Strap for Rectangular Date Diamonds 25.9 Stainless Steel / Silver / Bracelet

The lug width of the Oris Rectangular 01 561 7621 4961-07 8 16 75 is 16mm. This dimension corresponds to the distance between the internal lugs of the stainless steel rectangular case. It is a specific width required for this model, different from standard straps of 20-22mm. To verify compatibility, insert the strap into the case lugs: it must fit without forcing and remain securely in position.

The best material depends on your intended use. Shell cordovan, with its natural grain and fascinating aging process, pairs perfectly with the minimalist aesthetic of the rectangular case. Natural alligator offers a more formal and sober appearance. Vegetable-tanned calf represents a sustainable and comfortable compromise for daily wear. A NATO fabric strap emphasizes the contemporary character of the Rectangular. Technical rubber is ideal for those seeking practicality and visual contrast with the retro geometry of the case.

To change the strap on the Rectangular 01 561 7621 4961-07 8 16 75, use a dedicated tool (spring bar tool or pin remover). Position the watch so the lug is visible and accessible. Insert the tool's tip into the groove located laterally to the lug, applying gentle pressure to compress the internal spring. Once released, the lug (also called spring bar) will extract smoothly. Insert the new strap in the same manner, ensuring the spring clicks firmly into the case lugs.

Yes, numerous aftermarket straps are available commercially, specifically constructed for the 16mm lug width. Milano Straps offers an exclusive collection of artisanal straps in leather, NATO, and rubber, all compatible with your Oris. Choosing a higher-quality strap than the original not only extends the colour versatility of the watch but also improves comfort and durability over time. Always verify that the width is exactly 16mm before purchase.

A high-quality leather strap, such as those made from shell cordovan or vegetable-tanned calf, lasts 3-5 years with regular daily use. Longevity depends on exposure to moisture, perspiration, and direct sunlight. To maintain it: protect the strap from moisture and standing water, occasionally apply leather-specific creams (avoiding the side in contact with the skin), and alternate with different straps to allow natural evaporation. A dark patina and signs of wear are testimonies to character, not defects. If the strap deteriorates, you can always replace it whilst keeping the same watch.
