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

The Oris Big Crown 01 754 7679 4364-07 5 20 76FC features a 20mm lug width, a specification that determines compatibility with all 20mm watch straps. Measurement is performed with a digital calliper between the internal contact points of the lugs.

For the Big Crown, we recommend shell cordovan or vegetable-tanned calf leather to amplify classical character; canvas NATO for tactical vocation; rubber for technical use. Choice depends on daily context and desired aesthetic interpretation.

Use a spring bar tool, a pointed instrument that compresses the small internal elastic pin of the lug. Position the tool in the access hole, push inward and flip the used strap outward. Repeat on the other side. Casati Milano atelier offers assistance by appointment.

All 20mm straps are compatible. Milanostraps.it offers handcrafted straps in leather, NATO, and rubber certified for 20mm lug width. Stainless steel finishes are recommended for material coherence with the case.

Durability depends on frequency of use, climate, and maintenance. A quality shell cordovan or calf leather strap resists 3–5 years under ordinary conditions. Natural patina and ageing are intrinsic characteristics. Periodic conditioning with specific balms extends material lifespan.
