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

The Breitling Navitimer U17325211G1U1 has a lug width of 20mm. This measurement should be taken with a digital calliper at the inner base of the lugs, where the case meets the strap. It is the reference dimension required to select any compatible aftermarket strap correctly.

For the bimetallic version in Red Gold and stainless steel, an alligator strap with Hornback grain in matte black or tobacco brown offers the best aesthetic balance. Alternatively, a vegetable-tanned calfskin strap develops a patina over time that suits the Navitimer's instrument-grade character. For a historically coherent look, an aviator brown NATO nylon strap is a well-motivated choice.

The strap is removed using the spring bars housed in the lugs. A forked spring bar tool is recommended to avoid scratching the Red Gold lugs. Given the bimetallic case construction, care is advised during the operation. If in doubt, consult a watchmaker or the Casati Milano atelier for a professional fitting.

Yes. Any strap with a 20mm lug width and a sufficiently flexible backing is compatible with this reference. It is important to ensure the strap's backing is not excessively stiff, as the Navitimer's lug geometry requires some flexibility for proper fit. Milanostraps.it offers a curated selection of compatible 20mm straps, available online and bespoke through the Casati Milano atelier.

The lifespan of a leather strap depends on hide quality, tanning method, and daily use. A high-quality vegetable-tanned alligator strap can last between three and five years under regular wear, provided it is kept away from excessive moisture and perspiration. A well-tanned calfskin strap has a comparable lifespan but develops a visible patina sooner. All Casati Milano straps come with an 18-month manufacturing warranty.
