Strap for Navitimer Quartz 32 Stainless Steel / Blue MOP / Bracelet

The Breitling Navitimer A77320171C1A1 has a lug width of 16mm, measured on the inner side of the case between the two springbar pins. This is a specific dimension of the 32mm version and determines compatibility with any replacement strap.

For the Navitimer A77320171C1A1, the most suitable straps are matte alligator — to complement the satin-finished case — or vegetable-tanned calf leather for everyday use with a developing patina. Shell cordovan is ideal for those seeking a dense, long-lasting surface. In sporty or outdoor contexts, vulcanised rubber preserves the instrument character of the watch. A satin-finish deployant buckle in stainless steel is the most coherent closure choice.

To replace the strap on the Navitimer A77320171C1A1, a spring bar tool with a 16mm fork tip is required. Insert the bifurcated tip between the lug and the strap, compress the spring bar and slide it out laterally. Repeat on the opposite lug. Care should be taken to avoid scratching the stainless steel case; masking tape applied to the bezel is recommended during the procedure.

Yes, any strap with a 16mm attachment is technically compatible with the Navitimer A77320171C1A1. Milano Straps offers a curated selection of handcrafted 16mm straps in alligator, vegetable-tanned calf leather and shell cordovan, with standard lengths (75/115mm or 70/110mm for slimmer wrists) suited to the 32mm case diameter.

The lifespan of a leather strap depends on the material, frequency of wear and maintenance. A vegetable-tanned calf strap typically lasts 2–4 years with daily use; shell cordovan or alligator can exceed 5–7 years when treated with appropriate conditioners and protected from moisture. Milano Straps provides an 18-month warranty against manufacturing defects on all handcrafted straps.
