Strap for Navitimer B01 Chronograph 41 Red Gold / Blue MOP / S&S Hanoi

The lug width of the Breitling Navitimer RB01392A1C1P1 is 14mm. This measurement is specific to the red gold 41mm variant and differs from larger steel versions, which feature 20mm or 22mm lugs. To measure accurately, place a digital calliper between the case lugs at the strap insertion point, not at the tip.

For an 18-carat red gold case, the most harmonious choice is a hornback alligator strap in bordeaux, cognac or mahogany tones, which complement the warm hue of the red gold. Shell cordovan in havana develops a distinctive waxy patina over time. For everyday wear, vegetable-tanned box-grain calf leather provides durability and a fine texture without competing visually with the busy Navitimer dial.

Changing the strap on a Navitimer requires a fine-tipped springbar tool to release the spring bars from the case lugs. The operation should be carried out carefully to avoid scratching the red gold surfaces; a watch cushion is recommended, and covering the lugs with PTFE tape provides additional protection. The replacement 14mm strap should be fitted ensuring both spring bars click securely into their recesses.

Yes, the aftermarket offers 14mm straps compatible with the Navitimer RB01392A1C1P1. Milano Straps produces bespoke handcrafted straps with the end piece trimmed precisely to 14.0mm for a perfect fit. It is essential not to use straps with 20mm or 22mm attachments, which are incompatible with this version. The buckle or deployant clasp should be selected in red gold PVD or solid red gold to match the case material.

The lifespan of a leather strap depends on the material and care. A high-quality vegetable-tanned alligator strap, kept away from water and heavy perspiration, typically lasts 3 to 5 years with regular wear. Shell cordovan, owing to its densely structured fibres, can last 7 to 10 years. It is advisable to rotate between two straps to reduce wear and to apply a specialist conditioner for exotic leathers periodically.
