Strap for Navitimer B01 Chronograph 41 Red Gold / Japan

The lug width of the Breitling Navitimer RB01393A1B1P1 is 14mm. This measurement should be taken with a digital calliper at the point where the strap meets the case, measuring the internal distance between the two lugs. It is important to distinguish this measurement from the buckle-end width, which on tapered straps is typically 12mm.

For a Red Gold 41mm case, the most suitable materials are flat-head alligator with a glossy finish for a formal register consistent with the precious metal, or shell cordovan for those seeking a more personal patina over time. Vegetable-tanned calf leather is ideal for more active daily wear. A deployant clasp in matching red gold completes the pairing with maximum aesthetic consistency.

The strap on the Navitimer RB01393A1B1P1 is secured by standard 14mm spring bars. Replacement requires a spring bar tool or a lug lever: compress the spring bar, remove the old strap, and fit the new one. Care should be taken not to scratch the Red Gold lugs — use a protective cloth and, if in doubt, consult a watchmaker.

The lifespan of a leather strap depends on the material and the care it receives. A quality alligator strap, with regular maintenance and rotation with other straps, can last 3 to 5 years whilst retaining its structural integrity and appearance. Shell cordovan, owing to its density and compactness, tends to last even longer, developing a distinguished patina. Vegetable-tanned straps benefit from conditioning cream applied every six months to preserve the leather fibres.
