The Breitling AVI 1953 Edition RB0920131B1X1 is a limited-edition timepiece that pays homage to the original Co-Pilot Ref. 765 AVI from 1953. It features a 41mm 18k red gold case, a black dial with Arabic numerals, and tone-on-tone chronograph counters. The watch is powered by the in-house Breitling Manufacture Caliber B09, a hand-wound movement with a 70-hour power reserve. Protected by a highly-domed Hesalite crystal, it offers water resistance up to 30 meters. The AVI 1953 Edition is presented on a brown calfskin leather strap with an 18k red gold tang-type buckle. Limited to 253 pieces, each watch is engraved with 'ONE OF 253'.
