregorian calendar, automatically accounting for 30 and 31-day months, and even correctly displaying February 29th every leap year. It will not need a manual correction until the year 2100, a date most of its owners will never see. It is, in essence, a machine that holds a fragment of eternity within its gears.
Then there is the chronograph, a wearable stopwatch. To witness the crisp start, stop, and return-to-zero of its central seconds hand is to experience tactile perfection. The split-seconds chronograph, or "Rattrapante," takes this further, featuring two superimposed seconds hands to time intermediate laps—a feat of engineering that represents one of watchmaking's most daunting challenges.
