Strap for Navitimer 01 46 Red Gold / Black / Calf / Pin

The lug width is 24mm, corresponding to the distance between the pins that attach the strap to both sides of the case. It is essential to verify this measurement before purchasing an aftermarket strap, as any different width will render the strap incompatible. Milano Straps stocks all 24mm-compatible straps ready for this model.

For red gold and haute horlogerie styling, alligator and shell cordovan represent the ideal choices. Alligator offers intrinsic elegance and develops a natural patina over time. Shell cordovan guarantees superior durability (15+ years) and unique lustre. Vegetable-tanned calf leather is a balanced solution, combining structure, longevity and aesthetic versatility at more accessible price points.

To change the strap, remove the lateral pins securing the current one to the case using a spring bar tool. Press the small metal ring of the pin inward to release the spring tension from its seat. Once the old strap is removed, align the pins of the new strap with the lateral openings and allow the springs to lock them back in place. If unfamiliar with the procedure, the Casati Milano atelier performs the service by appointment.

Yes, provided they respect the 24mm lug width and come from specialised manufacturers. Milano Straps offers handcrafted straps in premium leather and technical rubber, constructed with the same precision as OEM brands. The quality of leather and tanning method (vegetable or chromic) determine longevity. High-end artisanal straps often exceed the durability of industrial alternatives, developing personalised patina over time.

Durability depends on material, tanning method and usage. A high-quality alligator or shell cordovan strap, if properly maintained (avoiding prolonged immersion, drying after moisture exposure), lasts 8-15 years. Calf grain achieves 5-10 years. Factors that shorten lifespan include: prolonged direct sunlight, undried perspiration, persistent humidity. Milano Straps provides straps with 18-month warranty and maintenance guidance.
