The Avenger A3239011/G778/436X/A20D.1, seen from the bench

The Breitling Avenger A3239011/G778/436X/A20D.1 is a dual-time tool watch introduced in 2001 for military aviators and special forces. The 43 mm stainless steel case houses the Caliber 32 automatic movement, featuring independent 24-hour hand adjustment for simultaneous dual time zone reading. The oversized screw-down crown, unidirectional bezel, and 300-meter water resistance reflect purely functional design, while the 22 mm lug width accommodates robust, square-profile lugs integral to this first-generation Avenger design.

Frequently asked questions

What is the lug width of the Breitling Avenger A3239011/G778/436X/A20D.1?

The lug width of the Breitling Avenger A3239011/G778/436X/A20D.1 is 22 mm. This measurement refers to the internal distance between the two lugs and determines the correct strap width for any replacement purchase.

What is the best strap for the Breitling Avenger A3239011/G778/436X/A20D.1?

For this model, vegetable-tanned Tuscan calf leather is recommended for daily wear, smooth alligator for formal occasions, vulcanised rubber for sport use, and NATO for maximum aeronautical authenticity. All replacements must feature a 22 mm lug width.

How do you change the strap on a Breitling Avenger A3239011/G778/436X/A20D.1?

Strap removal requires a springbar tool. Insert the forked tip into the lug slot to compress the spring bar, releasing the strap. The operation takes approximately two minutes and requires no specialist tools. It is advisable to work on a soft surface to protect the case from scratching.

Are there aftermarket straps compatible with the Breitling Avenger A3239011/G778/436X/A20D.1?

Yes. Any strap with a 22 mm lug width and standard spring bars is compatible with this model. Milano Straps offers a curated selection of Italian-made artisan straps in various leathers and materials, fitting the original Avenger lugs without adapters.

How long does a leather strap last on a Breitling Avenger A3239011/G778/436X/A20D.1?

Longevity depends on material and usage. A vegetable-tanned calf strap, with regular care, typically lasts 2–4 years. Alligator, being more resistant to deformation, can exceed 5 years. Prolonged immersion, excessive perspiration and direct heat should be avoided. A uniform patina is expected and enhances the strap's character over time.
