Strap for Navitimer 1 38 Automatic Stainless Steel / Red Gold / Silver / Croco / Pin

The Breitling Navitimer U17325211G1P1 features a lug width of 20 mm. Before purchasing an aftermarket strap, it is advisable to verify the exact measurement using a digital calliper directly on the watch lugs, as manufacturing tolerances may vary by a few tenths of a millimetre.

For the red gold and stainless steel bi-metal variant, alligator leather in cognac or warm brown tones is the most aesthetically coherent choice: it enhances the red gold's warm reflections without overwhelming the dial's visual complexity. Shell cordovan is an excellent alternative for everyday wear, owing to its durability and the patina it develops over time. For sport use, a technical nylon NATO strap preserves the watch's aviation identity.

The strap is removed using a flat or forked spring bar tool, applying gentle lever pressure on the spring bars connecting the strap to the lugs. It is advisable to work on a soft surface to protect the bi-metal case from scratches. If in doubt, it is preferable to rely on a watchmaker or the Casati Milano atelier for professional strap replacement.

A quality leather strap — crafted from vegetable-tanned hide and hand-finished — typically lasts 2 to 4 years with regular use, depending on exposure to perspiration, water, and heat. Periodic conditioning with a leather-specific cream significantly extends strap life. Casati Milano provides an 18-month warranty against manufacturing defects.
