Strap for Navitimer 1 B01 Chronograph 43 Stainless Steel / Airline Editions TWA / Calf / Folding

The lug width of the Breitling Navitimer AB01219A1G1X2 is 20mm. This is the standard measurement to reference when selecting any replacement or aftermarket strap compatible with this reference.

It depends on the intended use. For formal or dress occasions, a 20mm bombé alligator strap paired with a steel deployant clasp suits the technical character of the Navitimer particularly well. For everyday or sport use, vegetable-tanned calfskin or a durable nylon NATO strap offer practical and aesthetically coherent alternatives.

The strap is removed using a flat-tip spring bar tool. The Navitimer's lugs are robust and well-finished: gently lever the spring bar away from the lug to release it, swap the strap, and re-engage the bar on the opposite side. It is advisable to work on a soft surface to avoid scratching the case.

Yes. With a standard 20mm lug width, the Navitimer AB01219A1G1X2 is compatible with a wide range of high-quality aftermarket straps. Milano Straps offers a curated selection of leather, rubber and nylon straps crafted specifically for this attachment standard, including bespoke options via the Casati Milano atelier.

Longevity depends on leather quality and wear conditions. A well-crafted alligator or vegetable-tanned calfskin strap, worn in rotation and kept away from prolonged exposure to water or perspiration, can last between two and five years whilst retaining a presentable appearance. Milano Straps products carry an 18-month warranty against manufacturing defects.
