About the Avenger family
The Avenger was introduced in 2001 as a rugged, military-inspired line within Breitling's aviation range, with large cases, a rotating bezel with rider tabs and bold numerals.
It was relaunched in 2019, when it also took over elements of the discontinued Colt, and refined again in 2023 with fewer sizes and models. The catalog includes automatics, GMTs and chronographs, with calibers listed as 13, 17, 24 and 32 and the B01 on newer models, in steel, Breitlight and DLC-coated finishes. Dealers identify the generation, size and caliber from the reference and check the bracelet or strap.
