FAQ

What is the lug width of the Oris Rectangular 01 585 7525 4061-07 8 20 68?

The lug width is 20mm. Measure with a digital calliper between the two spring bar lugs of the case. This specific measurement requires dedicated straps, not common production standards.

Which strap is recommended for the Rectangular 01 585 7525 4061-07 8 20 68?

We recommend alligator with vegetable tanning for constructivist sobriety, fine-grained calf for daily elegance, cotton NATO for summer functionality, and isothermic rubber for humid environments. Mixed fabrics are discouraged.

How do I change the strap on the Oris Rectangular 01 585 7525 4061-07 8 20 68?

Use a spring bar tool. Position the case on a soft surface, push downward on the small spring under each lug alternating sides, remove the bar, insert the new strap, reinsert the bar ensuring symmetrical positioning.

Can I use a standard 20mm aftermarket strap on this watch?

Yes, any 20mm strap is mechanically compatible. However, we recommend artisanal products respecting the formal language of the Rectangular. Avoid straps with heavy buckles or excessive ornamentation that would betray constructivist geometry.

How long does a leather strap last on the Rectangular 01 585 7525 4061-07 8 20 68?

A quality vegetable-tanned alligator lasts 3–5 years with regular maintenance (monthly cleaning, quarterly conditioning). Calf leather lasts 2–3 years. Durability depends on sun exposure, humidity, and frequency of use.
