Pre-owned/unworn Breitling Chronomat B01 42 ref. AB0134101L2S1 is a contemporary take on one of Breitling’s most iconic sports watches. The modern Chronomat combines rugged capability with refined aesthetics, making it equally at home on land or in the air. The example you see here features a robust 42mm stainless steel case paired with Breitling’s updated rider-tab bezel, whose slimmer profile gives the watch a more streamlined appearance while preserving one of the collection’s signature design elements. The rich green dial is contrasted by black tri-compax chronograph sub-dials, creating a sporty, highly legible display with plenty of visual depth. Complementing the dial is Breitling’s distinctive green rubber rouleaux strap, which recreates the rounded-link look of the famous metal rouleaux bracelet. Inside beats Breitling’s celebrated in-house caliber B01 automatic chronograph movement, prized for its column-wheel construction, reliability, and outstanding performance.
