Frequently asked questions

What is the lug width of the Oris Williams 01 774 7717 4184-Set RS?

The lug width is 24mm, a standard international specification for modern sport chronographs. This width is determined by the geometry of the case lugs: always measure the distance between the metal shoulders where the strap sits, excluding the spring bars, to ensure correct compatibility with aftermarket straps.

Which strap is best suited for the Oris Williams 01 774 7717 4184-Set RS?

It depends on your intended use and aesthetic preference. Alligator leather in black or dark brown maintains the elegant-sportive character; vegetable-tanned calf develops natural patina over time; FKM rubber is ideal for water activities; NATO in blue (Williams team colours) adds brand storytelling.

How do I change the strap on my Oris Williams 01 774 7717 4184-Set RS?

Use a spring bar tool to depressurise the elastic rings that connect the strap to the case. Insert the tool's tip into the small hole in the upper lug, gently push downward, and extract the spring bar from the lug end. Reverse the process with your new strap, ensuring the rings are fully seated in the case lugs.

Can I use an aftermarket strap on this model?

Yes, absolutely. Any strap with a 24mm lug width is compatible. Milano Straps offers solutions in alligator leather, calf, NATO, and FKM rubber, all pre-verified for Williams dimensions. Avoid straps with overly rigid deployante clasps that could stress the case lugs.

How long does a leather strap last with daily wear?

A quality alligator or calf leather strap lasts between 18 and 36 months of daily use, depending on wear frequency, sun exposure, and humidity. Vegetable-tanned leather tends to age more aesthetically, developing natural patina; FKM rubber can last 5-7 years without significant degradation.
