Strap for Chronomat Colt 41 Automatic Tempest Grey / Bracelet

The Breitling Colt A17313101F1A1 features a standard lug width of 20 mm. This is one of the most common sizes in the industry, offering a broad selection of aftermarket straps in leather, NATO, rubber or metal without any modifications required.

The ideal choice depends on the occasion. For a dressy setting, a vegetable-tanned alligator strap in 20 mm complements the satin-finished steel beautifully. For daily sport use, box-calf leather or vulcanised rubber offer durability and comfort. A ballistic nylon NATO strap remains the most faithful option to the model's aviator heritage.

Use a spring bar tool, inserting the forked tip into the lug hole or compressing the spring bar laterally to release it. Work on a soft watch cushion to protect the case and caseback from scratches. If in doubt, any watchmaker or the Casati Milano atelier can perform the swap in minutes.

Yes. Any standard straight-ended 20 mm strap is compatible with this reference. Milanostraps.it offers a curated selection of handcrafted 20 mm straps in leather, rubber and nylon made by Casati Milano atelier or sourced from premium manufacturers, all fully compatible with the Breitling Colt.

Longevity depends on leather type and usage. A quality vegetable-tanned calf strap worn daily and kept away from excessive moisture typically lasts 2 to 4 years. Shell cordovan and alligator, though more expensive initially, tend to last longer and develop a distinctive patina over time. Casati Milano straps come with an 18-month manufacturing warranty.
