Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7653 4137-07 8 26 01PEB?

The lug width of the Oris Aquis 01 733 7653 4137-07 8 26 01PEB is 26mm. This measurement represents the distance between the vertical attachment pins on the case and determines strap compatibility. To verify correctly, position the strap between the lugs and ensure the margin on both sides does not exceed 2-3mm.

What is the best strap for the Oris Aquis 01 733 7653 4137-07 8 26 01PEB?

The ideal strap depends on usage. For office and daily wear, an alligator leather in vegetable tanning measuring 1.4-1.6mm thickness with a stainless steel deployant clasp ensures elegance and practicality. For humid or diving environments, a polyamide NATO or fluoroelastomer is preferable for water resistance. Japanese shell cordovan represents a sophisticated compromise: it resists moisture whilst developing a deep patina over time.

How do I change the strap on a watch like the Oris Aquis 01 733 7653 4137-07 8 26 01PEB?

Remove the old strap using a spring bar removal tool. Position the forked end under the attachment pin, apply gentle pressure to flex the lugs outward, and the pin should slide out easily. To install the new 26mm strap, align the strap holes with the pins and, using the same tool, compress the pins into position until you hear a click. Verify the strap is positioned without inclination.

Can I use aftermarket 26mm straps on this Oris model?

Yes, the Oris Aquis 01 733 7653 4137-07 8 26 01PEB is compatible with any quality 26mm lug width strap. Ensure the strap is specifically dimensioned for 26mm and that the visual width (typically 24-28mm at the centre section) does not exceed the proportions of the 43mm case. Artisanal leather, NATO, and rubber straps from specialist suppliers offer superior aesthetic and functional options compared to generic models.

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

The lifespan of a leather strap depends on material and usage environment. Alligator leather in vegetable tanning subjected to prolonged humidity may degrade in 2-3 years without maintenance; with regular hydration and protection, usable life extends to 5-7 years with continuous aesthetic evolution. Japanese shell cordovan resists moisture better and can last 7-10 years. NATO and fluoroelastomer, being leather-free, maintain structural integrity indefinitely, limited only by mechanical wear or elasticity loss after 10-15 years of intensive use.
