Strap for Navitimer 1 35 Automatic Stainless Steel / MOP / Croco / Folding

The lug width of the Breitling Navitimer A17395211A1P4 is 18mm. This measurement refers to the internal distance between the two lugs of the case and determines compatibility with any aftermarket or original replacement strap.

For the Navitimer 35mm, an alligator strap with vegetable tanning is the most balanced choice between elegance and durability. The belly grain complements the visual complexity of the dial. Alternatively, a smooth calf strap in tan or cognac offers a soft feel on the wrist and a refined profile suited to both daily wear and formal occasions.

To replace the strap, remove the spring bars securing the current strap to the case lugs using a dedicated spring bar tool or a flat-bladed watchmaker's screwdriver. The Navitimer 35 uses spring bars of approximately 1.8mm in diameter; it is advisable to replace them alongside the strap to ensure long-term security and integrity.

Yes. Any strap with an 18mm lug width and standard length (typically 115/75mm for the 35mm case) is compatible with the A17395211A1P4 reference. It is important to check that the end-piece curvature matches the lug profile of the Navitimer. At milanostraps.it you will find a curated selection of handcrafted 18mm compatible straps.

The lifespan of a leather strap depends on tanning quality, fibre thickness, and conditions of use. A high-grade vegetable-tanned alligator strap, worn daily and kept away from prolonged moisture, typically lasts 2–4 years. Calf leather offers a similar lifespan. Shell cordovan, owing to its dense fibre structure, can exceed 4 years while developing a distinctive patina over time.
