Strap for Navitimer B01 Chronograph 41 Stainless Steel / Blue MOP Japan

The Breitling Navitimer AB0139211C2P1 has a lug width of 22 mm. This dimension is dictated by the proportions of the 41 mm case and ensures the correct visual balance between the dial and the strap. Before purchasing any aftermarket strap, always verify the lug width using a digital calliper positioned between the two lugs of the case.

For the Navitimer AB0139211C2P1, vegetable-tanned calf leather with a vintage grain or matte Mississippiensis alligator are the choices most coherent with the chronograph's aviation identity. A nylon NATO strap respects aeronautical tradition, while vulcanised rubber complements the sporty character of the steel case. The correct lug width is 22 mm.

The strap on the Navitimer AB0139211C2P1 is removed using a dedicated springbar tool — a thin-tipped instrument that compresses the spring bars housed in the lugs. Insert the tip into the gap between the lug and the strap, compress the spring bar and slide the strap out laterally. This is a straightforward operation, though care should be taken not to scratch the steel case; placing a soft cloth beneath the case is advisable.

Yes. Any strap with a 22 mm lug width and standard spring bars is compatible with the Navitimer AB0139211C2P1. MilanoStraps offers a selection of handcrafted leather, rubber and nylon straps available in this width. It is also worth checking the spring bar length and the lug radius to ensure a precise fit.

The lifespan of a leather strap depends on the quality of the tanning, daily use and exposure to perspiration and moisture. A quality vegetable-tanned calf strap, used with care and kept away from prolonged water contact, typically lasts between 18 and 36 months. A properly maintained alligator strap can last 3 to 5 years or more. MilanoStraps provides an 18-month guarantee against manufacturing defects on all its straps.
