Frequently asked questions

What is the lug width of the Oris Aquis 01 743 7673 4137-07 8 26 01PEB?

The lug width is 26mm. This dimension is measured internally, from lug to lug of the watch attachment, excluding the spring bars. A 26mm lug width is the standard for large-diameter sport watches such as the Grande Couronne model.

What type of strap is best suited to the Oris Aquis 01 743 7673 4137-07 8 26 01PEB?

It depends on intended use. For elegant versatility, we recommend alligator or vegetable-tanned leather. For swimming and saltwater exposure, an FKM rubber or technical NATO strap offers practicality and durability. For balanced daily wear, a dark blue NATO or cognac-brown leather maintains the sport identity without rigidity.

How do you change the strap on an Oris Aquis?

Remove the old strap by carefully extracting the spring bars with a dedicated tool (spring bar tool). Align the new strap's holes with the watch's spring bars, then insert with controlled pressure until the locking click is heard. The procedure requires no special equipment if executed with care.

Is an aftermarket strap compatible with model 01 743 7673 4137-07 8 26 01PEB?

Yes, provided it is certified for 26mm lug width. Milano Straps artisan straps are manufactured with precise measurements for this width. It is essential to verify compatibility before purchase to avoid aesthetic or functional discrepancies.

What is the lifespan of a natural leather strap on this model?

A quality leather strap, subject to regular maintenance (gentle cleaning and annual conditioning), can last 3–5 years on a daily-worn watch. Frequent water exposure shortens lifespan; it is advisable to dry the leather after prolonged moisture contact. Rubber or NATO straps offer greater longevity in humid environments.
