The Oris Aquis 01 400 7763 4157-07 4 24 74EB features a 43.5mm stainless steel case with grey ceramic bezel and is powered by the Oris Caliber 400 mechanical movement.

Water-resistant to 300 metres, the model combines functional diving capability with understated styling characteristic of professional timepieces since the Aquis line's introduction in 1965.

Frequently asked questions

What is the lug width of the Oris Aquis 01 400 7763 4157-07 4 24 74EB?

The lug width is precisely 24.00mm, an uncommon and distinctive dimension in the modern diver landscape. It is measured accurately using a digital calliper, positioning it between the two lugs perpendicular to the bezel whilst excluding the protrusion of the lugs themselves. This width references divers from previous decades and represents a mark of refined engineering discipline.

Which strap would you recommend for this model?

For the Aquis 01 400 7763 4157-07 4 24 74EB, we recommend a vegetable-tanned Tuscan leather in testa di moro tone, which creates elegant contrast with the satin case and grey ceramic bezel. Alternatively, a NATO in khaki or grey offers practical daily wear, whilst a shell cordovan in wine colour emphasises character and individuality. For wet conditions, a black butyl rubber strap with chevron texture ensures grip and marine versatility.

How do I change the strap on the Oris Aquis 01 400 7763 4157-07 4 24 74EB?

The strap is replaced by extracting the spring bars from the lugs. Use a spring bar tool to gently lift one end of the bar, then extract it from one side. Repeat for the other lug. On the new strap, align the holes and insert the spring bars ensuring they are fully seated. Every Milano Straps strap is prepared for 24mm lugs, guaranteeing perfect compatibility.

Can I use an aftermarket strap compatible with 24mm lugs?

Absolutely. The Aquis 01 400 7763 4157-07 4 24 74EB is compatible with any strap featuring 24mm lug width. Milano Straps offers a complete selection of artisanal straps in leather, NATO and rubber, all available for rapid shipment and customisable according to your colour and finish preferences.

What is the average lifespan of a leather strap for this watch?

A strap in vegetable-tanned leather, such as Tuscan, typically lasts 3-5 years under moderate daily use. Longevity depends on humidity exposure, frequency of use and level of care. Applying a water-repellent treatment every 6-8 months will significantly extend the strap's life. NATO and rubber straps offer superior resistance in humid or intense sporting environments.
