Strap for Big Crown Wings of Hope Yellow Gold

The lug width (ansa measurement) of the Oris Big Crown 01 401 7782 6081-Set is 19mm. This measurement represents the distance between the two lugs that hold the strap inside the case. A compatible strap must have exactly 19mm width to ensure correct and stable installation. To verify this with precision, use a digital calliper to measure the interior space between the lugs: the result must correspond exactly to 19mm.

The best strap depends on your usage and personal taste. For formal elegance, we recommend a genuine alligator strap with vegetable tanning, in cognac or dark brown tones, which emphasises the warmth of the yellow gold. For daily sporting use, a robust calf strap or NATO strap in woven fabric offers greater versatility. For dynamic or aquatic use, high-density FKM rubber guarantees waterproofing and zero maintenance. All these straps are available in the 19mm size compatible with this model.

Changing the strap is a straightforward operation: obtain a spring bar tool, available from most strap retailers. Position the watch with the case facing downwards. Insert the forked end of the tool under the lug pin that supports the strap, applying gentle upward pressure until the pin comes free from its seat. Repeat the operation on the opposite side. Remove the old strap and insert the new one, ensuring that the pins align correctly within the lugs (19mm). Verify that the strap is stable before wearing the watch.

Yes, absolutely. The Oris Big Crown 01 401 7782 6081-Set is fully compatible with any quality aftermarket strap manufactured in 19mm size. Bespoke artisanal straps often offer superior construction quality compared to OEM straps, allowing you to personalise your watch and maintain a spare strap for increased overall durability. Ensure that the strap has the correct lug width (19mm) and moderate thickness (0.8–1.2mm) to guarantee smooth insertion within the case lugs.

The durability of a leather strap depends on the type of tanning and the intensity of use. A calf strap made with vegetable tanning can last 3–5 years of regular daily use before requiring replacement. Vegetable tanning tends to crack gradually with continuous movement and humidity exposure. An alligator strap, thanks to its more robust fibre, can extend durability to 5–7 years. Store the strap in a dry place, avoid prolonged direct sunlight exposure, and clean it periodically with a damp cloth. If the strap begins to show signs of structural failure, it is time to replace it to prevent accidental loss of your watch.
