Breitling positions the Avenger B01 Chronograph as its most rugged chronograph platform, and this Breitling Avenger B01 Chronograph 45 replica translates the AB01821A1B1X1 reference into a 45mm stainless steel case with an anthracite dial and a black strap with white stitching. The oversized crown guards and projecting rider tabs on the rotating bezel give the watch a distinctly military profile that separates the Avenger from every other collection in the catalog. At 45mm across, this sits at the upper boundary of what most buyers consider a mainstream wrist size, lending it unmistakable presence. The genuine is limited to 500 pieces, and our guide to the movements inside Avenger replicas covers the B01 and the other calibres.

Column Wheel, Vertical Clutch, Clone Cal. B01

The B01 caliber designation signals Breitling’s in-house automatic chronograph movement with a column-wheel switching mechanism and vertical clutch coupling, and the clone Cal. B01 in this watch copies that layout. That architecture delivers a clean chronograph start without the stuttering hand motion common in less advanced cam-lever designs. The genuine B01 is rated at 70 hours of power reserve; this clone stores about 55 hours when fully wound. Compared to the V17311101B Blackbird 44, a time-only automatic, this chronograph reference offers a fundamentally different ownership experience rooted in traditional horology. Browse the full Avenger lineup to see how the collection spans both time-only and chronograph movements.

Avenger B01 Chronograph 45 Replica: Anthracite on a Black Strap

Side by side with Chronomat references of similar diameter, the Avenger trades polished accents for a utilitarian matte finish across its case flanks, lugs and bezel. The crown guard architecture is noticeably thicker, the numerals are bolder, and the overall design language clearly favors function over refinement. This anthracite Avenger clone on strap represents the tool-watch end of the spectrum, built for legibility and sustained durability rather than versatile dressing.
