The Bell & Ross BR-X1 Instrument de Marine was introduced in 2016 as a limited edition of 2016 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, bronze (CuSn8) and titanium, while the grey-tinted sapphire crystal dial offers a view of the BR-CAL.313 movement.
