Frequently asked questions

What is the exact lug width of the Oris Aquis 01 749 7677 7154-Set?

The lug width of the Oris Aquis 01 749 7677 7154-Set is 20mm. It is measured with a digital calliper inserted perpendicularly between the lugs of the case, measuring the distance between the two inner poles. This dimension is standard in the professional diving watch segment for 43mm cases and ensures visual and functional balance with case proportions.

Which type of strap is most suitable for the Oris Aquis 01 749 7677 7154-Set?

Four main strap types are recommended for the Oris Aquis 01 749 7677 7154-Set: (1) Vegetable-tanned alligator leather for elegance and natural patina evolution over time; (2) Vulcanised rubber with texture for maximum marine functionality and wet grip; (3) Ballistic canvas NATO for tactical versatility and double-pass security; (4) Suede calfskin for aesthetic discretion. Choice depends on intended use and desired stylistic interpretation.

How do I change the strap on the Oris Aquis 01 749 7677 7154-Set?

Strap replacement occurs via the spring bars located on the case lugs. Using a dedicated removal tool, gently compress the spring of the first lug, extract the old strap, then insert the new one by sequentially engaging the lugs in corresponding holes. The procedure requires care to avoid scratching the titanium case; milanostraps.it offers change assistance by appointment at Casati Milano atelier.

Can I use non-original aftermarket straps on my Oris Aquis 01 749 7677 7154-Set?

Yes, the Oris Aquis 01 749 7677 7154-Set is fully compatible with quality aftermarket straps, provided they respect the 20mm lug width. The market offers countless premium leather options, sport rubbers and technical textiles that not only guarantee functionality equivalent to original solutions, but often add personalised aesthetic character and artisanal material excellence.

How long does a leather strap last on the Oris Aquis 01 749 7677 7154-Set?

A superior quality leather strap, if subject to routine maintenance (rapid drying after water contact, avoiding prolonged direct heat, periodic application of natural balm), maintains functionality and aesthetics for 4-6 years under moderate use conditions. Vegetable-tanned leather develops a fascinating aged patina, whilst rubber straps, being synthetic elastomeric materials, have greater durability (8-10 years) but with less aesthetic evolutionary character.
