Frequently asked questions

What is the lug width of the Breitling Navitimer R77320E61A1R1?

The Breitling Navitimer R77320E61A1R1 features a lug width of 16mm. This is the internal measurement between the two case lugs and is specific to the 32mm version of this model. It should not be confused with larger Navitimer variants, which use 22mm or 24mm lug widths.

What is the best strap for the Breitling Navitimer R77320E61A1R1 in red gold?

For a 32mm Red Gold case, the most coherent choice is a belly-cut alligator strap in vegetable-tanned leather, preferably in cognac, bordeaux, or midnight blue. Box-calf leather in a gloss finish is a more understated yet equally refined alternative. Both options complement the precious nature of the case without overpowering it.

How do I change the strap on the Breitling Navitimer R77320E61A1R1?

The strap is removed using a spring bar tool or a dedicated watch strap changing instrument. The 16mm spring bars must be compressed to release them from the lug holes. It is advisable to have this done by a watchmaker or specialist atelier to avoid scratching the red gold case.

Are there aftermarket straps compatible with the Breitling Navitimer R77320E61A1R1?

Yes, there are artisanal aftermarket straps compatible with the 16mm lug width of the Navitimer R77320E61A1R1. Milano Straps offers a curated selection of 16mm straps in various materials and finishes, including bespoke options crafted by Casati Milano atelier. Always verify the exact lug width before purchasing.

How long does a leather strap last on the Breitling Navitimer R77320E61A1R1?

The lifespan of a leather strap depends on the material and daily wear conditions. A quality vegetable-tanned alligator strap, with proper care, can last between 3 and 7 years. Box-calf tends to wear more quickly when exposed to perspiration. Shell cordovan offers the greatest longevity among traditional leathers. Casati Milano provides an 18-month warranty against manufacturing defects.
