Louis Moinet Speed Of Sound

At the heart of SPEED OF SOUND is the Valjoux 88, a historic calibre built in the 1940s. Louis Moinet's master watchmakers have used all their skills to modernise this icon of Swiss watchmaking and place it inside a timepiece with a unique contemporary style.

Key to this intelligent and inventive transformation is the moon indication that has been entirely redesigned to offer a display never seen before in watchmaking. Its large, slightly domed disc features a lunar motif drawn by hand using luminescent paint that vividly recalls the splendour of the orb of the night.

A fragment of the Dhofar 457, a rare lunar meteorite, was placed on the same disc to symbolise the full moon. This fragment owes its colour to its origin: a lunar crater. The two pointers positioned at 3 and 9 o'clock indicate the current state of the moon. When the fragment is perfectly aligned with one of these indicators, it indicates the full moon.

Connoisseurs will notice that the date markers have been removed, a deliberate choice to reinterpret this calibre in a resolutely modern spirit.
