Inspired by ancient legends, the BR 01 Skull Bronze Tourbillon is the one-of-a-kind timepiece made by Bell & Ross for Only Watch 2015. The "aged" look is due to the use of a CuSn8 bronze case, an alloy with a high phosphorous content that makes the watch robust and resistant to wear. The dial is decidedly original, featuring a hand-engraved 18-carat solid gold skull at 12 o'clock; at 6 o'clock, on the other hand, is the tourbillon cage, a complication that combines the functions of regulator, precision indicator and 5-day power reserve. The movement that regulates them is the hand-wound BR-Cal.281 calibre, which can be admired through the sapphire glass porthole in the titanium back. The water-resistance rating is 3 atmospheres; the strap is brown alligator, fastened by a steel pin buckle with a PVD titanium finish.
