Strap for Navitimer 1 38 Automatic Stainless Steel / Black / Croco / Folding

The Breitling Navitimer A17325241B1P2 has a lug width of 20 mm. This measurement should be taken with a vernier calliper positioned between the two lugs at the point where the strap attaches to the case, not across the outer case diameter. Any 20 mm strap with shaped ends is compatible with this reference.

For the steel Navitimer A17325241B1P2 in the 38 mm case size, an alligator leather strap in vegetable-tanned hide with a matte finish provides the most coherent match for the instrument character of the watch. Alternatively, a padded calfskin strap offers a softer fit for daily wear, while a technical nylon NATO or rubber strap suits more active or outdoor settings. The choice of buckle — tang or deployant clasp — further affects wearability and strap longevity.

The strap on the Navitimer A17325241B1P2 is secured by standard 20 mm spring bars. To replace it, use a spring bar tool — either a forked or pointed tip — to compress the spring bar and slide it free from the lug hole. The operation can be carried out carefully at home, or entrusted to a watchmaker or the Casati Milano atelier, where strap fitting is included as part of the bespoke service.

Yes: any aftermarket strap with a 20 mm lug width and standard spring bars is technically compatible with the Navitimer A17325241B1P2. However, given the slightly tapered lug geometry of this model, straps with shaped or curved ends are recommended for a clean fit. Milanostraps.it offers a curated selection of 20 mm straps and the Casati Milano bespoke service for a perfectly anatomical fit.

Longevity depends on the material and conditions of use. A quality calfskin strap worn daily typically lasts 1–2 years. Vegetable-tanned alligator leather, owing to its dense fibre structure, can exceed 3–4 years with minimal maintenance — a leather conditioner applied every 2–3 months and careful avoidance of prolonged water exposure. Shell cordovan is the most durable option, outlasting virtually any other leather. The Casati Milano guarantee covers manufacturing defects for 18 months.
