Strap for Navitimer B01 Chronograph 43 Stainless Steel / Korea

The Breitling Navitimer AB01381B1G1 has a lug width of 22 mm. This is the standard measurement for 43 mm Navitimer chronographs and allows for a wide range of quality aftermarket straps in leather, synthetic materials, or fabric.

The most suitable materials for the Navitimer AB01381B1G1 are alligator leather for formal occasions, vegetable-tanned calf leather for everyday wear, and nylon NATO straps to reference the model's aeronautical heritage. The choice depends on use context and dial colour: dark tones and pronounced textures work best with black or blue dials.

The strap is removed using a spring bar tool inserted into the inner channel of the lugs. Standard 22 mm spring bars are compatible. The operation takes approximately two minutes and requires no professional tools, though working on a soft surface is advisable to prevent scratches to the case and crystal.

Yes. Any strap with a 22 mm lug width is technically compatible with the Navitimer AB01381B1G1. Milano Straps offers a selection of handcrafted straps in various materials — alligator, calf, shell cordovan, NATO, rubber — all produced with spring bars included and ready to fit.

Longevity depends on the material, frequency of use, and exposure to perspiration and moisture. A well-maintained vegetable-tanned calf strap typically lasts 2–4 years; a top-grade alligator strap can exceed 5–7 years. Casati Milano straps carry an 18-month guarantee against manufacturing defects. Rotating between at least two straps and storing them in a dry place will significantly extend their lifespan.
