Frequently asked questions

What is the exact lug width of the Oris Aquis 01 733 7789 4187?

The lug width of the Oris Aquis 01 733 7789 4187 is precisely 23 millimetres, measured from inner pin to inner pin. This non-standard dimension requires verification of aftermarket strap compatibility before purchase.

Which strap is best suited to the Oris Aquis 01 733 7789 4187?

For technical and aesthetic value, we recommend alligator with natural grain (formal elegance), vegetable-tanned calf (patina development), or vulcanised rubber (pure performance). Selection depends on primary use: diving, formal wear, or mixed purposes.

How do I change the strap on the Oris Aquis 01 733 7789 4187?

Position the watch in a proper holder. Use a precision tool or strap changer to gently compress the lateral pins inward, sliding them horizontally from the lugs. Avoid force to prevent damage. Install the new 23mm strap by reversing this procedure.

Can the original Oris 23mm strap be replaced with a quality aftermarket alternative?

Yes, provided it is verified as 23mm compatible. A quality artisanal strap with a deployant clasp or specific keeper guarantees durability comparable to the original, often with enhanced aesthetic customisation. Milano Straps offers curated selections for this measurement.

What is the typical lifespan of a leather strap on the Oris Aquis 01 733 7789 4187?

With ordinary care (protection from continuous humid environments), an alligator or calf strap lasts 3–5 years of regular use. If frequently exposed to salt water, lifespan reduces to 1–2 years. Vulcanised rubber and synthetic NATO require minimal maintenance but have shorter wear cycles (12–24 months).
