Strap for Big Crown Small Second Pointer Day Stainless Steel / Black

The lug width is 22mm. This measurement determines compatibility with replacement straps: it represents the distance between the two spring bar attachment holes. To verify accurately, position a digital callipers perpendicular to the inner hole diameter of the case, excluding the spring bar itself.

This depends on intended use and aesthetic preference. For formal elegance, vegetable-tanned leather (sand, cognac) or alligator are recommended. For a sports-avionic aesthetic, a NATO strap in grey or navy canvas highlights the Big Crown's historical aviator roots. In humid or high-wear environments, FKM rubber in black offers case protection and simplified maintenance.

Unscrew the spring bar pin on each side using a spring bar removal tool or micro electric drill. Some straps require a nylon hammer and Teflon scalpel for proper removal. If uncertain, seek professional assistance from a qualified watchmaker: excessive force can damage the stainless steel attachment holes.

Yes, any strap with a 22mm lug width will attach mechanically to the Big Crown. However, verify overall length: for a robust 44mm case, minimum 75mm from the lug to strap beginning (short side) and 120-125mm toward the buckle (long side) ensures comfortable wrist fit without excessive folding.

A quality Tuscan vegetable-tanned leather, with regular maintenance (damp cloth cleaning every 1-2 months, conditioning with wax every 4-6 months), maintains dignified appearance for 2-4 years of daily wear. Longevity depends on sun exposure, humidity, and perspiration. On a robust 44mm Big Crown subjected to continuous tension, replacing the strap every 18-30 months is realistic for intensive daily use.
