Strap for Navitimer 01 43 Red Gold / Black / Calf / Pin

The lug width of the Breitling Navitimer RB012012/BA49/435X/R20BA.1 is 22mm. This measurement is standard across the entire 43mm Navitimer line and should be verified using a digital calliper by measuring the internal distance between the two lugs at the point closest to the case.

For the Red Gold Navitimer, the most suitable strap is a Louisiana alligator with a polished grain in bordeaux, cognac or honey brown tones: the geometric scale texture complements the complexity of the dial while harmonising with the warm chromatic register of the red gold. Alternatively, vegetable-tanned Tuscan calfskin develops a natural patina over time, highly regarded among fine watchmaking enthusiasts.

The strap is removed using a fine-tipped spring bar tool or a standard 1.5mm bar tool, applying gentle pressure on the spring bar within the lug. It is advisable to work on a soft surface to protect the red gold case from scratches. Strap replacement does not require specialist tools, though care should be taken given the precious nature of the case material.

Yes. Aftermarket straps measuring 22mm with straight or slightly tapered ends are compatible with the Navitimer lugs. Milano Straps offers a selection of handcrafted 22mm straps made to order, tapered to 20mm at the buckle end to ensure compatibility with the original Breitling buckle or aftermarket deployant clasps.

The lifespan of a leather strap depends on the quality of the hide and frequency of use. A high-quality vegetable-tanned calfskin strap typically lasts between 18 and 36 months with daily wear; a genuine alligator strap, owing to its denser fibre structure, can exceed 3 to 5 years if regularly conditioned with leather cream and kept away from prolonged exposure to water and perspiration.
