Strap for Oris Rectangular 01 561 7656 4034

The lug width of the Oris Rectangular 01 561 7656 4034 is 17 millimetres. This non-standard measurement requires pairing with specialised straps. To verify the measurement accurately, insert a digital calliper into the upper attachment holes and measure the internal distance between the two contact points: it must read exactly 17mm to ensure correct fit and secure attachment to the case.

For the Rectangular 01 561 7656 4034, high-quality leather straps are ideal, preferably vegetable-tanned in neutral tones (taupe brown, anthracite grey, black). Shell cordovan represents the most refined solution if available in 17mm lug width, followed by American-cut alligator leather. Alternatively, a cotton-polyester NATO strap in navy blue or sand offers versatility and practicality without formal compromise. A deployant clasp is highly recommended to preserve strap longevity.

Strap replacement is a straightforward mechanical operation requiring a spring bar tool and a clean work surface. Position the watch with the upper lug facing you. Insert the tool into the access hole, apply gentle pressure to compress the internal spring mechanism, and extract the pin with a smooth motion. Repeat for the lower lug. Reverse the procedure to mount the new strap, ensuring the pin is fully inserted and the spring has returned to its original position.

Yes, numerous aftermarket straps are compatible with 17mm lugs, both from generic manufacturers and specialist ateliers such as Casati Milano. Availability is higher than non-standard sizes, though still more limited than widely-distributed dimensions. Consult the milanostraps.it online catalogue to discover leather, NATO and rubber straps ready for dispatch, or request bespoke custom work from Casati Milano.

The lifespan of a leather strap depends on material quality, frequency of use and climatic conditions. A high-quality vegetable-tanned leather strap, paired with a deployant clasp that minimises stress on the shoulder, can last 3 to 5 years under daily-wear conditions. Shell cordovan, if available, offers superior longevity (5-8 years), whilst budget leathers deteriorate more rapidly. Natural leather ageing, featuring patina development and chromatic nuances, represents desirable aesthetic evolution that does not compromise strap functionality.
