Strap for Chronomat 44 Stainless Steel / White - Roman / Rubber

The lug width of the Breitling Chronomat B01 44 AB011011/A690/131S is 22 mm. This measurement refers to the internal distance between the two case lugs and is the key parameter for selecting a correctly fitting replacement strap.

The most suitable straps for the Chronomat B01 44 are: vegetable-tanned calfskin for a sport-elegant aesthetic that develops a natural patina over time, square-scale alligator for formal occasions, perforated rally leather to echo the watch's aeronautical and motorsport heritage, or vulcanised rubber for intensive daily wear. A butterfly deployant clasp enhances wrist symmetry and ease of use.

To replace the strap on the Chronomat B01 44, a spring bar tool is required to release the spring bars securing the strap to the lugs. The integrated, downward-angled lugs of this model require careful positioning of the tool to avoid scratching the case. It is advisable to work on a soft surface and, if in doubt, to entrust the task to a qualified watchmaker or authorised retailer.

Yes. The Chronomat B01 44 features standard 22 mm straight-end lugs, ensuring compatibility with a wide range of artisan aftermarket straps. Milano Straps offers leather, alligator, shell cordovan and rubber straps crafted for this case, with customisable finishes and stitching. It is important to confirm that the strap has straight rather than curved ends for a proper fit.

The lifespan of a leather strap depends on the quality of the tanning, daily use and material care. A high-quality vegetable-tanned calfskin strap, used with care to avoid moisture and rotated regularly with other straps, can last between two and five years while maintaining good structural integrity. High-grade alligator straps, owing to the density of their fibres, tend to offer greater longevity. Milano Straps provides an 18-month warranty against manufacturing defects.
