This self-winding caliber features a second timezone, day/night display, power reserve indicator, and date. It indicates reference time at 12 o’clock, half-hour timezone in the center, reference day/night at 9 o’clock, a date linked to the second timezone at 6 o’clock, and a timezone/date indicator at 4 o’clock. The second timezone allows for 30-minute adjustments via a crown-mounted pusher, and the mechanism includes a secured date correction system.
