Frequently asked questions

What is the lug width of the Breitling Navitimer A17395201K1P2?

The Breitling Navitimer A17395201K1P2 has a lug width of 18mm. This is an atypical measurement for a 35mm case by current market standards, consistent with the historical proportions of the Navitimer collection. To confirm, measure the internal distance between the lugs with a digital calliper after removing the strap.

What is the best strap for the Breitling Navitimer A17395201K1P2?

For the 35mm Navitimer A17395201K1P2, an alligator leather strap in vegetable tanning with an ardillon buckle or steel deployant clasp is the most coherent choice for the watch's formal character. Alternatively, smooth calf leather in cognac or tobacco brown offers everyday versatility. For sporting use, technical nylon NATO or rubber straps are sound options.

How do you change the strap on a Breitling Navitimer A17395201K1P2?

The strap on the Navitimer A17395201K1P2 is secured with standard 18mm springbars. Using a springbar tool, insert the tip into the gap between the lug and the strap, compress the springbar and slide the strap free. The procedure does not require professional watchmaking tools but should be performed carefully to avoid scratching the stainless steel case.

Are there aftermarket straps compatible with the Breitling Navitimer A17395201K1P2?

Yes. Any aftermarket strap with an 18mm lug width is compatible with the Navitimer A17395201K1P2. It is also important to check the standard length (typically 115/75mm or 120/80mm) and to pair it with an ardillon buckle or deployant clasp of 16mm or 18mm. A dedicated selection of 18mm straps is available on milanostraps.it.

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

The lifespan of a leather strap depends on the quality of the tanning, daily use and care. A handcrafted alligator or calf leather strap in vegetable tanning, used in rotation and kept away from excessive perspiration and water, can last between 3 and 6 years whilst retaining its shape. Casati Milano straps carry an 18-month warranty against manufacturing defects.
