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

The Oris Big Crown 01 754 7679 4061-07 8 20 30 features a lug width of 20 millimetres. This dimension is proportionate to the 40mm case diameter and ensures compatibility with the entire range of standard 20mm straps available at milanostraps.it. Lug width is measured from the head of the spring bar to the inner shoulder of the lug.

For the Big Crown, we recommend vegetable-tanned calf leather in brown tones or natural alligator with medium grain. These materials respect the functional austerity of the watch whilst amplifying its instrumental identity. For a contemporary approach, a black NATO on grey is equally authentic. FKM rubber is ideal for sustained sport and aquatic use. Avoid overly ornate textures or metallic colours that would compete with the stainless steel case.

Strap replacement requires a dedicated spring bar tool. Position the watch with the lug facing upward, gently compress the spring bar from its base using the extractor, remove the old strap, and insert the new one until you hear the locking click. If uncertain, our experts at Casati Milano offer strap change service by appointment at the Milan atelier.

Yes, provided it is constructed for 20mm lug width. Milanostraps.it supplies only straps measured and tested for this dimension. Every strap in our 20mm collection is calibrated with digital precision before dispatch. Always verify the lug width of your Oris model against the technical documentation before purchase.

A vegetable-tanned calf strap, with ordinary care, has an average lifespan of 5-8 years. Longevity depends on usage frequency, humidity exposure, and maintenance. Casati Milano calf straps in Barenia leather develop a golden patina that documents elapsed time. At end of life, the strap can be replaced whilst preserving the original spring bars.
