Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7730 4134-07 4 24 64EB?

The lug width of this model is 24mm, which is the distance between the case lugs where the strap attaches. Always verify this measurement before purchasing an aftermarket strap by measuring the width of the integrated lugs with a digital calliper.

Which strap is most suitable for the Oris Aquis 01 733 7730 4134-07 4 24 64EB?

This depends on usage and aesthetic preference. Black alligator emphasises the professional diving nature; vegetable-tanned calf creates a more measured dialogue; a navy or black NATO directly reflects technical vocation. Rubber performs excellently in extreme aquatic environments.

How do I change the strap on this Oris Aquis?

Unscrew the spring bar (present on both sides of the case) using a dedicated tool or precision flat-head screwdriver. Carefully extract the metal lug, free the previous strap, and insert the new one, ensuring the attachment is perfectly centred before closing the spring bar.

Can I fit an artisanal aftermarket strap on this model?

Yes, provided it is manufactured with 24mm lugs. Milano Straps artisanal straps are compatible with this case and often offer construction quality superior to original straps, with customisation options in material (alligator, calf, shell cordovan), colour and texture.

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

A vegetable-tanned leather strap, if subjected to moderate wear and regular maintenance (drying after saltwater contact, annual conditioning with natural waxes), can last 3-5 years. High-quality alligator and calf age nobly, acquiring distinctive patina over time.
