Bell & Ross BR 03 92 White Ceramic Diamonds (BR0392WHCDSCA)

The BR-X1, a high-tech chronograph with sporty looks, which is as robust as it is sophisticated, marked the arrival of a new Bell & Ross line and the beginning of a whole new chapter in the saga of the brand. The BR-X1 line expands with a new Haute Horlogerie version, the BR-X1 Chronograph Tourbillon, that was unveiled on 17th September, 2015, during Bell & Ross's traditional event at the Hotel National des Invalides, Paris.

An armoured, ingenious, muscular and technical watch, the BR-X1 has always stood out thanks to the innovative design of its 45 mm multi-material case. The functional, non-indexed screws, the single-piece structure of the case and the rocker pushers for the chronograph functions were designed to contribute to the sturdiness and ergonomy of the watch. A «thumb rest» insert is integrated at nine o'clock for optimised handling when activating the chronograph functions.

Sophistication prevails in the 45 mm case of the new BR-X1 Chronograph Tourbillon : rocker monopusher, thumb rest insert, virile looks. Its architecture remains unchanged with the grade 5 titanium "container" providing lightweight, robustness and water resistance. Cover, bezel, attachments, thumb rest, bumpers, crown guards, crown and caseback are made in 18 carat rose gold or titanium. The top of the range model of the BR-X1 range required a luxury watch movement, so Bell & Ross has developed a manual wind Skeleton Tourbillon Mono-Pusher Chronograph. This Haute Horlogerie grand complication movement consists of 282 components and 35 rubies and beats at 21,600 vph.

The BR-X1 Chronograph Tourbillon is available in two versions: grade 5 titanium or rose gold, with or without diamond setting (46 baguette-cut diamonds (2.3 carat) set into the bezel).

A skeleton tourbillon mono-pusher chronograph, this new BR-X1, with column wheel movement, displays hours and minutes in the centre, as well as a 100 hour (4 days) power reserve indicator at 9 o'clock.
It also has a 30-minute counter at 10 o'clock and a 60 second counter at 2 o'clock for the chronograph functions. The function is engaged by the mono-pusher rocker - positioned at 2 o'clock - which controls the Start, Stop and Reset functions. The minute counter of the chronograph features a semi-instantaneous jumping hand.
The seconds counter of the chronograph is a 6 impulse per second sweeping hand. The skeletonising of the movement allows the mechanics of this timepiece to be observed when starting, stopping and resetting the chronograph.

The "flying" tourbillon cage of the BR-X1 Chronograph Tourbillon is mounted without a support bridge, giving the impression that it is floating. Like a discreet signature, the ampersand (the iconic "&" of the brand) on the tourbillon cage sets the beat for the seconds.

The finishes of the movement and the case of the BR- X1 Chronograph Tourbillon abide by the codes of Haute Horlogerie: satin and polished, chamfered edges, polishing and perlage. The bridge of the chronograph and the tourbillon cage are made of ruthenium. The skeletonised movement allows the balance wheel to be admired through the dial.
From the front, the sapphire crystal has an antireflective coating. Made from grey-tinted sapphire crystal and featuring applique metal indices with photo-luminescent inserts, the dial forms a clear window through which the skeletonised movement can be appreciated. The sapphire crystal on the caseback exposes the geometry of the plates, which can be admired endlessly. The faceted, Superluminova®-filled hands and applique indices offer perfect legibility.

The bi-material high-strength rubber bracelet with alligator insert features a satin grade 5 titanium-steel alloy or 18 carat rose gold buckle.
