Strap for Chronomat Colt 44 Automatic Black / Bracelet

The Breitling Colt A1738810.BG81.173A has a lug width of 22mm. This measurement is taken with a digital calliper at the narrowest point between the two lugs, where the strap inserts. Any standard 22mm strap is compatible with this reference.

For the Colt A1738810.BG81.173A, a 22mm vegetable-tanned calf leather or matte alligator strap best complements the watch's technical and military character. Ballistic nylon NATO straps are ideal for active use, while vulcanised rubber suits aquatic environments. A brushed steel deployant clasp offers optimal security and even pressure distribution across the wrist.

To replace the strap on the Colt A1738810.BG81.173A, use a dedicated springbar tool to remove the springbars anchoring the strap to the lugs. Work on a soft surface to avoid scratching the steel lugs. If you are unfamiliar with the process, it is advisable to consult a watchmaker or follow a reliable technical guide.

Yes, any aftermarket strap with a 22mm attachment width and a straight or slightly tapered profile is compatible with the Breitling Colt A1738810.BG81.173A.

The lifespan of a leather strap depends on leather quality, frequency of wear and exposure to perspiration and water. A high-quality vegetable-tanned calf strap worn daily typically lasts between two and four years, developing an authentic patina over time. Premium alligator leather offers superior longevity. All Casati Milano straps from Milano Straps carry an 18-month production defect warranty.
