Strap for Rectangular Date 25.5 Stainless Steel / Red

The lug width of the Oris Rectangular 01 561 7783 4068-07 5 19 18 is 19mm. This measurement is specific to this model and represents the result of construction proportions specifically engineered for the rectangular case dimensions of 25.50mm. To verify strap compatibility, measure with a digital calliper the distance between the two lugs: it must correspond exactly to 19mm.

For the Rectangular Oris, straps in alligator (dark brown or black) are recommended for formal use, or calf leather with vegetable tanning for daily wear with natural patina development. A versatile and sporty alternative is a NATO strap in cotton or linen. The choice depends on the intended context: alligator intensifies formal character, calf leather offers colour evolution over time, NATO provides casual practicality. All our 19mm straps are available in these variants.

Changing the strap on the Rectangular Oris requires the use of a dedicated tool: a spring bar remover tool. Position the flat end of the remover in the access hole beneath the lug and apply gentle upward pressure to release the internal spring. Once the spring bar is extracted, you can remove the old strap and insert the new one, pressing the spring bar back into position. Avoid sudden impacts: precision beats force. If you are not experienced, consult a professional watchmaker.

Any strap with a 19mm lug width is compatible with the Rectangular Oris 01 561 7783 4068-07 5 19 18, regardless of the manufacturer's brand. Compatibility is determined solely by lug width, not by brand name. We recommend artisanal straps in alligator, calf leather, shell cordovan or NATO manufactured to horological standards: these guarantee superior construction quality and longevity compared to generic industrial products. MilanoStraps offers a specialised collection of customisable 19mm straps.

The lifespan of a leather strap depends on material, thickness, tanning method and frequency of use. A high-quality alligator strap lasts 5-7 years of daily wear; calf leather with vegetable tanning lasts 3-5 years. The natural patina that develops over time is a sign of quality, not deterioration. Prolonged exposure to water, chlorine and sunlight reduces lifespan. A NATO strap in synthetic material lasts 10+ years. Periodic maintenance (gentle cleaning, leather conditioning) significantly extends strap life.
