This 'Unico' perpetual calendar movement displays its functions via hands, with days at 6 o'clock, months and leap years at 9 o'clock, and the date at 12 o'clock. A moon phase display sits in an 8.50 mm window at 3 o'clock, showing alternating moons beneath a fumé sapphire crystal, while the mechanical chronograph features a central seconds hand with hour and 30-minute counters at 6 and 9 o'clock respectively.
