Strap for Navitimer B01 Chronograph 41 Stainless Steel / Japan

The Breitling Navitimer AB01393A1Q1 features a lug width of 14mm. This measurement refers to the internal gap between the two lugs at the point of attachment to the case and should be verified with a digital calliper to ensure compatibility with any aftermarket strap.

For a 41mm Navitimer with its instrument-oriented character, a Hornback alligator strap in black or tobacco brown strikes the most balanced combination of elegance and aesthetic coherence. Shell cordovan in Havana or midnight blue is a refined alternative for those seeking a natural patina over time. For sporting use, a nylon NATO or vulcanised rubber strap are functionally sound options.

To replace the strap, a fine-tipped spring bar tool is required. By inserting the tool into the lateral slot of the lug, the inner spring bar is compressed and the strap is released. The procedure is repeated on both lugs. With 14mm lugs and standard spring bars, the operation takes under two minutes without risk of scratching the case, provided a tool with a plastic protective tip is used.

Yes. Any strap with a 14mm attachment width is technically compatible with the Navitimer AB01393A1Q1. milanostraps.it offers a dedicated selection of 14mm straps in leather, shell cordovan, NATO and rubber, handcrafted and tapered at the ends for precise fitting into Breitling lugs.

The longevity of a leather strap depends on the material and frequency of use. A quality vegetable-tanned calfskin strap, with routine care (conditioning cream every 3–6 months and protection from moisture), typically lasts 2–4 years with daily wear. A shell cordovan or high-grade alligator strap can exceed 5–7 years, owing to the density of the fibre and the protective finish of the surface layers.
