On the back of each Moon Invader watch, a silver disc evokes a miniature moon featuring a moonscape-textured surface. A few grams of moon dust have been injected into the silver, accordingly named Moon Silver, from which this disc was cut out. FUSION The moon dust (a certified sample) is amalgamated with the precious metal in a crucible. This amalgam requires perfect mastery of silver fusion, at a temperature of exactly 961�� celsius the operation was successfully conducted at Cendres & M��taux, a company based in Biel, Switzerland and specialising in the treatment of metals for high-end watchmaking. BLANKING The Mon Silver is then poured into ingots that are laminated to the thickness required to be blanked into rough discs ready to be stamped. The Moon Silver used by Romain Jerome is in itself an extremely special "technological" silver that acquires a beautiful patina through contact with the wrist rather than merely becoming oxidised like ordinary silver. FINISHING The rough silver discs are then repeatedly struck with a dedicated tool in successive stamping operations interspersed with annealing operations on the matter, before being entrusted to the master-engraver who creates perfect finish for the Romain Jerome Moon Silver disc.
