Strap for Navitimer 1461 48 Stainless Steel / Black / Calf / Pin

The lug width of the Breitling Navitimer A1938021/BD20/441X/A20BA.1 is 24mm. This measurement is taken between the two parallel lugs at the point where the strap attaches to the case. Using the correct width is essential to ensure a secure and aesthetically proper fit.

For a 48mm instrument-style case such as this Navitimer, a vegetable-tanned alligator belly strap offers the most balanced pairing: the natural grain complements the layered dial texture, and the leather develops a rich patina over time. Shell cordovan is an excellent alternative for those who prefer a denser, more polished leather. Vulcanised rubber is recommended for sports use or humid environments.

Strap replacement requires a fine-tipped spring bar tool. Insert the tip into the gap between the lug and the strap end, compress the spring bar inward and slide the strap free. Repeat on the opposite side. To fit the new 24mm strap, compress the spring bar on one side, align it with the lug hole and release. It is advisable to work on a soft surface to prevent scratching the stainless steel case.

Yes. Any strap with a 24mm attachment width is technically compatible with this Navitimer, provided the spring bars are of appropriate diameter for Breitling lugs (typically 1.8mm). Milanostraps.it offers a curated selection of handcrafted leather, alligator, shell cordovan and rubber straps in 24mm width, with customisable taper towards the buckle or deployant clasp.

The lifespan of a leather strap depends on leather quality, frequency of wear and exposure to perspiration and moisture. A quality handcrafted alligator or shell cordovan strap, worn in rotation and properly conditioned (leather cream every 2–3 months), will typically last between 3 and 5 years before showing structural wear. Vegetable-tanned leather develops patina without degrading, unlike chrome-tanned hides which tend to delaminate over time.
