Truly unique watch creations are presented by Experimental BR-X2 collection by Bell & Ross brand. BR-X2 Tourbillon watches in this series are all about fusing the case and the movement into one single, fluid action allowing the case to completely disappear from view. The idea with this collection was to keep the square case design but remove as much extra material as possible to allow for virtual invisibility. The Bell and Ross collection is limited to two options, the BR-X2 Skeleton Tourbillon Micro Rotor Watch and the BR-X2 Tourbillon Micro Rotor Watch, both of which come with retention screws and anti-reflective sapphire, and are 42.5 millimeters in diameter. Both have stainless steel cases, have a gray alligator leather strap, and have a folding steel clasp. Each model can by submerged in water up to 165 feet and do not come with a bezel. Functional movement is automatic and each watch displays hours, minutes, and flying tourbillon.
