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

The lug width of the Breitling Avenger A3239011/G778/434X/A20D.1 is 22mm. This measurement should be taken with a digital calliper directly between the case lugs at the attachment point, ensuring precise compatibility with any aftermarket or bespoke strap.

For the Avenger GMT, the choice depends on intended use: vegetable-tanned Tuscan calf leather is ideal for mixed formal-casual wear and develops an authentic patina over time; hornback alligatore grain suits more formal occasions; FKM rubber is recommended for intensive or marine use; ballistic nylon NATO maintains the model's military heritage. All available in 22mm at Milano Straps.

The strap is removed using a flat-tip springbar tool, applying gentle leverage on the springbars connecting the strap to the case lugs. Care should be taken not to scratch the satin-finished steel surfaces; it is advisable to protect the case with masking tape during the operation.

The lifespan of a leather strap depends on the tanning quality, usage, and maintenance. A quality vegetable-tanned calf strap, kept away from prolonged water exposure and treated periodically with leather conditioner, typically lasts 2–4 years with daily wear. Grade-A alligator straps can exceed 5 years. Milano Straps provides an 18-month guarantee against manufacturing defects.
