Housed in a round 42 mm stainless steel case, the Chronomat B01 42 reference PB0134101C1S1 centers on an ice blue dial dressed with silver-tone luminescent hands and luminescent index hour markers, minute markers tracing the outer rim, and a date window positioned at 6 o'clock. A uni-directional rotating stainless steel bezel frames the dial, while a scratch-resistant sapphire crystal and screw-down crown protect the interior. The transparent case back offers a view of the movement within, and the watch carries a water resistance rating of 200 meters.
Power comes from the Breitling Calibre 01 automatic movement, an in-column-wheel chronograph engine built from 346 parts set with 47 jewels, oscillating at 28,800 vph and delivering approximately 70 hours of power reserve. Three sub-dials track 60 seconds, 30 minutes, and 12 hours of elapsed time, rounding out a full suite of chronograph, date, hour, minute, and second functions. The movement carries chronometer certification, reflecting Breitling's precision standards.
The watch is worn on a black rubber strap secured by a fold-over clasp, lending a sporting character that complements the Chronomat's aviation-inspired heritage. Both the original box and original papers are included with this reference.
