Strap for Colt Chronograph Automatic Stainless Steel / Volcano Black / Calf / Pin

The Breitling Colt A1338811/BD83/433X/A20BA.1 has a lug width of 22mm. This measurement refers to the internal distance between the two lugs at the strap attachment point and must be matched precisely to ensure a correct and secure fit.

For the 44mm Colt, the most suitable materials are vegetable-tanned calf leather for versatile daily use, alligator leather for formal occasions, nylon NATO for faithfulness to the aeronautical heritage, and vulcanised rubber for sport or aquatic use. A brushed steel deployant clasp is recommended to maintain visual consistency with the case finish.

To replace the strap on a Breitling Colt, use a fine-tipped spring bar tool. Insert the tip into the lug slot, compress the spring bar and slide the strap free. Fit the new 22mm strap using the same spring bars or new ones of compatible diameter and length. The operation takes approximately two minutes per side and requires no professional equipment.

Yes. Any standard 22mm strap is compatible with the Colt A1338811/BD83/433X/A20BA.1, provided the spring bars are of the correct diameter for Breitling lugs. Milano Straps offers a curated selection of handcrafted 22mm straps made specifically for watches of this size, with lengths and thickness proportioned to the 44mm case.

The lifespan of a leather strap depends on material, tanning method and usage. A quality vegetable-tanned calf leather strap, with regular conditioning and rotation with other straps, maintains structural and aesthetic integrity for 3–5 years. High-grade alligator can exceed 7 years. Frequent exposure to perspiration, water or UV light accelerates deterioration; in such cases, rubber or NATO straps are the more practical choice.
