Roger Dubuis Excalibur Blacklight Spin-Stone MB Limited Edition
Roger Dubuis presents Excalibur Blacklight Spin-Stone TM MB, a boutique exclusive variant of its Excalibur Blacklight Monobalancier watch, in a limited edition of 28 pieces.
The is the first timepiece to be set with curved and luminescent colored synthetic gems SPINSTONE TM on the bezel and on the flange, displaying red to blue rainbow. Blacklight microbeams turn tri dimensional to fit the iconic star shape, and are enhanced by colored SLN to glow by night and under UV light.
The case is made of EON GOLDTM, a specific 750/1000 5N gold alloy that is more resistant to tarnishing when exposed to extreme conditions.
This Excalibur watch is powered by Cal. RD720SQ, a mechanical skeleton self-winding Monobalancier movement with an increased power reserve up to 72 hours thanks to a new geartrain toothing and escapement optimization through its geometry. This calibre also offers improved durability thanks to new lube, and increased precision thanks to 4Hz frequency.
The skeleton movements manufactured by Roger Dubuis comply with one of the most respected certifications of Haute Horlogerie, the Poinçon de Genève.
