Strap for Colt Chronograph Automatic Blacksteel / Volcano Black / Rubber

The lug width of the Breitling Colt M1338810.BF01.227S is 22mm. This measurement is taken between the two horizontal lugs using a calliper and determines compatibility with any aftermarket or original strap.

It depends on intended use. For sport or outdoor contexts, a resilient nylon NATO or a vulcanised rubber strap in 22mm is the most coherent choice for the Colt's professional character. For urban wear, a matte calf leather or vegetable-tanned alligator strap complements the stainless steel case without compromising its technical identity.

The strap is removed by releasing the spring bars using a flat-tip spring bar tool or a dedicated lug tool. The 22mm spring bars should be extracted carefully to avoid scratching the lugs. The operation takes approximately two minutes and does not require a watchmaker.

Yes. Any strap with a 22mm attachment is compatible with the Breitling Colt M1338810.BF01.227S. Milano Straps offers a curated selection of handcrafted leather, nylon and rubber straps, made with the same constructive care as originals but with full customisation of material, colour and stitching.

The lifespan of a leather strap depends on the quality of the hide, the tanning process and daily use. A quality vegetable-tanned leather strap, used with care and not regularly exposed to water, typically lasts between 2 and 5 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects and are crafted from hides selected for long-term durability.
