Strap for Navitimer B01 Chronograph 43 Stainless Steel / Silver / Alligator - Folding

The Breitling Navitimer AB0138241G1P1 features a lug width of 22 mm. This measurement is taken with a millimetre calliper positioned between the two lugs of the case, at the point of contact with the strap. Using a strap with a different attachment width would compromise the fit and wearing stability.

The ideal strap for the Navitimer AB0138241G1P1 depends on the intended context. A black or midnight-blue alligator strap enhances the formal register of the chronograph; vegetable-tanned calfskin develops an authentic patina for everyday wear; a nylon NATO strap honours the original tool-watch character; vulcanised rubber suits sporting or marine environments. All options must feature a 22 mm attachment width.

To replace the strap on the Navitimer AB0138241G1P1, use a spring bar tool (fork-tip lever) inserted into the spring bar slot between the lug and the strap. Compress the spring bar, slide out the old strap, and fit the new one using the same bars. Work on a soft surface to avoid scratching the stainless-steel case. If in doubt, the operation can be carried out by a watchmaker or at the Casati Milano atelier.

Yes: any strap with a 22 mm attachment width is compatible with the Navitimer AB0138241G1P1, provided the strap ends are straight (not curved as on certain Rolex sport models). Milano Straps offers a curated selection of handcrafted 22 mm straps in leather, rubber, and textile, produced by Casati Milano using certified materials and hand-stitched finishing.

The lifespan of a leather strap depends on hide quality, daily care, and intensity of use. A high-grade alligator or calfskin strap, treated with appropriate leather conditioners and kept away from prolonged exposure to water and perspiration, will maintain its structural and aesthetic integrity for 2 to 4 years of regular wear. Casati Milano straps carry an 18-month warranty against manufacturing defects.
