Strap for Colt 44 Automatic Volcano Black / Rubber

The Breitling Colt A1738811.BD44.227S features a lug width of 22mm. This measurement is taken with a calliper placed between the two lugs, flush against the case. It is one of the most common dimensions in the sport-professional category, ensuring wide availability of quality aftermarket straps.

The ideal choice depends on use: for an operational or everyday profile, a ballistic nylon NATO or vulcanised rubber strap offers resilience and practicality. For a more refined register, vegetable-tanned calf leather or matte alligator with contrast stitching complement the 44mm steel case without compromising its technical character. In all cases, the strap width must be 22mm at the lug.

The strap is replaced by removing the spring bars that secure it to the case lugs. Use a bifurcated springbar tool, inserting it into the lateral slot of each lug to compress and release the bar. Care should be taken to avoid scratching the stainless steel case. Alternatively, Casati Milano offers a professional strap-fitting service at its Milan atelier.

Yes. Any strap with a 22mm lug width and standard spring bars is compatible with the Breitling Colt A1738811.BD44.227S. Milano Straps offers a handcrafted selection in leather (calf, alligator, shell cordovan), ballistic nylon NATO and rubber, all made to 22mm lug width and available with various buckle or deployant clasp options.

The lifespan of a leather strap depends on the material, frequency of use and exposure to perspiration and moisture. A quality vegetable-tanned calf strap worn daily typically lasts 18 to 24 months. Alligator, owing to the natural grain structure and greater fibre density, can exceed three years with proper care. All Milano Straps straps carry an 18-month warranty against manufacturing defects.
