Bell & Ross BR-X1 Tourbillon Sapphire
Limited to just five pieces, the Bell & Ross BR-X1 Tourbillon Sapphire is an extremely rare and exclusive beast. The transparency isn’t an illusion; the 45mm case is made entirely of synthetic sapphire, one of the hardest materials in the world.
The calibre 285 movement is equally as special. Manufactured in-house, it has a flying tourbillon and a mono-pusher column wheel chronograph with four days of power reserve. The watch is mounted on a translucent rubber strap with metallic Kevlar weave.
