Strap for Navitimer 01 43 Stainless Steel / Black / Alligator / Pin

The Breitling Navitimer AB012012/BB01/743P/A20BA.1 features a standard lug width of 22mm. This measurement refers to the internal distance between the two lugs at the point where the strap attaches to the case, and is the key parameter for selecting a compatible strap. It is advisable to verify this measurement with a digital calliper before purchasing an aftermarket strap.

For the Navitimer AB012012/BB01/743P/A20BA.1, the most suitable materials are vegetable-tanned calf leather in a natural or military grain finish, which develops a patina consistent with the instrument-grade character of the watch, and square-scale alligator for formal occasions. NATO straps in ballistic nylon are the ideal functional choice for intensive daily use. In all cases, the strap should feature flexible ends to conform to the curvature of the lugs.

To replace the strap on the Navitimer AB012012/BB01/743P/A20BA.1, a spring bar tool is required to remove the spring bars from the lugs. Insert the flat tip of the tool into the spring bar slot, compress the spring and slide the strap free. Care should be taken to avoid scratching the case: place the watch on a soft cloth and work in good light. The original 22mm spring bars can be reused if they remain in good condition.

Yes, the aftermarket offers a wide selection of straps compatible with the 22mm lug width of the Navitimer AB012012/BB01/743P/A20BA.1. Milano Straps offers handcrafted straps in Italian calf leather, alligator, shell cordovan and NATO fabric, all made with standard 22mm spring bars and available in various lengths to suit any wrist circumference. Artisan-quality construction ensures a precise fit to the lug geometry.

The lifespan of a leather strap depends on the quality of the hide, the level of care and the intensity of use. A high-quality vegetable-tanned calf leather strap, conditioned with leather cream every two to three months and kept away from prolonged moisture exposure, can last between two and five years. Shell cordovan and alligator straps, owing to the greater density of their fibres, tend to offer a longer service life. Milano Straps products carry an 18-month guarantee against manufacturing defects.
