Strap for Colt 44 Automatic Volcano Black / Bracelet

The Breitling Colt A1738811.BD44.173A has a lug width of 22mm. This measurement is taken at the point where the strap meets the case lugs and determines the correct strap size for any replacement or aftermarket option.

Given the technical character of the 44mm Colt, the most fitting options are: vegetable-tanned calf leather for everyday wear, large-grain alligator for formal occasions, nylon NATO for faithfulness to the military heritage, and vulcanised rubber for sport or diving use. All must have a 22mm lug width.

The strap is replaced using a spring bar tool to release the spring bars from the lugs. The operation takes approximately two minutes, but it is advisable to have it carried out by a watchmaker or specialist craftsman to avoid scratching the stainless steel case.

Yes, any strap with a 22mm lug width is technically compatible. Milano Straps offers a curated selection of handcrafted straps — in leather, NATO and rubber — specifically designed for tool watches such as the Colt, with materials and finishes chosen to complement the original aesthetic.

A quality leather strap, whether vegetable-tanned calf or alligator, typically lasts between 2 and 4 years with daily wear, depending on exposure to perspiration, water and UV light. Regular conditioning with appropriate leather products and alternating between two straps can extend its lifespan considerably.
