Strap for Chronomat B01 42 NFL Atlanta Falcons

The lug width of the Breitling Chronomat B01 42 AB01342B1B3S1 is 22mm. This measurement is taken with a digital calliper positioned between the inner faces of the lugs, flush against the case back. Any strap with a 22mm attachment width is compatible without adapters.

The most suitable materials for the Chronomat B01 42 are vegetable-tanned calfskin for everyday wear — it develops a distinctive patina over time — and hand-finished alligator for a formal-sport profile. A ballistic nylon NATO strap is the preferred choice for intensive or marine use, while vulcanised rubber ensures full water resistance. A stainless steel deployant clasp is recommended to preserve the shape of leather straps.

Replacing the strap on the Chronomat B01 42 requires a spring bar tool or a flat-tipped watchmaker's screwdriver. Insert the tool into the side slot of the spring bar, compress the spring, and slide the strap free from the lug. The operation is fully reversible and requires no work on the case or case back. It is advisable to work on a soft surface to avoid scratching the case.

Yes. Any strap with a 22mm lug width is compatible with the Breitling Chronomat B01 42 AB01342B1B3S1, provided the spring bars are of the correct diameter for the lug thickness. Milano Straps offers a curated selection of handcrafted leather, alligator, NATO and rubber straps specifically sized for 22mm lugs, with bespoke customisation available through Casati Milano.

The lifespan of a leather strap depends on the quality of the hide, the craftsmanship and the conditions of use. A quality vegetable-tanned calfskin strap, worn daily with moderate exposure to water and perspiration, typically lasts 2 to 4 years. Hand-finished alligator straps, owing to the density of the fibres and protective finishing, can exceed 5 years of regular use. Milano Straps provides an 18-month guarantee against manufacturing defects on all straps.
