Mu:n watch: Cobalt Origin

MU:N Origine Cobalt Edition - French Moon Phase

The Mu:n Origine Cobalt is the iconic automatic version of the Artemis collection. Conceived as a designer watch with a true horological dimension, the Mu:n Origine Cobalt features a 38mm polished 316L steel case, an anti-reflective sapphire crystal, and a very deep midnight blue dial, enhanced by a steel second hand. At the heart of the Mu:n Origine Cobalt beats the Swiss automatic Sellita SW288-1A caliber, adjusted to ±7 s/day and equipped with a poetic moon phase complication.

The moon phase is displayed at 12 o'clock, accompanied by a date display and a moon age scale, while a peripheral 24-hour graduation reflects the solar cycle. With its French calfskin strap with Alsavel lining, the Mu:n Origine Cobalt embodies the collaborative and transparent DNA of the brand, between French design and Swiss Made execution.
