Strap for Chronomat Colt 44 Automatic Blue / Calf / Pin

The Breitling Colt A17388101C1X2 features a 22mm lug width. This specification is determined by the proportions of the 44mm stainless steel case and must be matched precisely when selecting any aftermarket or replacement strap.

For the Colt A17388101C1X2, a vegetable-tanned Tuscan calf leather strap is the most coherent choice: it develops an authentic patina over time and suits the tool watch character of the piece. Hornback alligator with pronounced grain or a ballistic nylon NATO strap are equally valid options, consistent with the professional vocation of this timepiece.

To replace the strap on the Colt A17388101C1X2, a spring bar tool with a fine forked tip is required. Release the spring bars by applying gentle leverage between the lug and the strap, freeing one side at a time. A soft cloth placed under the case is recommended to protect the steel lugs from scratching during the operation.

Yes. Any strap with a 22mm attachment is compatible with the Breitling Colt A17388101C1X2. Milano Straps offers a curated selection of handcrafted leather, alligator, NATO and rubber straps, all produced with a standard 22mm lug end and available in short, regular or long lengths to accommodate any wrist circumference.

The lifespan of a leather strap depends on usage and leather quality. A high-quality vegetable-tanned calf leather strap worn daily and maintained with periodic conditioning cream typically lasts between 2 and 4 years. Alligator or shell cordovan straps, owing to their denser fibre structure, tend to last longer — often 4 to 5 years or more with proper care.
