Strap for Big Crown Pointer Date 40 Stainless Steel / Red / Bracelet

The lug width of this model is 20mm. This measurement refers to the distance between the sprung bars on which the strap sits. It is the standard width for this Oris collection and is compatible with a wide range of quality aftermarket straps. To verify, measure the outer distance between the two lugs with a calliper—it should be 20mm.

The ideal strap depends on intended use. An alligator with vegetable tanning in dark brown or black enhances the elegant-civil character of the watch. For a sport-informal aesthetic, a NATO in grey or navy canvas is excellent. For those who frequent water or humid environments, FKM rubber is the most technically robust choice. A thick English calf leather offers a refined middle ground between elegance and constructive solidity.

The process is straightforward: position the watch on a soft surface with the case back facing upward. Using a spring bar tool (precision tool with flat tips), gently push the sprung bar downward. The bar will retract, allowing extraction. Repeat for the other side. To fit the new strap, align the holes with the bars, push the first bar into the hole whilst maintaining position with the tool, and let it snap into place. Repeat for the second bar.

Yes, extensively. Since the lug width is 20mm—a standard size—hundreds of manufacturers offer quality straps. MilanoStraps provides a comprehensive collection of 20mm straps in alligator, calf, shell cordovan, NATO and rubber. All straps are verified for mechanical and aesthetic compatibility with this case.

Durability depends on the tanning method and usage pattern. An alligator with vegetable tanning resists 3-5 years with moderate daily wear. English calf has similar longevity. Shell cordovan, with traditional tanning, can exceed 7-8 years owing to denser fibre structure. Water, direct heat and perspiration reduce lifespan. FKM rubber lasts 5-7 years and is more resistant to mechanical wear.
