The Heritage

The Navitimer B01 Chronograph 41 Red Gold (ref.

Lug width is 14mm, proportioned to the case diameter and the model's formal tradition.

FAQ

What is the lug width of the Breitling Navitimer RB01393A1B1P1?

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.

What is the best strap for the Breitling Navitimer RB01393A1B1P1 in Red Gold?

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.

How do you change the strap on a Breitling Navitimer RB01393A1B1P1?

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.

Are there aftermarket straps compatible with the Breitling Navitimer RB01393A1B1P1?

Yes, any strap with a standard 14mm spring bar attachment is compatible with the Navitimer RB01393A1B1P1. Milanostraps.it offers a curated selection of handcrafted 14mm straps in various materials and finishes, produced using artisanal techniques and fully compatible with the original Breitling lugs without any adapters.

How long does a leather strap last on a Breitling Navitimer?

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.
