Strap for Big Crown Complication Stainless Steel / Silver / Bracelet

The lug width of this model is 20mm, measured from inside to inside of the spring bar. This dimension accommodates a wide range of artisanal straps, from vegetable-tanned leather to specialty materials such as shell cordovan and alligator, maintaining harmonious proportions with the 40mm case.

For the Big Crown Oris, we recommend vegetable-tanned leather in cognac brown or black for formal elegance, or bordeaux shell cordovan for fascinating ageing. If you prefer functionality, a navy canvas NATO or vulcanised rubber strap offers reliability without compromise. Your choice depends on lifestyle and frequency of wear.

To change the strap, use a spring bar tool (small lever-like instrument). Position the tip in the lug slot, apply gentle downward pressure to retract the internal spring, and slide out the old strap. Reverse the procedure with the new strap, ensuring the spring ends align perfectly in the case holes. Avoid excessive pressure to prevent damage to the metal pins.

Absolutely. The 20mm lug width is an industry standard, so any strap with a 20mm width will be compatible. Milano Straps offers a selection of Italian artisanal straps in vegetable-tanned leather, alligator, shell cordovan, NATO and rubber, all tested for construction quality and durability. Compatibility is guaranteed by a simple lug width verification.

Durability depends on material and usage. A quality vegetable-tanned leather strap lasts 3-5 years with daily wear, developing natural patina that becomes more beautiful over time. Shell cordovan, thanks to its dense fibrous composition, can last 7-10 years. To extend lifespan, avoid prolonged water immersion, protect from excessive perspiration, and occasionally apply leather balm. A canvas NATO, being synthetic, lasts indefinitely but may fray with extended use.
