Strap for Navitimer Automatic 41 Automatic Stainless Steel / Rose Gold / Grey / Bracelet

The lug width of the Breitling Navitimer U17326121M1U1 is 22mm at the case, tapering to a standard 20mm at the strap tip. When sourcing a compatible strap, look for a 22/20mm configuration to ensure a proper fit at both the lugs and the buckle end.

For the rose gold and steel two-tone variant, a glossy alligator strap in cognac or bordeaux provides the most balanced pairing: its regular grain complements the polished case finishing, whilst the warmth of the leather echoes the rose gold tone. Alternatively, a Tuscan vegetable-tanned calfskin strap in natural tan develops a beautiful patina over time and integrates seamlessly with the dial palette.

The strap is secured to the case by standard 22mm spring bars. To replace it, use a spring bar tool to compress each bar laterally and release the strap. Fitting the new strap is the reverse process. The entire operation takes only a few minutes and does not require a visit to an authorised service centre. It is advisable to protect the case with a soft cloth to avoid scratching the lug finishing during the process.

Yes. The Navitimer U17326121M1U1 uses a standard 22mm lug width, making it compatible with a wide range of high-quality aftermarket straps. Milano Straps offers a curated selection of handcrafted 22mm straps in alligator, calfskin, NATO and rubber, available in 22/20mm configurations suited to the Navitimer's lug geometry. Straps can be purchased online or fully customised at the Casati Milano atelier.

The lifespan of a leather strap depends on the hide quality, frequency of use and exposure to perspiration and moisture. A quality alligator strap, with regular use and proper care, typically lasts between three and five years whilst retaining good structural integrity. Vegetable-tanned calfskin, whilst slightly more sensitive to moisture, develops a distinctive patina that enhances its aesthetic appeal over time. Rotating between at least two straps and avoiding prolonged water exposure will significantly extend their service life.
