Strap for Navitimer B01 Chronograph 46 Stainless Steel / Green / Alligator - Folding

The lug width of the Breitling Navitimer AB0137241L1P1 is 24mm. This dimension was proportioned by the manufacturer to the 46mm case diameter to ensure visual balance and wearing comfort. To verify the lug width of your Navitimer, use a ruler and measure the distance between the two side lugs of the case (not from edge to edge of the lug itself). All straps for this size will be compatible without adapters or modifications.

For the Navitimer AB0137241L1P1, we recommend materials that emphasize its aeronautical vocation: dark brown alligator for a refined office aesthetic, vegetable-tanned calf for a vintage patina style, or nylon NATO if you wish to maintain the original sporty character. The choice depends on daily use and the aesthetic context you prefer: leather for elegance, fabric for practicality.

To change the strap on the Navitimer AB0137241L1P1 (24mm lug width), use a spring bar tool to gently remove the elastic pins that secure the strap to the case. Remove the old strap and align the holes of the new one with the lateral elastic pins. Push the new strap until you hear a click. If you are unsure of the procedure, entrust the operation to a professional watchmaker to avoid damage.

Any strap with a 24mm lug width is compatible with the Navitimer AB0137241L1P1. The artisanal straps from milanostraps.it for 24mm lugs have been tested on this model and offer complete customization of material, colour, finish and stitching. The Casati Milano atelier also creates bespoke straps with direct selection of leather and personalised details, ensuring complete compatibility.

The lifespan of a leather strap for the Navitimer depends on use, climate and the quality of the tanning. A high-quality alligator or calf strap can last 3-5 years with daily use and regular maintenance (monthly cleaning, protection from excessive sweat and humidity). Vegetable-tanned leather develops patina over time, improving aesthetically. Milanostraps.it straps benefit from an 18-month warranty. Replacement is always possible with the same model to maintain aesthetic consistency.
