CHRONOGRAPH, COMPLICATION & VISION
A TREASURE CHEST OF PURE SAPPHIRE
To those of us in awe of Nature’s riches, sapphire is an iconic precious gemstone. To the world of Science, it’s a mineral known as Corundum, the second hardest material on earth after diamond, and almost impossible to scratch.
Herein, lies the beauty of this once-in-a-lifetime creation by the master horologers at Bell & Ross.
The extreme transparency of sapphire allows the eye an unequaled opportunity to virtually travel inside the movement and see the ingenious interactions in all their glory. Cutting a watchcase from a solid block of sapphire is an extremely difficult process. It takes long hours of machining, then polishing, to produce one. The BR-X1 CHRONOGRAPH TOURBILLON SAPPHIRE case is cut from 9 blocks of sapphire: middle piece, back, top, crystal and the four bumpers and is assembled with screws.
The complexity of the case construction is a challenge to technical mastery and makes it an exceptional and striking timepiece.
