Strap for Avenger II GMT Stainless Steel / Volcano Black / Calf / Folding

The lug width of the Breitling Avenger A3239011/BC34/438X/A20D.1 is 22mm. This measurement refers to the internal distance between the two case lugs and can be verified with a millimetre calliper. Any 22mm strap is compatible with this reference.

Given the instrument-oriented character of this 43mm GMT, the most coherent strap choices are: a ballistic nylon NATO strap for sport and aviation use, a vegetable-tanned alligator strap with a matte finish for formal settings, and a vulcanised rubber strap for water or high-heat environments. A deployant clasp is recommended on any leather strap to preserve its shape over time.

Strap replacement is carried out via the spring bars located within the case lugs. Using a fine-tipped spring bar tool, compress the bar inward towards the lug hole until it releases. It is advisable to work on a soft surface to prevent scratches to the case. For NATO straps, the spring bars remain fixed and the strap threads beneath the case.

Yes. Any strap measuring 22mm at the lug end is technically compatible with the Breitling Avenger A3239011/BC34/438X/A20D.1. Milano Straps offers an extensive selection of handcrafted leather, nylon and rubber straps in 22mm, with a choice of finishes and buckle styles. It is also important to check the total strap length (standard: 75mm/115mm) to ensure a proper fit for your wrist circumference.

Strap longevity depends on the material, frequency of use and maintenance. A quality vegetable-tanned alligator strap, used with care and rotated with other straps, can last between 3 and 6 years while retaining its structural integrity and patina. Prolonged exposure to perspiration, water and heat accelerates deterioration. Given the Avenger's 300-metre water resistance, rubber or NATO straps are preferable for intensive marine or sporting use. Milano Straps provides an 18-month warranty against manufacturing defects on all leather straps.
