Used in conjunction with the chronograph, this system serves to measure an average speed whatever the time elapsed, the distance covered or the speed reached.
Its originality is now further accentuated in an all black- clad 500-piece limited series.
This original and powerful approach continues on the reverse side of the watch with a spectacular 360-sculpted oscillating weight evoking the shape of a wheel rim and visible through a transparent caseback.
Beneath this stylish exterior beats Manufacture Breitling Calibre B06, a high- performance selfwinding chronograph movement chronometer-certified by the COSC (Swiss Official Chronometer Testing Institute).
The ingenious 30-second chronograph system, inspired by a Breitling patent dating from 1926, is distinguished by its central hand performing a full sweep of the dial in half a minute and thus ensuring extremely accurate 1/8 of a second time readings.
The dial also displays another world-exclusive feature of Breitling for Bentley instruments: a variable tachymeter, based on a circular slide rule.
The sculptor, who at times can be found inside his huge and popular costumes inflated by 12-volt motor blowers, says, Kuehnle also turns his creativity and mechanical know-how from costumes to site-specific installations that activate the space around them.
