Characteristics

Measuring only 5.2 mm in thickness and a diameter of 12½ lignes, this is one of Panerai's slimmest automatic calibers with a GMT function. It features central hour and minute hands, a small seconds dial at 9 o’clock, a date display at 3 o’clock and a second-time zone using a separate GMT hand, which shows international time. The date, in this instance, adjust with the home time and not the local time. The movement's three-day power reserve is powered by a bidirectional oscillating weight and stored in a single barrel. The balance wheel, oscillating at 28,800 vibrations per hour, is stabilized by a balance cock. Additionally, the caliber includes a stop-second function for precise time settings, depending on the model.
