Strap for Chronomat 44 Stainless Steel / Grey / Calf

The lug width of the Breitling Chronomat B01 44 AB011011/M524/435X is 22mm. This measurement is taken with a calliper placed between the inner faces of the lugs at the point where the strap meets the case. It is a standardised dimension across the entire Chronomat 44 family.

The most suitable straps for the Chronomat B01 44 are alligator leather in a matte finish for formal wear, vegetable-tanned calfskin for everyday use, and nylon NATO for sporting activities. The correct width is 22mm. A steel deployant clasp improves both comfort and long-term strap preservation.

The strap is replaced using a flat or curved spring bar tool to release the spring bars connecting the strap to the case lugs. Work on a padded surface to avoid scratching the case. The operation takes approximately two minutes per side and requires no specialist tools.

The lifespan of a leather strap depends on the material, maintenance routine and frequency of use. A quality vegetable-tanned calfskin strap, kept away from water and excessive perspiration and treated periodically with a leather conditioner, will typically last between two and four years. Alligator leather, owing to its denser fibre structure, generally offers greater longevity.
