Frequently asked questions

What is the lug width of the Oris Rectangular 01 561 7656 4071-07 5 17 70FC?

The lug width is 17 mm. This measurement is critical for selecting a compatible strap: straps of 16 mm or 18 mm width will not provide a secure fit on the lugs. To verify the measurement, use a digital calliper positioned between the two lugs at the point of maximum opening.

What is the best strap for the Oris Rectangular 01 561 7656 4071-07 5 17 70FC?

There is no universal choice. Genuine alligator offers formal elegance and regular grain texture; vegetable-tanned calf leather develops a natural patina over time; NATO fabric maintains visual clarity and versatility of pairing; vulcanised rubber ensures robustness in humid environments. The choice depends on intended use and dial colour.

How do you change the strap on the Oris Rectangular?

Use a spring bar tool to remove the spring bar pins from the lugs. Position the tool near the end of the pin and apply gentle downward pressure until the spring releases. The old strap will then detach. For installation, insert the new strap into the lugs and push the spring bar pins until fully locked.

Are there aftermarket straps available in the 17 mm lug width?

Yes. Milanostraps.it offers a dedicated range of 17 mm straps in alligator leather, vegetable-tanned calf, NATO fabrics and vulcanised rubber. All straps are tested for compatibility and ready to ship, with options for online personalisation.

What is the average lifespan of a leather strap?

A quality leather strap, subject to moderate daily use, maintains structural integrity for 3–5 years. Vegetable tanning evolves with a natural patina that increases aesthetic character. Vulcanised rubber guarantees greater longevity, up to 7–10 years, with minimal maintenance.
