Strap for Rectangular Date Diamonds 25.9 Stainless Steel / Silver

The lug width of the Oris Rectangular 01 561 7621 4961-07 5 16 74 is 16mm. This measurement represents the distance between the two lugs where the strap attaches. Accurate measurement of this dimension is essential to ensure compatibility with any aftermarket strap.

The choice depends on the context of use. For formal elegance: burgundy alligator or shell cordovan. For daily versatility: vegetable-tanned calf in chocolate brown. For sporty occasions: NATO in grey or navy blue. For humid environments: FKM rubber. Each material emphasises different aspects of this Art Deco timepiece's geometric purity.

Position the watch on a soft cushion with the case facing down. Locate the pin that runs through the lug on one side: use a dedicated spring bar tool to gently compress the pin's internal spring and slide it out. Repeat on the other side. Align the new strap's holes with the lug apertures and reinsert the pins. Verify that the strap is securely fastened.

Yes, provided the strap is designed for 16mm lug width. Many high-quality aftermarket straps (such as those available at Milan Straps) offer construction rigour identical to OEM straps, with the possibility of custom personalisation. Always verify the 16mm technical specification before purchase.

A quality leather strap (vegetable-tanned calf, alligator, shell cordovan) typically lasts 3-5 years with daily use, provided appropriate maintenance: avoid prolonged immersion, protect from excessive moisture, apply dedicated conditioners every 6-12 months. Vegetable-tanned leather naturally develops patina, visually extending service life. NATO and FKM rubber have similar durability but less aesthetic character over time.
