www.worldwatchweb.com - On the back of each RJ 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. Here are a few glimpses of how RJ truly brings the moon to your wrist.

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°C: the operation was successfully conducted at Cendres + Métaux, a company based in Biel, Switzerland and specialising in the treatment of metals for high-end watchmaking.

Blanking

The MOON SILVERRJ 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 RJ 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. Nonetheless, it must be carefully hand-worked to create the lunar disc of the Moon Invader watch.

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 devotes his talent to achieving the perfect finish for the RJ MOON SILVERRJ disc.

Wearing

Once completed, the silver-moon dust alloy disc is placed on the back of the watch, thereby lending unique character to each individual “moonscape” as it experiences a unique and direct contact with the owner’s skin..
