Strap for Avenger II GMT Stainless Steel / Mariner Blue / Calf / Folding

The lug width of the Breitling Avenger A3239011/C872/434X/A20D.1 is 22mm. This measurement is taken with a digital calliper positioned inside the two lugs at the strap attachment point. It is a standard dimension in high-end sports watchmaking, ensuring broad compatibility with aftermarket straps.

The ideal choice depends on context. For professional or semi-formal settings, a large-grain alligator strap with a matte finish complements the 43mm case without undermining its instrumental character. For intensive daily wear, vegetable-tanned calfskin develops a personal patina over time. For aquatic or sporting use, vulcanised rubber at 22mm is the most coherent option given the Avenger's technical specifications.

The strap is removed using a fine-tipped spring bar tool or a 1.5mm flat-head precision screwdriver, applying gentle pressure on the spring bar housed within the lugs. It is advisable to work on a soft surface to protect the case. Standard 22mm spring bars are approximately 20–21mm in length; always verify compatibility before purchasing replacement bars.

Yes, the 22mm lug width is one of the most common in sports watchmaking, offering a wide selection of aftermarket handcrafted straps. Milanostraps.it provides a dedicated range of 22mm straps in leather, NATO, rubber and technical materials, all made in Italy and fully compatible with the Breitling Avenger without the need for adapters.

Longevity depends on leather quality and maintenance. A high-quality vegetable-tanned calfskin strap worn daily with normal exposure to perspiration and moisture typically lasts 18 to 36 months. Using a deployante clasp, which reduces mechanical stress on the leather at each opening, extends lifespan considerably. Alligator straps, with proper care, can easily exceed three years of daily use.
