Strap for Big Crown Pointer Date 40 Stainless Steel - Rose Gold / Silver

The lug width is 20mm, measured as the internal distance between the two lugs that secure the strap to the case. Any aftermarket 20mm strap will fit perfectly this model, provided that the spring bar thickness is between 1.6 and 1.8mm to ensure stability without excessive friction.

An alligator strap with vegetable tanning or chromium-tanned calf leather emphasises visual contrast with the brushed steel case finishing, creating constructive harmony. For casual-sport contexts, a grey-dark nylon NATO strap maintains the avionic aesthetic. In marine environments, a brushed FKM (Viton) rubber strap offers superior grip and zero risk of salt-induced corrosion.

Use a spring bar tool with the correct tip diameter (approximately 1.8mm). Position the tip in the horizontal slot of the pin, apply controlled pressure to compress the spring, then extract the old pin. Insert the new strap by feeding the pin from one side first, align it with the opposite side and press until you feel a distinct click. Verify that the pin is fully seated in both lug holes.

Any 20mm strap with a standard spring bar is compatible. Specialist artisan brands in the 20mm lug width collections guarantee controlled build quality and finishing. Verify that the spring bar thickness is 1.6-1.8mm and that the pins are straight (not angled) to preserve the integrity of the original lug holes.

A chromium-tanned calf or vegetable-tanned alligator strap typically lasts 3-5 years of daily wear, developing predictable patina. Longevity depends on frequency of use, climatic conditions (humidity and heat accelerate wear) and maintenance (regular cleaning and protective treatments prolong lifespan). A NATO or rubber strap has indefinite durability, as these materials do not degrade organically.
