Strap for Navitimer B01 Chronograph 41 Stainless Steel / White - Boutique / Bracelet

The Breitling Navitimer AB0139A71G1A1 has a lug width of 22mm. This measurement refers to the internal distance between the case lugs and determines the correct strap width at the point of attachment. At the buckle end, the strap typically tapers to 20mm.

For the Navitimer AB0139A71G1A1, vegetable-tanned Tuscan leather is the most coherent choice given the chronograph's historical character. Alligator leather suits more formal contexts, whilst a ballistic nylon NATO strap references the model's aeronautical origins. Vulcanised rubber is preferable for sporting use or humid environments.

Strap replacement is carried out via the spring bars that secure the strap to the case lugs. Using a dedicated spring bar tool or small lever, compress the spring bar on one side, release it from the lug, and repeat on the opposite side. The operation is straightforward but requires care to avoid scratching the case. Working on a soft surface is strongly recommended.

Yes, any strap with a 22mm attachment width is compatible with the Navitimer AB0139A71G1A1. Milano Straps offers a curated selection of handcrafted 22mm straps made in Italy from selected materials — including calf leather and alligator — designed to integrate seamlessly with the proportions of Breitling's distinctive lugs.

A quality leather strap, properly maintained with nourishing cream and kept away from prolonged exposure to water and perspiration, typically lasts between two and four years with daily wear. Vegetable-tanned straps tend to improve with age, developing an authentic patina, though they remain sensitive to excessive moisture. Rotating between two or three straps considerably extends the lifespan of each one.
