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

The lug width of the Breitling Avenger A3239011/G778/435X/A20BA.1 is 22mm. This measurement is taken with a digital calliper placed at the inner opening between the lugs, where the strap inserts. The 22mm standard is consistent across the entire 43mm Avenger line, ensuring broad compatibility with quality aftermarket straps.

The ideal choice depends on intended use. For everyday sporting wear, a 22mm ballistic nylon NATO strap honours the watch's aeronautical heritage whilst offering durability and ease of substitution. For formal occasions, an alligator or shell cordovan strap in vegetable-tanned leather creates a refined contrast with the robust steel case. Vulcanised rubber is recommended for humid environments or dynamic activities.

The strap is removed using a fine-tipped springbar tool inserted into the lug hole or the channel between the strap and case. Compressing the springbar ends releases the strap without force. Rest the watch on a soft surface to avoid scratching the bezel or caseback. The entire procedure takes only a few minutes and requires no professional equipment.

Yes. The 22mm lug width is widely standardised, allowing the fitment of high-quality aftermarket straps without adapters. Milano Straps offers a curated selection of hand-crafted 22mm straps made in Italy, compatible with the Avenger's lug configuration. It is advisable to verify strap length (standard 120/75mm for average wrists) and heel thickness, which should not exceed 4.5mm to ensure a correct fit between the lugs.

The lifespan of a leather strap depends on hide quality, tanning method and daily use. A quality vegetable-tanned calfskin strap, properly maintained with leather conditioner every three to four months and kept away from direct heat, can last three to five years whilst retaining structural integrity. Alligator or shell cordovan straps, due to their denser fibre structure, tend to last longer and develop a distinctive patina. Prolonged exposure to water or perspiration accelerates deterioration; in such conditions, alternating with a rubber or NATO strap is strongly advisable.
