Strap for Oris Big Crown 01 754 7798 4069

The lug width of the Oris Big Crown 01 754 7798 4069 is 20mm. This dimension refers to the distance between the two lugs on the case where the strap is attached. You can verify this by measuring with a calliper or ruler the distance between the two holes on the watch case.

Alligator leather with vegetable tanning is the reference choice for the Big Crown. The natural grain texture dialogues perfectly with the sober dial aesthetic and the watch's aviation heritage. Valid alternatives include soft pull-up calf leather for a more relaxed character, or a Ballistic NATO strap for daily use and humid environments. FKM rubber remains the most sporting solution.

Strap replacement requires two tools: a spring bar tool or a blunt-edged knife. Position the watch on a soft surface to avoid scratches. Insert the tool beneath the spring pin, move gently towards the centre to compress it, and slide the pin out of its seat. Once removed, take off the old strap and insert the new one into the same holes, reinserting the pin until it clicks into place. If unsure, consult a specialist watchmaker.

Yes, all straps with a 20mm lug width are compatible with the Oris Big Crown 01 754 7798 4069. Simply verify that the declared strap width is 20mm. Artisanal quality straps in vegetable-tanned leather, pull-up calf, canvas NATO, and FKM rubber offer valid alternatives to OEM straps, often featuring greater colour variety and personalised craftsmanship.

A vegetable-tanned leather strap of good quality has a lifespan of 3–5 years with daily wear, depending on exposure to sunlight, moisture, and perspiration. Vegetable tanning develops patina over time, adding aesthetic character, whilst the leather gradually dries out. Proper maintenance (avoiding prolonged immersion, applying specific conditioner) significantly extends its life. Canvas NATO straps last longer (5–7 years), as does FKM rubber (7–10 years), due to reduced biological degradation.
