Strap for Colt Automatic

The lug width of the Breitling Colt A1738011G599 is 20 mm. This measurement refers to the internal distance between the lugs and is critical for strap compatibility. A 19 mm or 21 mm strap will not fit without modification.

For the Breitling Colt A1738011G599, the most suitable materials are vegetable-tanned calf leather for daily wear, matte alligator leather for formal occasions, and vulcanised rubber or nylon NATO straps for sport use. Strap choice should reflect the dial colour: dark anthracite or cognac leather pairs well with the blue or black dials typical of the Colt range.

To replace the strap on the Breitling Colt A1738011G599, use a fine-tipped or lever-style spring bar tool. The 20 mm spring bars connecting the strap to the lugs are compressed laterally and removed. No professional tools are required, but it is advisable to work on a soft surface to prevent scratches to the satin-brushed steel case.

Yes. Any strap with a standard 20 mm lug width and spring bar fitting is compatible with the Breitling Colt A1738011G599. Milano Straps offers a curated range of handcrafted Italian straps in 20 mm, made with materials selected to complement the technical character and aesthetics of the Colt case.

The lifespan of a leather strap depends on the material, frequency of use, and exposure to moisture and perspiration. A quality vegetable-tanned calf strap typically lasts 18 to 24 months with daily wear. Alligator leather tends to last longer due to its denser fibre structure. To maximise longevity, avoid prolonged exposure to water and apply a leather conditioner periodically.
