Strap for Navitimer 1 35 Automatic Stainless Steel / Copper / Bracelet

The Breitling Navitimer A17395201K1A1 has a lug width of 18mm. This measurement should be taken with a digital calliper positioned between the two parallel lug walls at their narrowest point. Adhering precisely to this width is essential to ensure correct strap fitment and reliable retention.

For the 35mm steel Navitimer A17395201K1A1, the most suitable options are a smooth-belly alligator strap for formal wear, a vegetable-tanned calf leather strap for daily use that develops a natural patina over time, and a military-style two-piece NATO nylon strap for a sporting aesthetic consistent with the watch's aviation heritage. The correct width is 18mm, with a pin buckle or deployant clasp in stainless steel.

The strap on the Navitimer A17395201K1A1 is secured by spring bars housed in the perforated lugs, a signature feature of the Navitimer case. A dedicated spring bar tool or fork-tip lever is sufficient to release them. It is advisable to protect the lug flanks with a soft cloth during the operation to avoid scratching the case.

Yes, any strap with an 18mm attachment is technically compatible with the Navitimer A17395201K1A1, provided the spring bars have the correct diameter for Breitling's drilled lugs. Milano Straps offers a curated selection of handcrafted 18mm compatible straps available online, or bespoke options through the Casati Milano atelier.

The lifespan of a leather strap depends on the material and care taken. A quality vegetable-tanned calf leather strap, with daily use and proper maintenance, typically lasts 2 to 3 years. Alligator leather, owing to its scale structure and hide density, can exceed 4 to 5 years. Prolonged exposure to water and perspiration accelerates degradation; it is advisable to rotate straps and avoid contact with salt or chlorinated water.
