Strap for Big Crown Pointer Date 40 Stainless Steel / Silver

The lug width is 20mm. This specification is essential when purchasing a compatible strap. You can verify this by measuring the distance between the two lugs on the case, or by consulting the official Oris documentation. Always ensure that any aftermarket strap you select is explicitly certified for 20mm compatibility.

The optimal choice depends on intended use. For formal and business contexts, we recommend alligator leather or vegetable-tanned calf in dark brown, cognac, or black. For versatile daily wear, a cotton-reinforced NATO or rubber strap offers practicality without sacrificing elegance. For those seeking maximum flexibility, a steel deployante clasp on leather enables rapid switching between different solutions.

The Big Crown uses standard spring bars. To remove the strap: place the watch on a soft surface, locate the spring bars on both sides of the case, press them inward with a dedicated spring bar tool, and slide the old strap away. Insert the bars into the new strap's lugs, ensuring the springs click securely into place. If you lack experience, consulting a watchmaker is advisable.

All quality straps with 20mm lug width are compatible. MilanoStraps offers a specialised selection of artisanal leather straps in alligator, calf, shell cordovan, plus NATO and rubber options, all certified for 20mm. We recommend selecting materials that respect the watch's functional heritage: vegetable-tanned leather for evolving patina, natural rubber for lasting resistance, NATO for tactical versatility.

Durability depends on material, tanning method, and frequency of use. A calf or alligator strap with vegetable tanning (as offered by Casati Milano) typically lasts 3-5 years of daily wear, developing a natural patina that enhances appeal. Shell cordovan, due to its density, can exceed 7 years. Exposure to moisture, perspiration, and direct sunlight accelerates deterioration. Regular maintenance—drying and annual conditioning—significantly extends strap lifespan.
