The BLS Factory Breitling Chronomat B01 42 AB0134 steel bracelet replica honors the 1984 icon that marked the triumphant return of the mechanical chronograph. Featuring a 42mm stainless steel case and the unmistakable unidirectional ratcheted bezel with four rider tabs at the 15‑minute marks — a design developed in collaboration with the Italian Frecce Tricolori aerobatic team — this 1:1 super clone captures the Chronomat‘s rugged aviation heritage. The sunburst dial, available in black, blue, silver, green, or copper (cream copper), pairs crisply with black contrasting subdials and baton‑style hour markers coated with Super-LumiNova® for excellent low‑light legibility. The prominent red chronograph seconds hand, the 30‑minute and 12‑hour totalizers at 3 and 6 o‘clock, and the discreet date window at 6 o’clock deliver full chronograph functionality with dial symmetry. The signature Rouleaux steel bracelet — polished bevels, angular links, folding clasp — stays faithful to the original 1984 silhouette while offering all‑day comfort. Inside beats a carefully crafted replica of the Breitling Manufacture Caliber 01: a COSC‑certified column‑wheel chronograph with vertical clutch, delivering 47 jewels, 28,800 vph, and an impressive 70‑hour power reserve. The sapphire exhibition caseback reveals the decorated movement, while 200m water resistance and a screw‑down crown make the Chronomat B01 equally at home in the boardroom, on the beach, or behind the wheel of a classic car. Whether you are a collector of iconic chronographs or a first‑time buyer seeking a true all‑purpose sports watch, the BLS Factory Chronomat B01 42 delivers the perfect balance of heritage design and modern precision.
