Strap for Navitimer 1 B01 Chronograph 43 Red Gold / Black / Croco / Pin

The Breitling Navitimer RB0121211B1P1 has a lug width of 22mm. This measurement is specific to the 43mm case diameter variant and must be confirmed before purchasing any aftermarket strap. It should be measured with a calliper directly between the two lugs on the case.

For an 18-carat red gold case, alligator leather in cognac, bordeaux or havana tones provides the most coherent pairing with the codes of high watchmaking. Vegetable-tanned calf leather from Tuscan tanneries offers a more restrained but characterful alternative. For sporting use, vulcanised rubber or a heavy-weave 22mm nylon NATO strap is recommended.

Strap replacement is carried out via the spring bars securing the strap to the lugs. A dedicated spring bar tool or a fine flathead screwdriver is required to remove the bars without scratching the red gold lugs. Work on a soft surface and, if inexperienced, consult a watchmaker or the Casati Milano atelier.

Yes. Any 22mm strap with straight or slightly tapered ends is compatible, provided the spring bar length matches the lug spacing (approximately 22mm). Milano Straps offers a dedicated selection of 22mm straps compatible with the Navitimer, handcrafted in Italy.

Longevity depends on leather type, frequency of wear and exposure to perspiration and moisture. A quality alligator strap, properly maintained and rotated regularly, can last 3–5 years or more. Vegetable-tanned calf develops a patina over time and can last equally long if kept dry. Prolonged exposure to sweat is the primary cause of degradation for any leather strap.
