Mu:n Watch: Blue Orion

MU:N Orion Blue – French Moonphase

The MU:N Orion Blue is a contemporary watch combining elegance, finesse, and a lunar complication. Its 316L steel case of 38 mm features brushed and polished finishes, applied indices, and premium luminescence, for comfortable and refined wear on all occasions.

The blue, dual-level dial blends sobriety and chic: the upper part evokes the lunar surface, while applied indices featuring Super-LumiNova ensure clear legibility day and night.

Mounted on a leather strap, the MU:N Orion Blue sports a transparent case back that reveals the Swiss manual-winding mechanical caliber Sellita SW288, adjusted for a precision of ±7 s/day, 4 Hz frequency, and a power reserve of approximately 41 hours. The watch also offers a moonphase + date complication, as well as a comfortable water resistance of 10 ATM (100 m), making it suitable for daily use, even in active environments.
