The Mission Moon was evolved from the original M250 Chronograph worn by NASA astronauts in outer space in 2000. The current MM250-2 shares the same style, fit and boldness as its predecessors while achieving even higher utility with the upgraded case, skeleton rotor, varied guilloche patterning, rhodium applications and more. The MM250-2 represents the second series of 250 individually numbered Mission Moon timepieces, with the MM250-1 retired back in 2018 and the MM250-2 introduced at the start of 2022. The series offers two dial color references - silver or back. Each timepiece is made-to-order with your selected tachymeter, hands, and strap. Each color variant has the same MM250 reference, with 100 silver, 100 black and 50 multi-tone dials made for the series.
