Strap for Navitimer 01 43 Stainless Steel / Battle of Britain / Bracelet

The lug width of the Breitling Navitimer AB01208U/BE28/447A is 22 mm. This measurement is taken between the inner edges of the lugs and is the key specification for selecting a compatible aftermarket strap.

For the Navitimer 43mm with Calibre B01, vegetable-tanned alligator or matte calfskin straps are the most coherent choice given the watch's instrument-focused aesthetic. Ballistic nylon NATO straps suit sporting or aviation use, whilst a brushed steel deployant clasp maintains chromatic consistency with the stainless steel case and simplifies daily fastening.

To replace the strap on the Navitimer, the spring bars securing it to the lugs must be removed using a spring bar tool or a fork-tip screwdriver. It is advisable to have the operation carried out by a watchmaker or experienced strap maker to avoid scratching the stainless steel case. With the correct tools, the procedure typically takes only a few minutes.

Yes, a wide range of aftermarket straps is available to fit the 22 mm lug width of the Breitling Navitimer. Milano Straps offers a curated selection of handcrafted straps in alligator, calfskin, rubber and nylon, all available in 22 mm and designed to fit the Navitimer's lugs without any modification to the original spring bars.

The lifespan of a leather strap depends on the quality of the hide, the tanning process and intensity of wear. A high-quality vegetable-tanned alligator strap, properly maintained — avoiding prolonged moisture exposure and conditioning regularly — can last between three and seven years whilst retaining its structural integrity and appearance. Milano Straps straps carry an 18-month warranty against manufacturing defects.
