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

The official lug width is 21mm. This specific dimension constrains the choice of aftermarket straps: every compatible strap must present a 21mm lug width to adhere perfectly to the case terminal attachments without undulation or lateral play. An incorrect measurement compromises both aesthetics and comfort.

For this rectangular model, we recommend full-grain leather straps with vegetable tanning, capable of developing natural patina. Genuine alligator offers fascinating texture and superior durability. For sporting use or humid environments, NATO or FKM rubber maintain aesthetic simplicity without functional compromise. Ideal colours are black, dark brown, and anthracite grey.

The strap is fixed via the case terminal attachments using small pins (spring bars). Obtain an extraction tool, position it under the terminal, apply light inward pressure to release the pin. Remove the old strap and insert the new one by aligning the lug to the terminal holes. The procedure requires precision to avoid scratches.

Yes, any strap with certified 21mm lug width is compatible. Always verify the manufacturer's specification before purchase. We recommend straps specialised for Swiss watches, constructed with precise tolerances and materials respecting Oris case quality standards.

Durability depends on tanning method and usage. Vegetable-tanned leather: 4-6 years in daily use with regular maintenance (cleaning, drying, annual conditioning). Alligator: 6-8 years. Shell cordovan: 7-10 years. In humid environments or with constant sweat exposure, durability reduces. Wear signs include cracks, loss of elasticity, and colour fading.
