Bell & Ross expands its BR 01 Cyber Skull collection with the new BR 01 Cyber Skull Sapphire Ice Blue, a 45mm clear sapphire watch with an automaton skull whose jaw moves when the watch’s crown is turned while winding the movement.
The high-tech composite sapphire case allows a completely clear view of the manual-wind caliber and its components, whether viewed from the front or back of the watch. The highlight ice blue skull, made of galvanized brass and blue PVD (on the dial side), serves as a backdrop and mainplate for the skeletonized caliber BR-CAL.209, with its 48-hour power reserve and 28,800 vph frequency.
Bruno Belamich, creative director and co-founder of Bell & Ross, explains that the newest skull hue “combines perfectly with the transparency of the sapphire of the case, like a faceted iceberg.” 
The watchmaker notes that the case’s sapphire material is almost as hard and scratch-resistant as diamond. To produce the case, technicians use a hydrogen flame to heat an alumina powder to a temperature exceeding 2,000°C., a delicate and painstaking process 
Bell & Ross equips the watch with a transparent soft silicone strap held to the wrist with a polished and satin-finished steel pin buckle. The new BR 01 Cyber Skull Sapphire Ice Blue is a limited edition of 25 pieces, each priced at $115,000.
For each, a colorful open-work dial and crown match its brightly colored integrated rubber strap, which is set with a solid double-press deployant closure.
The movement’s flying carousel, silicon balance wheel and escapement are suspended by a bridge that acts as the minute hand while the second bridge serves as the hour hand.
