Frequently asked questions

What is the lug width of the Oris Aquis 01 733 7787 4137-07 8 22 04PEB?

The standardised lug width for this model is 22 millimetres. This measurement is proportioned to the 41.50mm case diameter and ensures perfect fit without excess play or tensioning. Measurement is performed by positioning a digital calliper perpendicular to the lug holes, avoiding excessive pressure on the material.

Which strap is most suitable for the Oris Aquis 01 733 7787 4137-07 8 22 04PEB?

For this diving-oriented model, we recommend vegetable-tanned leather for daily elegance, alligator for aquatic and saltwater resistance, or NATO for tactical practicality. Each material expresses a different philosophy of use: leather develops organic patina over time, alligator provides salt and humidity resistance, NATO enables rapid interchangeability.

How do I change the strap on this Oris model?

To change the strap on a watch with 22mm lug width, you will need a spring bar removal tool. Insert the tool's tip into the small groove beneath the case lug, lift gently to compress the internal spring, then extract. Repeat on the opposite side. Insert the new strap by aligning the holes with the spring bar ends and snap into place.

Is an aftermarket 22mm strap completely compatible with the 01 733 7787 4137-07 8 22 04PEB model?

Yes, any quality strap manufactured for 22mm lug width is compatible. However, we recommend verifying that construction tolerances are precise (±0.5mm margin). Milano Straps certifies each 22mm strap for compatibility with cases of this dimension, guaranteeing optimal fit and absence of slipping.

How long does a leather strap last on an Oris Aquis used daily?

A quality vegetable-tanned leather strap, worn daily, typically lasts 3-5 years before requiring replacement due to natural wear. Factors such as humidity exposure, thermal fluctuations and contact with perspiration accelerate ageing. Leather can develop an attractive aesthetic patina in the first 12-18 months of use, where grain becomes evident and colouration deepens.
