Strap for Chronomat B01 42 NFL New Orleans Saints / Rouleaux

The lug width of the Breitling Chronomat B01 42 AB01342B1B4A1 is 22 mm. This measurement is taken with a digital calliper across the inner distance between the two lugs, parallel to the bezel. It is a standard size within high-end sport watchmaking, compatible with a wide range of aftermarket straps.

The ideal choice depends on the intended use. For sport or daily wear, perforated Italian calf leather or vulcanised rubber are the most coherent options given the model's aeronautical character. For business-casual settings, a vegetable-tanned alligator strap in navy blue or cognac complements the steel case without undermining the instrument's identity. A ballistic nylon NATO strap is the preferred option for travel and summer use.

The Breitling Chronomat B01 42 uses standard 22 mm spring bars. To replace the strap, insert a springbar tool into the lug slot, compress the bar and slide the strap free. No specialist tools are required; the operation can be performed independently in a few minutes, taking care not to scratch the case lugs.

Yes. Any strap with a standard 22 mm spring bar attachment is compatible with the Breitling Chronomat B01 42 AB01342B1B4A1. Milanostraps.it offers a curated range of handcrafted straps in leather, alligator, perforated calf, NATO and rubber, all made in Italy from selected materials and available in 22 mm.

The lifespan of a leather strap depends on material quality, frequency of wear and exposure to perspiration and water. A quality vegetable-tanned calf strap worn daily typically lasts 18 to 24 months. A vegetable-tanned alligator strap, being denser and more resilient, can exceed three years with routine maintenance (a conditioning cream applied every three to four months). Avoiding water immersion significantly extends the strap's service life.
