Automatic movement

With its refined aesthetics, the Tonda Métropolitaine cannot fail to impress with its elegance and sobriety. This creation, with its superbly crafted automatic movement, features a modern urban style that embodies today’s active woman to perfection.

The Calibre PF310 is an automatic-winding mechanical movement whose dimensions (23.9 mm diameter) are perfectly suited to a woman’s watch. The sheer excellence of its design is magnified by superb finishes, with bridges angled by hand and “Côtes de Genève” decoration. Its two series-coupled barrels ensure 50 hours of autonomous operation. Its pendulum beats at a frequency of 28,800 vibrations per hour.

Comprised of 189 components, it allows for the display of hours, minutes, a small second and the date.
