Strap for Navitimer Rattrapante Stainless Steel / Black / Calf / Pin

The lug width (watch strap width) of the Breitling Navitimer AB031021/BF77/439X/A20BA.1 is 24mm. This dimension is the standard for high-end Breitling sports chronographs and is compatible with all 24mm straps available at Milano Straps, both in stock and custom-made versions.

The ideal strap depends on intended use. For classic everyday wear, we recommend dark brown alligator or vegetable-tanned calf in dark brown, offering natural elegance and predictable ageing. For formal contexts, shell cordovan ensures distinctive patina and chromatic stratification over time. For versatility, a steel deployante with leather inserts combines practicality with sophistication.

The Navitimer uses standard lugs with spring bars. Remove the bars using a spring bar tool, extract the old strap and insert the new one keeping the bars in position. This operation requires caution to avoid damaging the lugs. If preferred, Casati Milano offers professional strap change service in the atelier.

Yes, provided it is constructed for 24mm lugs. Milano Straps manufactures artisanal straps in alligator, calf, shell cordovan and other materials certified for compatibility with this reference. The quality of leather and hand-stitching guarantee superior longevity compared to standard industrial straps, with customisation options (length, initials, thread colour).

A quality artisanal strap (alligator, vegetable-tanned calf, shell cordovan) typically lasts 3–5 years of daily wear, extending to 7–10 years with seasonal rotation. Durability depends on: frequency of use, ambient humidity, daily care and tanning quality. Milano Straps straps are guaranteed for 18 months; with proper maintenance (drying after perspiration, annual treatment) they easily exceed construction standards.
