Strap for Rectangular Date 30 Stainless Steel / Black - Roman / Bracelet

The lug width (also called strap width) is 21 millimetres. This measurement represents the space between the two horizontal pins that attach the strap to the case. Verification with a calliper is essential, as even minor deviations compromise compatibility and overall aesthetic harmony.

The ideal strap depends on intended use and personal preference. A dark brown alligator strap with fine grain texture emphasises the rectangular geometry and austere case construction. Alternatively, calf leather with vegetable tanning offers a patina that evolves over time. A reinforced canvas NATO strap reflects Oris's instrumental and aeronautical heritage. For dynamic environments, matte vulcanised rubber ensures practicality without aesthetic compromise.

Strap replacement requires a spring bar tool (elastic pin extractor). Position the tool beneath the spring bar, applying gentle downward pressure to release the terminal end. Once extracted, the old strap slides away. To install the new strap, align the lug to the first pin, compress the spring bar with the tool, and guide the strap into position, ensuring the pin clicks fully into place.

Yes, provided the strap has a 21-millimetre lug width. Artisanal aftermarket straps offer significant advantages: complete colour personalisation, premium material selection (alligator, shell cordovan, vegetable-tanned leather), customisable hardware (deployant clasps, reinforced passants), and superior construction longevity compared to OEM straps. Always verify that elastic pins are compatible with the case lugs.

A premium vegetable-tanned calf leather strap lasts 3-5 years with regular maintenance (monthly cleaning, avoiding prolonged humidity, occasional protective balm application). An alligator strap, more resistant to tension and flexing, can last 5-7 years. A reinforced canvas NATO strap exceeds 7 years of daily use. Longevity depends on usage intensity, atmospheric exposure, and preventive maintenance. Vulcanised rubber straps maintain elasticity and water resistance for 10+ years if stored away from direct sunlight.
