Strap for Navitimer 1 38 Automatic Stainless Steel / Blue / Croco / Pin

The lug width of the Breitling Navitimer A17325211C1P2 is 20mm. This measurement is taken with a calliper across the inner distance between the two lugs. A standard 20mm strap fitted with conventional spring bars will seat correctly without forcing.

For the Navitimer 38mm, the most fitting options are a Mississippiensis alligator strap for formal wear, a vegetable-tanned calf leather strap that develops a patina over time, and a two-piece NATO nylon strap to reference the model's aeronautical origins. Shell cordovan is the premium choice for those who prioritise longevity and lug shape retention.

Strap replacement requires a spring bar tool inserted into the gap between the lug and the strap end to compress the spring bars. Work on a soft surface to protect the dial and use a flat-tip tool to avoid scratching the polished steel lugs.

Yes, any 20mm strap fitted with standard spring bars is technically compatible. Milanostraps.it offers a curated selection of handcrafted 20mm straps by Casati Milano, with full customisation of leather, stitching and buckle.

Strap longevity depends on leather quality and frequency of wear. A quality calfskin strap typically lasts 18 to 24 months with daily use. Hand-stitched alligator or shell cordovan straps, thanks to their denser fibre structure, can exceed 3 to 4 years while retaining shape and structural integrity, particularly when kept away from prolonged moisture exposure.
