At the heart of this Chronomat B01 is a self-winding mechanical movement driving a full chronograph complication alongside hour, minute, second, and date functions. The copper-toned dial is fitted with luminescent silver-tone hands and luminescent index hour markers, while a cambered sapphire crystal — glareproofed on both sides — keeps everything clearly legible. A date display sits at the 6 o'clock position for everyday convenience.
The round 42mm stainless steel case features a unidirectional ratcheted rotating bezel and offers water resistance to 200 meters, making it a capable companion in demanding conditions. A black rubber strap secured by a stainless steel folding clasp rounds out the package with a purposeful, sporty feel.
This example comes complete with its original box and papers, reference AB0134101K1S1, representing the Chronomat B01 in one of its more distinctive dial configurations.
