Strap for Navitimer Quartz 32 Stainless Steel / MOP / Alligator

The Breitling Navitimer A77320E61A2P2 has a lug width of 16mm. This is a non-standard size within Breitling's general production line, consistent with the 32mm case diameter. It is essential to confirm this measurement before purchasing a replacement strap, ideally using a digital calliper placed between the inner faces of the two lugs.

For the 32mm Navitimer A77320E61A2P2, a vegetable-tanned alligator strap in cognac or tobacco tones represents the most characterful pairing, complementing the visual complexity of the slide rule bezel. Fine-grained or smooth calf leather is well-suited to formal wear, while shell cordovan is the preferred choice for those seeking a strap that develops a distinctive patina over time. For sports or summer use, a vulcanised rubber strap offers comfort and grip without compromising the instrument aesthetic.

Replacing the strap on the Navitimer A77320E61A2P2 requires a flat-tipped springbar tool to release the spring bars securing the strap to the 16mm lugs. The operation is straightforward and does not require a watchmaker: simply apply gentle leverage, taking care not to scratch the stainless steel case surfaces.

Yes, high-quality aftermarket straps compatible with the 16mm lug width of the Navitimer A77320E61A2P2 are available. The selection is more limited compared to standard sizes, but artisan manufacturers such as Casati Milano produce bespoke straps in various materials — alligator, calf leather, shell cordovan — specifically tailored to the 16mm format. The available selection can be browsed on milanostraps.it.

The lifespan of a leather strap on the Navitimer A77320E61A2P2 depends on the material and frequency of wear. A quality vegetable-tanned alligator strap can last between three and five years with regular daily use, developing a characteristic patina. Shell cordovan, owing to its compact fibre structure and resistance to deformation, typically offers greater longevity. Prolonged exposure to water and perspiration should be avoided, and the strap should be stored flat rather than rolled.
