The Heritage

The Oris Rectangular 01 561 7656 4074-07 5 17 71FC is a contemporary reinterpretation of Swiss watchmaking's geometric language from the 1940s-50s. The 24.50mm stainless steel satin-finished case maintains a critical balance between visibility and discretion on the wrist, while the Oris 561 manual-wind caliber provides essential functions: hours, minutes, seconds, and date. The 17mm lug width requires specifically sized straps for proper fit without play or excessive tension.

FAQ

What is the lug width of the Oris Rectangular 01 561 7656 4074-07 5 17 71FC?

The lug width of this Oris model is 17mm. This specific dimension reflects the rectangular case geometry and ensures compact proportions. Always verify the measurement before purchasing a compatible strap using a digital calliper or flexible ruler between the two spring bar holes where the strap attaches to the case.

What is the best strap for the Oris Rectangular 01 561 7656 4074-07 5 17 71FC?

The ideal strap depends on intended use. For formal elegance, we recommend deep black or dark brown alligator that emphasises the case geometry. For daily versatility, vegetable-tanned calf leather that develops natural patina. For sportive contexts, cotton-synthetic NATO gabardine. Rubber with fine grain maintains the watch in elegant-discreet territory with maximum practicality.

How do you change the strap on an Oris Rectangular watch?

Strap replacement occurs via the spring bar attachments positioned at the case sides. Use a dedicated tool (spring bar tool) to gently compress the spring and remove it from the previous lug. Insert the new strap by aligning one side first, then compress the spring to secure the second side. Verify both ends are correctly anchored before wearing the watch.

Are aftermarket straps compatible with the Oris Rectangular 01 561 7656 4074-07 5 17 71FC available?

Yes, Milano Straps offers an extensive range of artisanal aftermarket straps in 17mm lug width: alligator, vegetable-tanned calf, shell cordovan, NATO gabardine, and rubber with grain texture. All are crafted to elevated construction standards and ready for dispatch. Compatibility is guaranteed by correct lug width.

What is the average lifespan of a leather strap for the Rectangular Oris?

A premium leather strap (alligator, calf, shell cordovan) maintains aesthetic and functional integrity for 3-5 years with daily wear. Longevity varies according to usage frequency, climate, solar exposure, and maintenance. Vegetable-tanned straps develop desirable patina over time, increasing aesthetic value. Rubber offers superior durability (5-7 years) but gradually loses elasticity. Milano Straps recommends seasonal rotation between materials to extend overall longevity.
