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

The lug width of this model is 24mm. This is a non-standard measurement that requires millimetre-precision verification. To check correctly, place a digital calliper perpendicular to the inner lug passages: the internal distance between both walls must measure exactly 24mm. A measurement error results in direct strap incompatibility, so measuring twice before ordering is essential.

For the 45mm Navitimer, we recommend alligator or vegetable-tanned calf leather. Alligator in dark brown creates elegant contrast without competing with the slide rule bezel, whilst vegetable-tanned calf mirrors the aviator heritage and develops natural patina over time. For sporting contexts, a structured FKM rubber strap maintains legibility without technical compromise. Avoid NATO straps except on casual occasions: the load of a 45mm case on an undersized textile band strains the lugs unnecessarily.

The strap is changed via spring bars. Position the watch on a soft cushion and use a spring bar tool (fork-shaped instrument) to gently compress the bar toward the case centre, then extract the pin from the lug. Repeat on the opposite side. Insert the new strap by sliding its pins into the lug seats and release the bar carefully. The operation takes less than two minutes if the bars are not corroded. If you prefer professional assistance, the Casati Milano atelier offers complimentary strap changes on in-house purchases.

Yes, any 24mm strap with standard spring bars is compatible. However, official Breitling straps are optimised for the oversized case and aesthetic balance, whilst aftermarket options require verification of total length (approximately 110–120mm lug-to-lug for medium wrists). We recommend artisanal straps with hand-stitched edge stain or folded construction: they maintain quality standards consistent with the watch's value without excessive markup.

A quality alligator strap, worn daily and maintained regularly, maintains structural integrity for 3–5 years. Vegetable-tanned calf typically lasts 2–3 years under the same usage pattern, as vegetable tanning is more sensitive to moisture. Degradation occurs gradually: initially the leather softens and develops patina, later micro-cracks appear in the lug fold. Storing the watch in a box with silica gel during inactive months extends strap lifespan. Casati Milano guarantees 18 months on bespoke personalised straps, covering manufacturing defects.
