Strap for Big Crown Pointer Date Calibre 403 Stainless Steel / Red

The lug width is 20 millimetres. This measurement, standard for mid-to-large format horology, allows pairing with straps of considerable thickness without aesthetic compromise. To verify compatibility, measure the distance between the two lugs on the case: if it reads 20mm, you may use any strap constructed to this specification. You have a wide selection available: vegetable-tanned leather, alligator, shell cordovan, cotton NATO, natural and synthetic rubber.

The choice depends on context of use and personal aesthetic preference. For formal professional environments, we recommend vegetable-tanned leather in dark brown or shell cordovan rich with patina: both age magnificently and develop character over time. For elegant everyday wear and sustainability, an alligator strap with vegetable tanning offers fascinating texture and minimal maintenance. Should the watch live in sporting or outdoor contexts, heavyweight cotton NATO or natural rubber guarantee reliability without surrendering the Big Crown's vintage language. The case's satin-finished steel harmonises with any satin deployante clasp.

The Big Crown uses standard spring bar lugs. Equip yourself with a spring bar tool (specialist instrument for sprung lugs): insert the small apex into the lug slot, gently lift to release the pin, and withdraw the strap. Repeat on the other side. To install the new strap, align the hole with the pin, press the strap toward the case body until the lug clicks into position. Apply this procedure to both sides. If you lack experience, consult your retailer: Oris recommends verifying correct installation to avoid damaging either the strap or the lugs.

Absolutely. The Oris Big Crown 01 403 7799 4068-07 6 20 11FC mounts standard 20mm lugs, meaning any strap constructed to this measurement is compatible. Milanostraps.it offers a curated selection of artisanal straps in vegetable-tanned leather, alligator, shell cordovan, NATO and rubber, all available in 20mm. Purchasing a quality aftermarket strap allows you to expand the watch's aesthetics and functionality well beyond original Oris options, personalising your wearing experience.

Longevity depends on tanning quality, thickness, exposure to moisture and frequency of wear. An artisanal vegetable-tanned calf or shell cordovan strap, worn regularly, resists between 3 and 7 years before showing significant wear signs: creasing in the keeper or loss of elasticity. Natural rubber typically lasts 4–6 years. Cotton heavyweight NATO, given its constructive simplicity, can exceed 10 years if properly maintained. To extend service life, avoid prolonged direct sunlight exposure, stagnant humidity and excessive heat. Occasional maintenance with vegetable-leather-specific balm preserves softness and slows ageing.
