Strap for Navitimer Quartz 32 Stainless Steel / MOP / Bracelet

The Breitling Navitimer A77320E61A2A1 has a lug width of 16mm. This measurement, taken internally between the two case lugs using a digital calliper, is essential for selecting any compatible aftermarket or replacement strap.

For a 32mm steel case, a smooth vegetable-tanned calf leather strap is the most versatile choice: it complements the compact profile without overwhelming it and develops a personal patina over time. Fine-scale alligator suits formal occasions, whilst a nylon NATO introduces an aeronautical, sportier aesthetic. A steel deployant clasp improves weight distribution across the case for any material selected.

The strap on the Navitimer A77320E61A2A1 is secured by standard 16mm spring bars. To replace it, use a spring bar tool or a dedicated lug knife: compress the spring bar, slide the strap free from the lug, and fit the new one. No watchmaker is required, though it is advisable to work on a soft surface to avoid scratching the case.

Yes. Any strap with a standard 16mm spring bar fitting is technically compatible with the Navitimer A77320E61A2A1. Milano Straps offers a curated selection of 16mm straps in leather, alligator, shell cordovan and NATO, handcrafted in Italy, with full bespoke customisation available through Casati Milano atelier.

The lifespan of a leather strap depends on the hide, tanning method and daily use. A good-quality vegetable-tanned calf strap, properly maintained, typically lasts 2–4 years. High-grade alligator can exceed 5 years if kept away from prolonged exposure to water and perspiration. Casati Milano straps carry an 18-month warranty against manufacturing defects.
