Strap for Avenger II Seawolf Stainless Steel / Volcano Black / Calf / Pin

The lug width of the Breitling Avenger A1733110/BC30/437X/A20BASA.1 is 22mm. It should be measured using a digital calliper positioned inside the lugs, between the two opposing walls. Any strap with a 22mm attachment is compatible, provided the springbars used have the correct diameter (1.8mm recommended) and appropriate length.

For the Breitling Avenger A1733110/BC30/437X/A20BASA.1, the most coherent materials are vegetable-tanned Tuscan calf leather for everyday use, matte-finish alligator leather for a more refined look, and heavy nylon or shell cordovan NATO straps for sporting or operational contexts. In all cases, the correct width is 22mm, and glossy finishes should be avoided to respect the instrumental character of this watch.

To replace the strap on the Breitling Avenger A1733110/BC30/437X/A20BASA.1, a fine-tipped springbar tool is required. Insert the tip into the springbar slot, compress the spring towards the inside of the lug, and slide it out laterally. Repeat the same procedure for the second springbar. It is advisable to work on a soft surface to avoid scratching the case. Solid steel springbars with a flanged head, 22mm in length, are recommended for optimum retention.

The lifespan of a leather strap depends primarily on the quality of the hide and daily care. A high-quality vegetable-tanned calf leather strap, treated periodically with natural wax and kept away from prolonged moisture, has a useful life of 2–4 years of daily wear. Alligator leather, due to the more compact structure of its grain, tends to last longer under the same conditions. Casati Milano offers an 18-month guarantee against manufacturing defects on all its straps.
