Strap for Chronomat B01 42 NFL New York Giants / Rouleaux

The lug width of the Breitling Chronomat B01 42 AB01342B1CAA1 is 22 mm. This measurement is consistent across the entire Chronomat 42 family and should be verified with a digital calliper placed perpendicular to the case axis between the lugs. Confirming this dimension before purchasing any aftermarket strap is essential to ensure a correct fit.

The most suitable straps for the Breitling Chronomat B01 42 are: grained calf leather for an aeronautical aesthetic faithful to the model's origins, matt alligator for formal occasions, vulcanised rubber for intensive sporting use, and heavy nylon NATO for those prioritising lightness. The material choice should respect the technical character of the watch and complement the brushed steel finish of the case.

To replace the strap on a Breitling Chronomat B01 42, you will need a spring bar tool to release the spring bars housed within the lugs. The Chronomat's lugs feature lateral access holes that facilitate removal. Place the watch face-down on a soft surface, release the buckle-side spring bar first, then the case-side, and replace the spring bars if they show signs of wear before fitting the new strap.
