Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7766 4734-Set?

The lug width is 22mm, measured as the distance between the inner edges of the horizontal spring bars (lugs) of the case. This is an established standard in quality diver tools, allowing structured straps whilst maintaining aesthetic balance on the 41.5mm case.

Which strap should I choose for the Oris Aquis 01 733 7766 4734-Set?

Several options are recommended: vegetable-tanned leather in cognac or black for daily elegance; alligator in black for refined contrast; vulcanised rubber for intensive diving use; cordura NATO for gestural versatility. Choice depends on primary use context and personal aesthetic preference.

How do I change the strap on my Oris Aquis?

Use a spring bar tool: insert the tip into the lateral slot of the lug, press gently to compress the internal spring, then extract the pin. Repeat on the other side. Position the new strap and reinsert the pins, verifying they click firmly into place. Milan Straps provides step-by-step visual guidance if needed.

Are aftermarket straps compatible with the Oris Aquis 01 733 7766 4734-Set?

Yes, provided they respect the 22mm lug width. Milan Straps guarantees full compatibility of its artisanal 22mm straps with this model. Always verify lug width before purchase by consulting the official Oris technical sheet or Milan Straps guides.

How long does a leather strap last on a diving watch like the Aquis?

A vegetable-tanned leather strap typically lasts 3–5 years with daily use, longer if exposed to water only occasionally. Frequent seawater immersion shortens lifespan to 1–2 years. Vulcanised rubber offers superior marine durability (5–7 years), whilst alligator maintains similar longevity to vegetable-tanned leather.
