Breitling’s all-purpose watch for your every pursuit. The Chronomat holds a significant place in Breitling’s history. Introduced in 1984, at a time where extra-thin quartz timepieces were the order of the day, Breitling placed a bold bet on an impressively proportioned mechanical watch. Based on the Frecce Tricolori chronograph, which had been developed and launched in 1983 in collaboration with the famed Italian aerial squadron, the Chronomat celebrated Breitling’s centenary in style and marked the return of the mechanical chronograph to its rightfully prominent place at the brand which had built its global reputation on these incredible watches. Available in a variety of materials including stainless steel and 18k red gold, the Chronomat features a 42 mm case and the iconic bezel with the four rider tabs. Available with a range of black, blue, silver, and copper dials, the Chronomat is matched to the signature “Rouleaux” bracelet and is powered by the in-house Breitling Manufacture Caliber 01, a COSC-certified chronometer.

Breitling Chronomat B01 42mm Black Dial Silver Steel Strap Watch For Men
The Chronomat B01 42mm is Breitling’s definitive all‑purpose chronograph—engineered for versatility, built to endure, and styled to stand out. Rooted in a storied lineage that revived the mechanical chronograph in the 1980s, this model blends a bold, aviation‑inspired heritage with contemporary precision and craftsmanship.
At the heart of the Chronomat B01 is Breitling’s in‑house Caliber 01 automatic chronograph, a robust engine with a stable 4Hz rhythm and a 70‑hour power reserve. The movement drives a clean, three‑dial chronograph layout on a striking black dial with silver sub‑dials, all visible through a sapphire crystal back that invites a closer look at the finely finished mechanism. The 42mm stainless steel case pairs with a polished, modern Rouleaux bracelet—a design that’s been reimagined for greater durability and everyday refinement. The unidirectional bezel retains the Chronomat’s signature rider tabs, offering a tactile, precise feel when timing events or simply accenting the watch’s sculpted profile.
