The Excalibur Blacklight is inspired by the art world and reveals the innovation capacity of Roger Dubuis. During the day, colored micro-beams are spread inside the calibre, placed like rays of light going through the mechanism. Under UV light, the micro-beams are luminescent, like neon tubes glowing in a two faces sculpture revealing its full potential only under specific circumstances. Bringing together both art and innovation is what Roger Dubuis calls Art Technologies and allows the Geneva manufacture to offer exclusive watches in limited editions. Besides, the Excalibur Blacklight reflects the gender fluid approach of the designs created by Roger Dubuis in the world of Haute Horlogerie.More than a customer service, our conciergerie is here to answer any question and assist you in becoming a Roger Dubuis insider.Case Pink Gold case Pink Gold bezel set with gems Pink Gold crown Sapphire crystal with anti-reflective coating Pink Gold open case back with sapphire crystal 750/1000 pink gold Size: 42mm Water Resistance: 10 bar (100 m) Dial Pink double surface flange with engraved minute track and transferred texts, polished and pink gold 750/1000 plated hour markers colored in the center Main material: Pink Gold 18K Strap Bi-material rubber base and calf inlay, interchangeable with Quick Release System - QRS Type: Calf Color: Pink Clasp Pink gold 750/1000, triple folding buckle interchangeable with Quick Release System - QRS Type: Pink Gold 18K MOVEMENT Energy: Automatic, self-winding Indications: Hour - Minute Power reserve: 72 Hours Decor Sand-blasted and trued-up main plate and bridges Technical Details Number of pieces: 178 Number of rubis: 32 Diameter: 16 3/4 Thickness: 5.95 mm Frequency: 28800 Frequency (vph)
