The Bell & Ross BR-X1 Tourbillon Chronographe Instrument de Marine was introduced in 2016 as a limited edition of 20 pieces, pairing the high-tech BR-X1 look with materials reminiscent of classic ship chronometers. The case is made up out of parts in Indian rose wood and rose gold, while the movement is the hand-wound caliber BR-CAL.283 tourbillon chronograph.
Hand-wound movement with 4-day power reserve, flying tourbillon, and column wheel-operated mono-pusher chronograph, developed by Manufacture Haute Complication SA / formerly BNB Concept.
