The Tonda Métropolitaine Sélène Galaxy is an elegant and refined creation. This feminine interpretation of a great mechanical watchmaking classic displays the moon in all its cosmic glory, in the centre of an aventurine dial representing a star-filled sky.
The Calibre PF318 is an automatic-winding mechanical movement. Its two series-coupled barrels ensure 50 hours of autonomous and exceptionally regular operation. Its pendulum beats at a frequency of 28,800 vibrations per hour. Comprised of 205 components, it combines the display of hours, minutes, seconds and the date with the lunar phases. Its moon-phase mechanism is driven by a gear set in motion by the hour wheel, which turns twice as slowly as the former does. Thus, once every 24 hours this gear drives the moon disk by means of a flexible blade integrated into the centre of its wheel.
