Mu:n Watch: Grey Orion

MU:N Orion Grey – French Moon Phase

The MU:N Orion Grey is a contemporary watch combining elegance, finesse, and a moon phase complication. Its 316L steel case, measuring 38 mm, features brushed and polished finishes, applied indices, and premium luminescence, for a comfortable and refined wear on any occasion.

The dark grey, two-level dial blends sobriety with chic: the upper section evokes the lunar surface, while applied indices featuring Super-LumiNova ensure clear legibility day and night.

Mounted on a leather strap, the grey Mu:n Orion features a transparent case back that reveals the hand-wound Swiss mechanical caliber Sellita SW288, adjusted for a precision of ±7 s/day, at a frequency of 4 Hz, with a power reserve of approximately 41 hours. The watch also offers a moon phase + date complication, as well as a comfortable water resistance of 10 ATM (100 m), making it suitable for daily use, even in active settings.
