To replace the strap on the Breitling Colt A7438911/C913/213X/A16BA.1, use a spring bar tool to release the standard spring bars housed within the 18mm lugs. Carefully lever the tool into the spring bar groove, compress and remove. Fit the new strap ensuring both spring bars engage fully before wearing the watch.

The lifespan of a leather strap depends on hide quality and daily care. A well-made vegetable-tanned calf strap, kept away from prolonged moisture and perspiration, typically lasts between two and five years. Shell cordovan or alligator straps, owing to their denser fibre structure, tend to develop a fine patina and last considerably longer with proper maintenance.
