Frequently asked questions

What is the lug width of the Oris Rectangular 01 581 7528 4064-07 5 22 44FC?

The lug width is 22mm. This measurement corresponds to the space between the two lugs on the case and is specifically calibrated for this rectangular case geometry. Ensuring you select straps compatible with this exact 22mm dimension is essential for proper fit and aesthetic harmony.

What is the best strap for the Oris Rectangular 01 581 7528 4064-07?

For this formal, minimalist case, we recommend fine-grained alligator in neutral tones (black, cognac brown) or aged shell cordovan. If versatility appeals to you, a rigid cotton NATO in navy or charcoal offers elegant simplicity. Vulcanised rubber remains ideal for humid environments. Your choice depends on intended use and desired formality level.

How do I change the strap on a watch with 22mm lug width?

Remove the watch and place it on a soft surface. Locate the spring bars (lug pins) at each lug end, typically accessible from the case side. Use a spring bar tool to compress the pin whilst extracting the old strap. Align the new strap's hole with the lug, then release the tool so the pin secures the strap firmly. Confirm the strap is properly fixed before wearing.

Can I use aftermarket straps compatible with this lug size?

Yes, entirely. Bespoke aftermarket straps in 22mm are fully compatible with the Rectangular 01 581 7528 4064-07. Compatibility depends solely on lug width and leather thickness, not watch brand. Milan Straps offers extensive choice in 22mm premium materials—alligator, cordovan, vegetable-tanned leather—allowing you to customise your watch to personal aesthetic and functional preference.

What is the lifespan of a natural leather strap?

A high-quality artisanal leather strap, worn moderately (5-6 days weekly), typically lasts 3-5 years. Longevity depends on material quality (alligator > cordovan > calf), climate exposure, frequency of wear, and maintenance. Vegetable-tanned leather develops patina over time, extending its visual interest. When a strap eventually wears, it can be replaced without compromising the watch—this is the true convenience of standardised lug systems.
