Strap for Colt Chronograph Stratus Silver / Rubber / Pin

The lug width of the Breitling Colt A7338811/G790/228S/A20S.1 is 22mm. This measurement should be taken internally between the two lugs using a calliper, at the point where they meet the case. This is the correct dimension to specify when purchasing any compatible strap.

The choice depends on the intended use. For heavy daily or sporting use, a nylon NATO strap or vulcanised rubber strap provides robustness and ease of cleaning. For a more formal register, a matte Box Calf or a vegetable-tanned alligator strap develops an elegant patina that complements the satin-finished steel case of this 44mm timepiece.

The strap is replaced using a springbar tool to remove the spring bars securing it to the lugs. The operation takes only a few minutes with the correct tools. It is advisable to protect the case with a soft cloth to avoid scratching the steel during the process.

Yes. Any strap with a 22mm lug width is compatible with this model. Milanostraps.it offers a curated selection of handcrafted 22mm straps in various materials — leather, alligator, NATO, rubber — designed to fit the Colt's lugs precisely without any modification.

Longevity depends on the material and usage. A quality calfskin strap with vegetable tanning, worn daily, has an average lifespan of 2–4 years if kept away from water and excessive perspiration. Alligator leather, thanks to its dense fibre structure, tends to last longer while developing a distinctive patina. Milano Straps provides an 18-month guarantee against manufacturing defects.
