Strap for Navitimer B01 Chronograph 43 Stainless Steel / Boeing 747 / Bracelet

The Breitling Navitimer AB01383B1G1A1 features 22mm lugs. This measurement should be taken internally between the two lugs using a digital calliper at the springbar seat to ensure full compatibility with any aftermarket strap.

It depends on the intended use. For formal or business settings, vegetable-tanned calfskin in tobacco brown or black complements the blue dial without overpowering it. For sport or everyday wear, a nylon NATO or vulcanised rubber strap offers durability and practicality in keeping with the Navitimer's instrumental character.

The strap is removed and replaced using the springbars — the spring-loaded bars housed within the 22mm lugs. Using a springbar tool, compress the tips of the bar to release the strap from each side. The operation takes approximately two minutes and requires no specialist tools or watchmaker assistance.

Yes. Any strap with a 22mm lug width at the buckle end is technically compatible with the Navitimer AB01383B1G1A1. Milano Straps offers a curated selection of handcrafted 22mm straps in alligator, calfskin, NATO nylon and rubber, available both bespoke and ready-to-ship.

Longevity depends on the material, maintenance and frequency of use. A vegetable-tanned calfskin strap, with regular conditioning (every 2–3 months) and kept away from prolonged moisture exposure, will typically retain its aesthetic and structural integrity for 2–4 years. Alligator leather, owing to its denser fibre structure, tends to last longer under equivalent conditions. Milano Straps straps carry an 18-month guarantee against manufacturing defects.
