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

The Oris Big Crown 01 754 7679 4364-07 8 20 32 features a 20mm lug width. This measurement is the distance between the case lugs and is essential for selecting a compatible strap. To verify that your new strap fits perfectly into the case lugs, measure the perpendicular distance between the lateral pins with a digital calliper.

The best strap depends on intended usage. For daily elegance, we recommend alligator or shell cordovan with vegetable tanning in cognac or aged brown tones. For versatility, a smooth or grained calf leather in black or anthracite is ideal. For sport activities and diving, a natural or synthetic rubber strap preserves water resistance and provides grip on wet wrists. A NATO strap in heavyweight cotton in grey or navy blue combines functionality with casual aesthetics.

To change the strap, you need to remove the spring bars that anchor the current strap to the lateral lugs of the case. Use a spring bar tool to press downward and release the pin from one side, then extract it completely. Repeat on the opposite side. Insert the new spring bars into the holes of the new strap, then secure the strap to both sides of the case by pressing the bars until they click into place within the lug sockets.

Yes, any strap with a 20mm lug width is compatible with the Oris Big Crown 01 754 7679 4364-07 8 20 32. Artisanal leather, NATO, rubber, and speciality straps (alligator, shell cordovan with vegetable tanning) offer complete aesthetic customisation. Ensure that the chosen strap is made for 20mm lug width and that the visible width is proportional to the 40mm case diameter.

The lifespan of a leather strap depends on the quality of the tanning and usage patterns. A good-quality calf strap lasts 3–5 years with daily wear. Noble materials such as alligator or shell cordovan with vegetable tanning can last 7–10 years thanks to natural resistance and the ability to develop a patina that protects the surface. Frequent exposure to water, humidity and perspiration shortens strap life; regular maintenance (gentle cleaning, occasional conditioning) significantly extends durability.
