Strap for Navitimer B01 Chronograph 41 Red Gold / Silver / Alligator - Folding

The Breitling Navitimer RB0139211G1P1 features a lug width of 14 mm. This is an unusually narrow measurement for a chronograph of this stature, resulting from a deliberate design decision that gives the model a more tapered profile on the wrist. To verify the measurement on your own piece, use a calliper to measure the gap between the two lugs at the point where the strap attaches to the case.

For the Navitimer RB0139211G1P1 in a Red Gold case, a vegetable-tanned alligator strap in dark chocolate or cognac is the most coherent choice: the bombé grain develops a patina over time that complements the warm tone of the red gold. Shell cordovan in a tobacco shade is a more formal alternative. Pure black should be avoided, as it visually flattens the chromatic richness of the red gold. The correct strap width is 14 mm.

The strap on the Navitimer RB0139211G1P1 is secured by standard 14 mm spring bars. To replace it, use a spring bar tool to release the bars from the lugs and fit the new strap. The process takes only a few minutes and does not require a watchmaker, provided care is taken not to scratch the red gold case during the operation.

Yes. Any aftermarket strap with a 14 mm attachment and straight ends is compatible with the Navitimer RB0139211G1P1. Milanostraps.it offers a curated selection of handcrafted 14 mm straps in alligator leather, calfskin, shell cordovan and other materials, finished to a standard befitting the red gold case. A fully bespoke strap can also be commissioned through the Casati Milano atelier.

The lifespan of a leather strap depends on the quality of the hide, frequency of wear, and exposure to perspiration and the elements. A high-quality vegetable-tanned alligator strap, worn regularly but not daily, will maintain its structural and aesthetic integrity for three to five years. Casati Milano straps carry an 18-month warranty against manufacturing defects. To maximise longevity, it is advisable to rotate straps and avoid prolonged exposure to moisture.
