Strap for Chronomat 44 Stainless Steel / Diamond / Blackeye Gray / Croco

The lug width of the Breitling Chronomat B01 44 reference AB0110AA.F546.737P is 22mm. This measurement is taken with a vernier calliper between the inner edges of the two lugs, where the strap is fitted. It is one of the most common lug widths found on large-format sport chronographs.

The Chronomat B01 44 pairs particularly well with vegetable-tanned calfskin for everyday wear, square-scale alligator for formal occasions, and rubber for sport or wet environments. A nylon NATO strap reinforces the instrument watch character of the model. A deployant clasp is recommended to maintain visual symmetry with the 44mm case.

The Chronomat B01 44 uses standard spring bar lugs. To replace the strap, use a springbar tool or a flat-blade spring bar tool to compress and remove the spring bars from the lug holes, slide out the existing strap, and fit the new one by re-inserting the spring bars into the lateral holes. Take care not to scratch the case; if in doubt, consult a watchmaker.

Yes. The Breitling Chronomat B01 44 has standard 22mm lugs, making it fully compatible with quality aftermarket straps. Ensure the lug width is 22mm and that the strap length (typically 75mm short end + 115mm long end for average wrists) is appropriate. Milano Straps offers a curated selection of 22mm straps in various materials and finishes.

The lifespan of a leather strap depends on the material and care. A quality vegetable-tanned calfskin strap, conditioned regularly and kept away from water, can last between 2 and 4 years with daily wear. Alligator leather is generally more resistant to deformation but requires the same level of care. Milano Straps straps carry an 18-month warranty against manufacturing defects.
