FAQ

What is the lug width of the Breitling Navitimer MB0210B6/BC79/200S/M20DSA.2?

The Breitling Navitimer MB0210B6/BC79/200S/M20DSA.2 features a 22mm lug width. This measurement should be confirmed using a digital calliper positioned between the lugs at the spring bar attachment point, ensuring precise compatibility with any aftermarket strap.

What is the best strap for the Breitling Navitimer 43mm with a 22mm lug width?

For the 43mm Navitimer, the ideal strap depends on intended use. For formal occasions, a wide-grain alligator strap with a steel deployant clasp offers the highest aesthetic coherence. For daily or active wear, a vegetable-tanned calfskin or a robust nylon NATO strap provides the best balance of practicality and durability.

How do you change the strap on a Breitling Navitimer MB0210B6/BC79/200S/M20DSA.2?

Changing the strap on this reference requires a spring bar tool or a dedicated fork-style instrument. Insert the tool into the lug notch, compress the spring bar, and slide the strap free. The operation does not require case opening and can be completed in a few minutes with the correct tools.

Are there aftermarket straps compatible with the Breitling Navitimer MB0210B6/BC79/200S/M20DSA.2?

Yes, any 22mm strap is compatible with this reference. Milano Straps offers a curated selection of 22mm straps in leather, nylon and rubber, handcrafted from selected materials and available both online and as bespoke commissions through the Casati Milano atelier.

How long does a leather strap last on a Breitling Navitimer?

Strap longevity depends on the material and frequency of wear. A quality vegetable-tanned calfskin strap lasts approximately 2–3 years with daily use. Shell cordovan and alligator, owing to their denser fibre structure, can exceed 5 years while retaining form and appearance. Prolonged exposure to water and perspiration is the primary cause of wear; for humid environments, NATO or rubber straps are recommended.
