The Breitling Colt Chronograph Automatic A1338811/G804/433X/A20BA.1 is a professional instrument watch with a 44mm stainless steel case and 22mm lug width. It features the Breitling Caliber 13 automatic movement (derived from Valjoux 7750), offering hours, minutes, small seconds at 9 o'clock, date, and chronograph function.

Frequently asked questions

What is the lug width of the Breitling Colt A1338811/G804/433X/A20BA.1?

The lug width of the Breitling Colt A1338811/G804/433X/A20BA.1 is 22mm. This measurement refers to the internal distance between the two lugs of the case and is the essential parameter when selecting a compatible replacement strap. Any strap with a 22mm attachment fits this reference directly.

What is the best strap for the Breitling Colt A1338811/G804/433X/A20BA.1?

The ideal strap for the Breitling Colt A1338811/G804/433X/A20BA.1 depends on the intended use. For professional or sport contexts, a nylon NATO or vulcanised rubber strap aligns best with the watch's instrumental character. For daily wear or formal occasions, a vegetable-tanned calfskin or alligator strap fitted with a deployant clasp complements the stainless steel case without undermining the tool-watch aesthetic.

How do you change the strap on a Breitling Colt A1338811/G804/433X/A20BA.1?

To replace the strap on the Breitling Colt A1338811/G804/433X/A20BA.1, a springbar tool is required — a double-tipped instrument used to compress the springbar ends and release them from the lugs. Care should be taken to protect the case and lugs with mylar tape during the operation to avoid scratching. An experienced watchmaker can complete the swap in a matter of minutes.

Are there aftermarket straps compatible with the Breitling Colt A1338811/G804/433X/A20BA.1?

Yes. Any strap with a 22mm lug width is technically compatible with the Breitling Colt A1338811/G804/433X/A20BA.1. Milanostraps.it offers a curated range of handcrafted Italian straps in leather, alligator, calfskin, NATO and rubber, all available in 22mm. The precise artisan construction ensures accurate fitment within the original lugs.

How long does a leather strap last on a Breitling Colt A1338811/G804/433X/A20BA.1?

The lifespan of a leather strap depends on the quality of the hide, maintenance routine and frequency of use. A high-quality vegetable-tanned calfskin strap worn daily and kept away from prolonged exposure to water and perspiration typically lasts between 18 and 36 months. Alligator leather, owing to its dense natural fibre structure, tends to develop a distinguished patina and last considerably longer. Regular application of a leather conditioner and avoiding water contact will extend the strap's service life significantly.
