Parmigiani Fleurier Tonda Quator Retrograde Annual Calendar self-winding automatic watch, features a 40mm 18k white gold case surrounding an ivory dial on a brown alligator strap with an 18k white gold tang buckle. Functions include hours, minutes, seconds, retrograde, day, date, annual calendar and moon phase. The development of thiscomplication is based on the brands PF 331 automatic movement, with the incorporation of an additional Parmigiani module, creating the PF 339 Annual Calendar. Valued for its everyday practicality, the Annual Calendar automatically accounts for the variation in the number of days in each month. Only one manual correction needs be made each year, (for the month of February in non-leap years). In a leap year, the date will display the 29 February and will automatically move to the 1 March the following day. The automatic model of the Tonda Annual Calendar, features a hand which indicates the date from 1-31 on the retrograde sector on the outer dial. The day of the week is positioned at 9 o’clock and the month, shown as a number from 1 to 12, is at 3 o’clock. Appreciated for the clarity of its progression, the precision moon, developed in the Parmigiani workshops, completes the indications of this Calendar model.
