Navitimer A17395211A1P2— lug 18mm

The lug width of the Breitling Navitimer A17395211A1P2 is 18 mm. This measurement should be taken with a digital calliper inserted between the lugs, flush against the case, at the exact point where the strap enters its seat. An imprecise measurement can compromise both the aesthetic fit and the mechanical retention of the strap.

For the 35 mm steel Navitimer A17395211A1P2, the most suitable straps are hornback alligator for formal settings, vegetable-tanned calf leather for everyday wear with natural patina development, and two-tone nylon NATO to reference the original aeronautical aesthetic. In all cases, the strap ends should be pre-curved to conform to the geometry of Breitling's lugs.

To replace the strap on the Navitimer A17395211A1P2, you will need a fine-tipped or forked spring bar tool. Insert the tool into the gap between the lug and the strap, compress the spring bar, and slide it out. Take care not to scratch the steel lugs: it is advisable to protect the area with low-tack masking tape before proceeding.

The lifespan of a leather strap depends on the material and conditions of use. A quality vegetable-tanned calf strap worn daily typically lasts 18 to 24 months before showing signs of structural wear. A well-finished alligator strap can exceed three years. Prolonged exposure to perspiration, water and UV radiation accelerates deterioration: it is advisable to remove the strap in aquatic environments and to apply a conditioner periodically.
