At the heart of this Chronomat B01 is Breitling's self-winding mechanical caliber, delivering a 70-hour power reserve and full chronograph functionality — including 1/4th second, 30-minute, and 12-hour totalizers alongside the date display. The 42mm round stainless steel case is shielded by a cambered sapphire crystal that is glareproofed on both sides, while a sapphire caseback offers a view of the movement within.
The blue dial is dressed with luminescent index hour markers and luminescent silver-tone hands for reliable legibility, and the unidirectional ratcheted rotating bezel adds a layer of practical utility. A screw-locked crown and 200-metre water resistance round out the case's capable construction.
A blue rubber strap with a stainless steel fold clasp completes the ensemble, lending the watch a sporty character suited to active wear. Reference AB0134101C1S1 is offered here with its original box and papers included.
