Strap for Colt Chronograph Automatic Stainless Steel / Mariner Blue / Bracelet

The lug width of the Breitling Colt A13388111C1A1 is 22 mm. This measurement should be taken with a digital calliper applied internally between the two lugs of the case. It is the precise figure required when purchasing any compatible aftermarket strap.

The ideal choice depends on intended use. For formal occasions, a vegetable-tanned alligator strap at 22 mm paired with a steel deployant clasp offers the most refined result. For daily wear, a smooth matte calf leather develops an attractive patina over time. A nylon NATO strap remains the most historically coherent choice given the Colt's aeronautical heritage.

The strap on the Breitling Colt A13388111C1A1 is secured by standard 22 mm spring bars. To replace it, use a spring bar tool or a fine-tipped blade to compress the spring bar laterally, releasing the strap from the lug. No watchmaker intervention is required; the operation takes only a few seconds and is fully reversible.

Yes. Any aftermarket strap with a 22 mm attachment width and standard length (approximately 75 mm short side + 115 mm long side) is compatible with the Breitling Colt A13388111C1A1, provided the spring bars are of adequate diameter for the lugs. Milano Straps offers a curated selection of handcrafted leather, NATO and rubber straps specifically sized for this model.

The lifespan of a leather strap depends on the quality of the hide, maintenance and frequency of use. A quality vegetable-tanned calf strap worn daily and kept away from prolonged moisture typically lasts 2 to 4 years. Alligator leather, being denser and more abrasion-resistant, can exceed 5 years with periodic conditioning using a neutral leather cream.
