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

The Breitling Navitimer AB0139211A1P1 features a lug width of 22mm. This measurement is taken with a calliper between the two lugs at the point where the strap is inserted, not across the outer diameter of the case. Any strap with a 22mm attachment is compatible with this reference.

The ideal strap for the Navitimer AB0139211A1P1 depends on context. Vegetable-tanned alligator leather is the most refined and durable option for formal wear; a double-pass nylon NATO strap is truest to the watch's aeronautical heritage; vulcanised rubber suits sporting use or humid conditions. A vintage-style calfskin strap with contrast stitching works well as an everyday choice.

The strap on the Navitimer AB0139211A1P1 is secured via standard 22mm spring bars. Use a bifurcated spring bar tool to compress the ends of each bar, releasing the strap from the lugs without marking the case. The procedure takes under two minutes and can be performed independently with the correct tool.

Yes. Any strap with a 22mm attachment is compatible with the Navitimer AB0139211A1P1.

The 22mm lug width is one of the most widely supported sizes in the quality aftermarket segment.

Longevity depends on the leather, care routine and frequency of wear. A quality vegetable-tanned calfskin strap, conditioned every two to three months and kept away from prolonged exposure to moisture and perspiration, typically lasts two to four years. Alligator and shell cordovan, with their denser fibre structure, often reach four to six years. Milano Straps straps carry an 18-month manufacturing defect guarantee.
