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

The lug width of the Breitling Colt A1338811/BD83/105X/A20BA.1 is 22mm. This measurement should be taken using a digital calliper positioned internally between the two lugs, at the narrowest point, parallel to the case. Respecting this measurement is essential to ensure a correct and secure strap fitting.

For the Breitling Colt 44mm, the best strap depends on intended use. Belly alligator leather is ideal for formal occasions, complementing the brushed steel finishes. Vegetable-tanned calf leather develops a personal patina over time and suits everyday wear. Ballistic nylon NATO straps maintain the instrument-grade sporting character of the watch, whilst vulcanised rubber is the most coherent choice for marine or high-humidity environments.

The strap is removed using a flat-tip spring bar tool or a dedicated lever instrument, applying pressure to the spring bar that connects each strap half to the case lugs. It is advisable to work on a soft surface to protect the steel from scratches. The 22mm spring bar must be fitted into the new strap before mounting it onto the watch.

Yes. Any strap with a 22mm lug width and standard spring bars is compatible with the Breitling Colt A1338811/BD83/105X/A20BA.1. Milano Straps offers a selection of handcrafted Italian 22mm straps in various materials and finishes, compatible with this Breitling reference and suitable for use with both a classic buckle and a deployant clasp.

The lifespan of a leather strap depends on the quality of the hide, care, and intensity of use. A quality vegetable-tanned calf strap, worn daily and kept away from moisture, typically lasts between 18 and 36 months. Alligator leather, being denser and more resilient, can exceed 3 to 4 years with regular maintenance. It is recommended to avoid prolonged contact with water and perspiration, and to apply a leather conditioner periodically.
