Strap for Navitimer B01 Chronograph 41 Stainless Steel / Black / Bracelet

The lug width of the Breitling Navitimer AB0139211B1A1 is 22mm. This measurement is taken with a calliper positioned perpendicularly to the case, at the narrowest point between the two lugs. Compatible straps typically taper down to 20mm at the buckle end.

The ideal choice depends on the intended use. For formal occasions, an alligator leather strap with contrast stitching complements the brushed steel case elegantly. For daily wear, vegetable-tanned calf leather develops an authentic patina over time. A woven nylon NATO strap is an excellent option for those wishing to emphasise the watch's aeronautical heritage.

Strap replacement requires a springbar tool or a fine flathead screwdriver. Insert the tool into the lug channel to compress and release the springbars. With a little practice the operation takes under two minutes. Any watchmaker or authorised retailer can also perform the swap quickly and free of charge.

Yes. The standard 22mm lug width ensures broad compatibility with quality aftermarket straps. Milano Straps offers a curated selection of handcrafted 22mm straps in leather, NATO, and technical materials, produced using the same artisanal techniques as premier ateliers, without the branded premium.

Lifespan depends on the material and care routine. A well-maintained vegetable-tanned calf strap typically lasts 2–4 years with daily wear. Shell cordovan and alligator, owing to their denser fibre structure, can last considerably longer. Minimising prolonged contact with perspiration and moisture will significantly extend the strap's life.
