Pairing red gold accents with a stainless steel frame, this Breitling Avenger two-tone replica delivers a mixed-metal look that few pilot watches attempt. The UB01821A reference from Breitling sits firmly in the large-format Avenger range, measuring 45mm across with a unidirectional ratcheted bezel and thick sapphire crystal. Rather than committing to a full gold case, the design limits the red gold tone to the bezel, the crown, the pusher caps and the bracelet’s centre links, producing a warm contrast against brushed steel flanks that reads as both dressy and robust. On the two-tone bracelet shown here the reference is UB01821A1B1U1, the bracelet version of the UB0182, a genuine edition limited to 250 pieces; UB01821A1B1X1 is the same watch on a strap.

The rider tabs on the bezel remain a signature Avenger detail. They allow rotation with gloves or wet hands, a practical feature carried over from the original military-aviation roots of the collection. On a gold bezel they serve the same function but add a visual flourish that bare steel rider tabs never achieve.

Two-Tone Bracelet: Red Gold Tone Between Steel

Inside sits clone Cal. B01, an automatic chronograph movement driving three subdials plus a date aperture at six. The two-tone construction extends to the bracelet, where polished gold center links alternate with brushed steel outer links. That alternation catches light in stripes as the wrist moves, which is the defining visual characteristic of any two-tone bracelet design.

If you prefer a monochrome alternative in the same dimensions, the AB01821A blue dial version uses the same case geometry in full steel with a blue face.

Where a Two-Tone Avenger Replica Fits

Two-tone pilot chronographs occupy a narrow space between dressy and rugged. The gold bezel pulls the watch toward evening wear, while the 45mm steel case and thick lugs keep it grounded in the tool-watch category. On the wrist, the mixed metals catch light differently from every angle, creating an effect that full-steel or full-gold cases cannot reproduce. Breitling positions few Avengers in two-tone, making this a relatively uncommon configuration within the range. This two-tone Avenger super clone fills a specific gap for anyone who wants the oversized Avenger silhouette dressed up a notch beyond full steel.
