Strap for Chronomat Colt 41 Automatic Tempest Grey / Calf / Folding

The lug width of the Breitling Colt A17313101F1X3 is 20 mm. This measurement, taken with a digital calliper between the inner walls of the lugs at the point of strap attachment, determines compatibility with any 20 mm aftermarket strap.

The most suitable straps for the Breitling Colt A17313101F1X3 are: Hornback alligator for formal occasions, vegetable-tanned calf leather for versatile everyday wear, vulcanised rubber for sport or marine use, and ballistic nylon NATO to echo the model's aeronautical heritage. The ideal choice depends on the context of use and personal aesthetic preference.

The strap on the Breitling Colt A17313101F1X3 is replaced by removing the two spring bars that secure it to the case lugs. A fine-tipped spring bar tool is sufficient: compress the spring bar laterally to release it from the lug slot, remove the strap and insert the new one. No professional tools are required, though working on a soft surface is advisable to avoid scratching the case.

Yes. Any standard 20 mm strap with spring bars is compatible with the Breitling Colt A17313101F1X3. Milano Straps offers a selection of handcrafted leather, rubber and textile straps in this exact width, manufactured to a standard comparable to the original Breitling strap.

The lifespan of a leather strap depends on the quality of the tanning process and frequency of use. A good-quality vegetable-tanned calf strap typically lasts 2 to 4 years with daily wear; an alligator strap, owing to its denser fibre structure, can exceed 5 years. Regular exposure to water and perspiration significantly reduces service life: for sport use it is advisable to alternate with a rubber strap.
