The Avenger II GMT Stainless Steel in Volcano Black is a 43mm professional tool watch from Breitling's Chronospace Military collection. Reference A3239011/BC34/112X/A20D.1 features a Breitling Caliber 32 automatic movement with COSC certification and independent 24-hour GMT hand for simultaneous dual time-zone reading. The 316L stainless steel case includes screw-down crown and caseback, bidirectional ratchet bezel, and 300-meter water resistance per ISO 6425. Strap size is 22mm with straight, slightly tapered lugs. High-intensity SuperLuminova C3 indices and military-tone dial minimize reflections in low-visibility conditions.

Frequently asked questions

What is the lug width of the Breitling Avenger A3239011/BC34/112X/A20D.1?

The lug width of the Breitling Avenger A3239011/BC34/112X/A20D.1 is 22mm. This should be measured using a digital calliper placed inside the lugs, in contact with the spring bars. Any strap with a 22mm attachment width is compatible with this reference.

What is the best strap for the Breitling Avenger A3239011/BC34/112X/A20D.1?

The ideal choice depends on context. Vegetable-tanned alligator leather in black or dark brown enhances the professional character of the Avenger with a refined open-pore grain texture. For sport or wet environments, a vulcanised rubber or ballistic nylon NATO strap is the more practical option. A brushed steel deployant clasp is recommended across all materials for its rapid release mechanism and even pressure distribution.

How do I change the strap on a Breitling Avenger A3239011/BC34/112X/A20D.1?

Strap replacement requires a fine-tipped springbar tool inserted into the recessed lug slots. Compress the spring bar from both ends and slide the strap free. The Avenger's lugs have a straight profile: insert the new 22mm strap with the spring bar slightly compressed, then release it into position. No case disassembly is required; the operation takes approximately two minutes with the correct tool.

Are there aftermarket straps compatible with the Breitling Avenger A3239011/BC34/112X/A20D.1?

Yes. Any strap with a standard 22mm attachment is technically compatible. For an artisanal result, milanostraps.it offers straps in Tuscan leather, alligator, and calfskin, handcrafted for 22mm lugs with finishes consistent with the Avenger's military aesthetic: painted edges, contrast stitching, and a fixed keeper in matching leather.

How long does a leather strap last on a Breitling Avenger A3239011/BC34/112X/A20D.1?

Longevity depends on the leather type and conditions of use. A vegetable-tanned calfskin strap, worn daily and conditioned periodically with neutral wax, will maintain structural integrity for two to four years. Alligator leather, owing to its dense grain, tends to last longer but is susceptible to prolonged moisture. For sport use or high perspiration, rubber or NATO straps are preferable. Casati Milano provides an 18-month warranty against manufacturing defects on all its straps.
