Strap for Navitimer 1 B01 Chronograph 46 Red Gold / Silver / Croco / Pin

The Breitling Navitimer RB0127121G1P1 has a lug width of 24mm. This is a non-standard dimension compared to the more common 20–22mm calibres, so it is essential to verify this measurement before purchasing any aftermarket strap. Use a millimetre calliper to measure the internal distance between the two case lugs to confirm compatibility.

For an 18kt red gold case, the most coherent materials are alligator leather in bordeaux or dark cognac tones, shell cordovan in whisky or butter, and black vegetable-tanned calf leather for a more formal contrast. A deployant clasp in rose gold completes the stylistic consistency. All these options are available in 24mm on milanostraps.it or can be crafted bespoke at Casati Milano atelier.

Strap replacement requires a spring bar tool to remove the spring bars securing the strap to the 24mm lugs. Place the case on a watch cushion to avoid scratching the red gold. The operation is fully reversible and does not require opening the case or interfering with seals or water resistance.

Yes. Any strap with a 24mm lug width is technically compatible with the Navitimer RB0127121G1P1. milanostraps.it offers a curated selection of handcrafted leather, rubber and textile straps specifically in 24mm. For a bespoke solution with individual leather selection and personalisation, Casati Milano atelier produces made-to-measure straps with an 18-month manufacturing guarantee.

Longevity depends on the material and wear habits. A quality alligator or shell cordovan strap, worn daily in rotation, can last three to five years whilst retaining structural and aesthetic integrity. Vegetable-tanned calf leather typically lasts two to three years. Prolonged exposure to perspiration, water and heat accelerates deterioration: immersion should be avoided and leather conditioned periodically with appropriate products.
