Strap for Chronomat B01 42 NFL Denver Broncos

The lug width of the Breitling Chronomat B01 42 AB01342B1O2S1 is 22 mm. This measurement is taken by placing a millimetre ruler between the lugs at the point where the spring bar sits. It is a standard dimension shared across Breitling's high-end sports chronograph range.

The Chronomat B01 42 pairs well with vegetable-tanned calfskin straps for a tool-watch aesthetic, fine-grain alligator leather for formal occasions, ballistic nylon NATO straps in keeping with its aeronautical heritage, or vulcanised rubber for active use. The correct width is 22 mm, ideally with a steel buckle or deployant clasp.

To replace the strap, use a spring bar tool inserted between the lug and the strap's end piece to compress and release the spring bar. It is advisable to have the first replacement carried out by a watchmaker to avoid scratching the polished lug surfaces. Breitling original spring bars for 22 mm straps have a diameter of 1.8 mm.

Yes. Any strap with a 22 mm lug width is technically compatible with the Chronomat B01 42. Milano Straps crafts bespoke and ready-to-ship straps in Italian leather, rubber and nylon at 22 mm, complete with spring bars and an 18-month production guarantee.

The lifespan of a leather strap depends on leather quality, frequency of use and exposure to perspiration and moisture. A quality vegetable-tanned strap with heat-bonded layers and burnished edges typically lasts between two and four years with daily wear. The patina that develops over time is considered an intrinsic part of the handcrafted product's character.
