– Year displayed in 4-digits between 7 o’clock and 8 o’clock.


Its functions are hours, minutes, seconds, perpetual calendar functions (day of the week, date, month, year), red security zone (turns red during a certain time of day when the time and perpetual calendar function should not be adjusted to prevent damaging the delicate mechanism) and moon phase display. Corrector for calendar functions is located on the side of the case at 8 o’clock.
