Strap for Cockpit B50 Night Mission / Black-Orange / Bracelet

The lug width of the Cockpit B50 VB5010A5/BD41/176V is 24mm. This measurement is specific to this model and represents the result of precise dimensional calculations relative to the 46mm case diameter. It is essential to respect this tolerance when selecting an aftermarket strap.

The best strap depends on use and aesthetic preferences. For formal and professional contexts, we recommend vegetable-tanned alligator or shell cordovan, which develop a natural patina over time. For a more tactical and moisture-resistant approach, FKM rubber or NATO straps in Cordura fabric offer maximum practicality without compromising readability.

The change requires two simple steps: 1) Position the watch on a stable base; 2) Use a spring bar tool to extract the elastic pin that joins the strap to the case. The pin is inserted into the terminal holes of the strap. Professional services are not necessary; the process is reversible and accessible even to those without experience.

Yes, provided it respects the 24mm lug width. Straps in alligator, calf, shell cordovan, rubber or fabric with 24mm lug width are perfectly compatible. It is essential to verify that the strap meets current standards in terms of constructive quality, with robust stitching and precision finishing.

Durability depends on the material and use. An alligator or calf strap well-maintained in vegetable tanning lasts 3-5 years under normal conditions. Shell cordovan, due to its superior density, can last 7-10 years. Exposure to humidity, UV rays and sweat accelerate ageing. A quality bespoke strap such as those by Casati Milano includes an 18-month warranty and can be regenerated through professional reconditioning.
