Made for this year’s Only Watch auction event, the BR 01 Skull Bronze Tourbillon from Bell & Ross has a unique design inspired by pirate folklore. The piece is housed in a 46 mm square case constructed from aged bronze, featuring a dial that displays a hand-engraved skull in solid gold. It’s powered by the caliber BR-281, a mechanical movement with a tourbillon regulator-style time indication, with a 5-day power reserve and accuracy indicator functions. A distressed brown alligator strap completes the look. Packaged in a wood chest, the Bell & Ross BR 01 Skull Bronze Tourbillon will be sold through the 2015 edition of the Only Watch charity auction.
