Bell & Ross BR-X1 Chronograph Tourbillon Sapphire Limited Edition
This high-tech, haute horology creation from Bell & Ross’ BR-X1 line combines two prestigious horology complications – Mono-pusher chronograph and Tourbillon – inside a painstakingly crafted Sapphire exterior which offers unlimited opportunities to admire the beauty of mechanical movement.
The BR-X1 CHRONOGRAPH TOURBILLON SAPPHIRE is built around a Flying Tourbillon master grand complication and Bell & Ross has added an ultra elegant mono-pusher chronograph. This unique and exclusive Haute Horlogerie caliber is prepared to be roused by the exquisite poetry of its movement.
The chronograph complication is visible and provides a privileged window into its many intricacies. Even the casual observer can admire the column wheel under the dial at 12 o’clock, the semi instantaneous jumping hand (rather than a traditional sweeping hand), and the power reserve indicator of 100 hours (at least 4 days) at 9 o’clock.
Masculine through and through, the main plate and pillars have been machined from a single block of metal. The perfectly executed skeletonizing of the movement, in a stunningly contemporary style and finish, allows the exceptional mechanics of this “horological turbine” to be observed when starting, stopping and resetting.
True aficionados will appreciate the extreme sophistication of the BR-X1 CHRONOGRAPH TOURBILLON SAPPHIRE with its 30-minute counter at 10 o’clock and 60-second counter at 2 o’clock for the chronograph functions. These are engaged by the mono-pusher rocker –positioned at 2 o’clock– which controls the Start, Stop and Reset functions.
A treat for the eyes, this outstanding timepiece offers breathtaking views into its inner workings. The power reserve differential and the barrel are also visible on the back. In a similar theatrical fashion, the flying tourbillon cage with the logogram “&” can be seen from every angle.
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 Bell and Ross 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.
