Strap for Big Crown Pointer Date 40 Stainless Steel - Bronze / NZZ Edition

The lug width of the Oris Big Crown 01 754 7741 4315-Set is 20mm. This specification is critical for selecting compatible straps. Measure carefully from top to bottom lug, accounting for internal spacing. A tolerance of ±0.5mm is acceptable, though 20mm is the official specification.

Selection depends on intended use. Alligator leather with vegetable tanning complements the bronze case and develops patina over time. Calf leather with vegetable tanning offers formal elegance and durability. NATO straps provide chromatic versatility and sporty robustness. FKM rubber is ideal for aquatic environments or humid conditions. All are available in 20mm width.

Strap replacement requires a springbar tool (lever for removing elastic pins). Insert the flat tip beneath the lug, applying gentle upward pressure to compress the spring, then extract the pin. Repeat on the opposite side. Align the new 20mm strap with the lugs and reinsert pins until you hear a click confirming closure. If uncertain, consult a specialist.

Absolutely. The 20mm lug width is standard, ensuring compatibility with any third-party strap of identical width. Artisan straps crafted from premium materials—alligator, vegetable-tanned calf, pull-up leather—fit perfectly and often enhance wearing comfort compared to original factory straps.

A quality leather strap with vegetable tanning resists 2-4 years under moderate daily wear. Factors affecting longevity include frequency of use, direct sun exposure, environmental humidity, and personal perspiration. Alligator straps reveal elegant, progressive wear and often exceed 5 years. NATO and rubber straps offer lifespan of 5-7+ years owing to material resilience.
