FAQ

What is the lug width of the Breitling Navitimer A17395361L1P1?

The Breitling Navitimer A17395361L1P1 has a lug width of 18mm. This measurement, taken between the two lugs with a calliper, determines compatibility with any replacement strap. The buckle end typically tapers to 16mm.

What is the best strap for the Breitling Navitimer 35mm?

For the 35mm steel Navitimer, a vegetable-tanned calf or bespoke alligator strap is the most coherent choice given the case's technical character and proportions. A nylon NATO strap suits daily use, whilst a deployant clasp helps preserve the strap's shape over time.

How do I change the strap on the Breitling Navitimer A17395361L1P1?

Remove the strap using a flat-tip spring bar tool, applying gentle lever pressure between the lug and the spring bar. Work on a soft surface to avoid scratching the case. The 18mm spring bar is then inserted into the new strap and clipped back into the lugs with light, even pressure.

Are there aftermarket straps compatible with the Navitimer A17395361L1P1?

Yes. Any strap with an 18mm attachment width is technically compatible. Milanostraps.it offers a curated selection of handcrafted leather, NATO, and rubber straps sized for this specific lug width, with bespoke options available through the Casati Milano atelier.

How long does a leather strap last on a Breitling Navitimer?

A quality leather strap — vegetable-tanned calf or alligator — with daily use and proper care typically lasts between 18 and 36 months. Minimising exposure to perspiration and moisture significantly extends strap life. The Casati Milano guarantee covers manufacturing defects for 18 months.
