Strap for Avenger Automatic 45 Seawolf Stainless Steel / Yellow / eComm Exclusive

The Breitling Avenger A17319101I2X1 features a lug width of 22mm. This measurement should be taken with a digital calliper by measuring the internal gap between the two lugs on the case — not the external diameter of the lug tips. Using a strap with an exact 22mm attachment is essential for a precise and secure fit.

For the Avenger A17319101I2X1, a vegetable-tanned calf leather strap is the most balanced choice: it develops an authentic patina over time, is robust, and fits the 22mm lugs with a saddle profile. For more formal settings, an alligator strap with centred grain or a shell cordovan offers a significant quality upgrade. For sport use or wet environments, a ballistic nylon NATO or a vulcanised rubber tropical strap are the most functional alternatives.

To replace the strap on the Avenger A17319101I2X1, you will need a fine-tip spring bar tool. Compress the spring bar inside the lug, slide out the old strap, and insert the new one by snapping the spring bar into position. The operation takes only a few minutes but requires care to avoid scratching the steel lugs. Casati Milano also offers an in-person strap change service by appointment.

Yes, the aftermarket offers a wide selection of straps compatible with the 22mm lug width of the Avenger A17319101I2X1. MilanoStraps provides handcrafted straps in leather, alligator, shell cordovan, and rubber, made to the same dimensional specifications as original Breitling straps. It is important to verify that the chosen strap uses standard 22mm spring bars and that the attachment thickness is compatible with the Avenger lug geometry.

The lifespan of a leather strap depends on the quality of the hide and the intensity of use. A high-quality vegetable-tanned strap, worn daily with proper care — kept away from water and excessive perspiration, stored out of direct sunlight — can last between 2 and 5 years while maintaining structural integrity. Shell cordovan, due to its dense fibre structure, tends to outlast standard calf leather. MilanoStraps provides an 18-month warranty against manufacturing defects on all Casati Milano straps.
