Strap for Big Crown Pointer Date 36 Stainless Steel / Black

The Oris Big Crown 01 754 7749 4064-07 5 17 65 features a lug width of 17 mm. This dimension is specific to this model and allows the fitment of compatible bespoke straps. To verify compatibility, measure the space between the spring bar pins on your watch case.

The ideal strap depends on intended use and aesthetic preference. Genuine alligator with vegetable tanning represents the formal choice for ceremonial occasions; vegetable-tanned calf offers everyday versatility; NATO fabrics emphasise the aviatory heritage of the Big Crown; vulcanised rubber suits sports activities. All are compatible with the 17 mm lug width.

The operation requires a specialised tool: a spring bar tool or small flat-head screwdriver. Insert the tool into the slot of the lug pin to compress the internal spring, then extract the pin from the case. Repeat on the opposite side. Install the new strap by reversing the procedure, ensuring the pins seat correctly in the lugs.

Any strap with spring bar attachment points measuring 17 mm is compatible with your watch. This includes leather straps (alligator, calf, shell cordovan), fabric NATO bands, rubber straps, and even stainless steel mesh. Compatibility is determined exclusively by lug width, not by watch brand.

Leather strap longevity depends on tanning quality, daily wear patterns and environmental conditions. A vegetable-tanned calf strap lasts an average of 3–5 years with daily use. Alligator, being more durable, may last 5–7 years. Shell cordovan, owing to its construction robustness, exceeds 8 years. Exposure to perspiration, humidity and sunlight accelerates ageing; rotating between multiple straps prolongs service life.
