Strap for Colt Chronograph Volcano Black / Bracelet

The Breitling Colt A73388111B1A1 has a lug width of 22mm. This measurement should be taken directly between the lugs on the case using a digital calliper, with the tips positioned at the inner contact points of the lugs. All aftermarket straps in 22mm are compatible with this reference.

For the Colt A73388111B1A1, a vegetable-tanned calf leather strap in brown or black strikes the right balance with the professional character of the stainless steel case. Alligator leather suits more formal occasions, while NATO nylon or vulcanised rubber are preferable in sports or aquatic environments. A stainless steel deployant clasp in 22/20mm maintains material consistency with the case.

To replace the strap on the Colt A73388111B1A1, you will need a spring bar tool with a thin tip. Insert the tool into the spring bar slot on the lug, compress the spring-loaded ends, and slide the strap free. For reassembly, insert the 22mm spring bar through the strap loop first, then hook both ends into the lug slots. The procedure can be completed independently within a few minutes.

Yes: any standard 22mm strap is compatible with the Colt A73388111B1A1, provided the spring bars are of adequate length for Breitling lugs (generally 20–22mm usable length). Milano Straps offers a curated selection of handcrafted 22mm straps in calf leather, alligator, shell cordovan and rubber, available bespoke or ready to ship online.

The lifespan of a leather strap on the Colt A73388111B1A1 depends on the leather grade and frequency of use. A quality vegetable-tanned calf strap typically lasts 2–4 years with daily wear, developing a distinctive patina over time. Prolonged exposure to water and perspiration accelerates deterioration: for a sports-oriented chronograph, rotating between two straps or using rubber in humid conditions is advisable. Casati Milano straps carry an 18-month warranty against manufacturing defects.
