This self-winding movement features an annual calendar and a second time zone, requiring only one date correction annually when moving from February to March. For other months, the mechanism automatically advances from the 30th or 31st to the first of the next month. A subdial at 8 o’clock displays a 24-hour reference time, while the GMT function is managed by the central hour hand linked to the date, with large apertures designed for clear legibility.
