Strap for Navitimer Automatic 36 Stainless Steel - Red Gold / MOP / Bracelet

The Breitling Navitimer U17327211A1U1 has a lug width of 18mm. This measurement should be taken with a digital calliper at the internal distance between the two lugs, in direct contact with the case, to ensure accurate fitment of any replacement strap.

For the Navitimer U17327211A1U1 with its mother-of-pearl dial and red gold components, a vegetable-tanned alligator strap in bordeaux or burnt cognac creates a refined chromatic harmony. Shell cordovan in a smooth finish enhances the metallic components. A deployant clasp in red gold or steel completes the pairing with functional coherence.

Strap replacement requires a spring bar tool with a fine tip, inserted into the lateral slot of the lug to compress the spring bar. It is advisable to work on a protective watch cushion to prevent scratches to the case. For first-time replacements or bespoke straps, Casati Milano atelier offers an in-house fitting service.

Yes. The 18mm lug width is a standard size with a wide range of quality aftermarket options available. Milano Straps offers handcrafted straps in alligator, calf leather, shell cordovan and rubber with standard spring bar attachments. It is important to verify the strap thickness at the attachment end, as the Navitimer lug geometry is slightly tapered.

Longevity depends on the leather type and daily use. A quality vegetable-tanned alligator strap, with proper care (conditioning cream every 2–3 months, kept away from direct water exposure), will retain its structural and aesthetic properties for 3–5 years of regular wear. Shell cordovan tends to last longer due to its dense fibre structure. Straps exposed to frequent perspiration benefit from rotation with a second strap.
