Strap for Avenger II GMT Stainless Steel / Stratus Silver / Military / Pin

The lug width of the Breitling Avenger A3239011/G778/106W/A20BA.1 is 22 mm. This measurement should be taken at the narrowest point between the inner faces of the lugs using a calliper or a precise millimetre ruler, to ensure an accurate fit for any replacement strap.

For this 43 mm Avenger, the most appropriate options are: alligator leather in a matte finish for a formal register, shell cordovan for those seeking a natural patina over time, vulcanised rubber for sporting use, and 22 mm ballistic nylon NATO for a tactical-military context. A stainless steel 316L deployant clasp is the closure most consistent with the model's construction philosophy.

To replace the strap, use a fine-tipped spring bar tool to compress and remove the spring bars securing the strap to the lugs. Insert the tip into the small notch on the side of the lug, compress the spring bar and slide the strap free. The process is fully reversible and does not require a watchmaker. It is advisable to work on a soft surface to avoid scratching the case.

Yes. Any strap with a 22 mm attachment width and standard length (approximately 120 mm long + 75 mm short) is compatible with this model. MilanoStraps offers a curated selection of handcrafted 22 mm straps in alligator leather, vegetable-tanned calfskin, shell cordovan and rubber, all designed to fit the Avenger's lug configuration correctly.

The lifespan of a leather strap depends on the material, care and frequency of use. A quality vegetable-tanned calfskin strap, kept away from water and heavy perspiration, typically lasts between 2 and 4 years. Shell cordovan, owing to the density of its fibres, can exceed 5 years with proper maintenance. It is advisable to avoid prolonged contact with water, sunscreen and sweat, and to apply a silicone-free leather conditioner periodically.
