Strap for Big Crown Complication Stainless Steel - Rose Gold / Black

The Oris Big Crown 01 582 7678 4364-07 8 20 32 features a lug width of 20mm. This dimension is measured between the two attachment pins (spring bars) on the case where the strap connects. It is essential to verify this measurement correctly before ordering an aftermarket strap, using a digital calliper to ensure accuracy.

The choice depends on intended use and aesthetic preference. A brown alligator strap with vegetable tanning creates elegant contrast with the brushed steel case, ideal for classical contexts. For sporting versatility, a NATO strap in cotton-polyester is excellent. Those seeking superior patination development, shell cordovan is recommended. For practical everyday wear, a butadiene rubber strap with canvas texture offers durability and technical functionality.

Strap replacement requires extraction of the attachment pins (spring bars) positioned horizontally at both case lugs. Use a dedicated tool (pin remover or modified toothbrush) to apply gentle pressure beneath the pin, then withdraw the old strap. Position the new strap by aligning the holes with the pins and press firmly until secure. We recommend assistance from an expert on your first attempt.

Yes, theoretically any strap with a 20mm lug width is dimensionally compatible. However, we recommend considering strap thickness and buckle type. An overly thick strap may prove uncomfortable; a deployante buckle provides superior comfort compared to a standard pin buckle. Milano Straps offers artisanal 20mm straps specifically calibrated for the Big Crown's proportions.

Leather strap durability varies based on usage intensity, climate conditions, and leather quality. An alligator or shell cordovan strap with vegetable tanning, worn daily, typically lasts 3-5 years before replacement. Quality calf leather and rubber last 4-6 years. Factors such as sun exposure, humidity, and perspiration accelerate wear. We recommend rotating different straps to extend overall longevity.
