The BR-X2 Skeleton Tourbillon Micro-Rotor is an addition to the futuristic ‘Experimental’ collection from Bell & Ross. Pared back to the bare essentials, this ultra-modern watch gives the impression that the movement is being worn directly on the wrist. Its 42mm polished steel case is set between two sapphire crystal plates, while polished, bevelled sides and clear gaskets ensure the case is almost invisible. Available in a limited edition of just 50 pieces.
