Strap for Colt Chronograph Automatic Stainless Steel / Stratus Silver / Calf / Folding

The lug width of the Breitling Colt A1338811/G804/438X/A20D.1 is 22mm, measured at the attachment point between the case lugs. This is the dimension to specify when ordering a compatible aftermarket strap.

For a tool watch of the Colt's character, the most coherent options are: ballistic nylon NATO for intensive sporting use, vegetable-tanned calfskin leather for daily wear with developing patina, flat-scale alligator for formal settings, and vulcanised rubber for aquatic use. The ideal choice depends on your primary wearing context.

The strap is removed by depressing the spring bars using a dedicated springbar tool or a flat-blade watchmaker's screwdriver. It is advisable to work on a soft surface to prevent scratching the lugs. Standard 22mm spring bars are compatible with the vast majority of aftermarket straps available for this reference.

Yes. Any strap with a 22mm attachment width is technically compatible. milanostraps.it offers a curated selection of handcrafted straps in leather, alligator, NATO and rubber, specifically filtered by 22mm lug width and suitable for the Colt both aesthetically and dimensionally.

A quality leather strap — vegetable-tanned calfskin or alligator — typically lasts between 18 and 36 months with daily wear, depending on exposure to perspiration, water and heat. Regular conditioning with a leather-specific cream significantly extends the strap's lifespan. Casati Milano straps carry an 18-month warranty against manufacturing defects.
