Introducing Louis Moinet Expands the Speed of Sound Collection

Louis Moinet’s modern identity is shaped by curiosity and a willingness to question how historical watchmaking should exist today. Rather than treating the past as something to be preserved intact, the brand approaches it as a living language, one that can be reshaped through craft, rare materials, and contemporary ideas without losing its original meaning.

The Speed of Sound collection is a clear reflection of that philosophy. It does not exist to celebrate speed in the conventional sense, nor to chase visual spectacle for its own sake. Instead, it explores how a chronograph can be transformed into an instrument of observation, bridging science, astronomy, and mechanical tradition. With its latest releases, Louis Moinet expands the Speed of Sound collection with three limited editions.

The watch is housed in a Grade 5 titanium case measuring 40.7 mm in diameter and 18.7 in thickness. A domed sapphire crystal acts as a lens over the dial, amplifying its depth and detail. Turning the watch over reveals a transparent caseback that offers a clear view of the movement and its extensive hand engraving. Water resistance is rated at 30 meters.

The dial is executed in either orange, green, or black, serving as a backdrop for the rich materials and indications layered across its surface. Skeletonised hour and minute hands are filled with luminescent material, ensuring legibility without overpowering the overall composition. At the centre of the dial lies the defining feature of the Speed of Sound, a moonphase indication that abandons traditional representations in favour of a three-dimensional approach. A large, slightly domed disc carries a hand-drawn luminous lunar motif, while a fragment of the Dhofar 457 lunar meteorite marks the full moon. Two pointers positioned at 3 and 9 o’clock indicate the current lunar phase, with their alignment signalling the moment of fullness. Elsewhere on the dial, both the chronograph counter and the small seconds display are crafted from Aletai iron meteorite.

Powering the watch is the historic Valjoux 88 chronograph movement, originally developed in the 1940s and now extensively reworked by Louis Moinet’s watchmakers. The movement is manually wound and operates at a frequency of 18,000 vph (2.5 Hz), delivering a power reserve of 40 hours.

The watch is paired with a rubber strap that integrates seamlessly with the case through openworked lugs. Each edition is limited to just 3 pieces, and pricing is available upon request.
