Strap for Aquis Date 36.5 Stainless Steel / Black - Diamond / Bracelet

The Oris Aquis 01 733 7731 4194-07 8 18 05P features a lug width of 18mm, measured between the horizontal spring bar seats of the case. This dimension is specific to this reference in the 36.50mm size and is incompatible with 16mm or 20mm straps.

For the 01 733 7731 4194-07 8 18 05P, we recommend straps in natural alligator, burgundy shell cordovan, vegetable-tanned calf leather, or FKM rubber if intended for regular diving. Selection depends on intended use and skin undertone. A stainless steel deployante buckle is essential for secure closure.

The strap is replaced by gently extracting the horizontal spring bars from the case seats using a dedicated spring bar tool. The procedure requires uniform pressure to avoid damaging the integrated case attachment. The new 18mm strap must be mounted with spring bars aligned perpendicular to the lugs.

Yes, provided the strap is certified for 18mm lug width and meets correct technical specifications. Milano Straps artisanal straps are tested for complete compatibility with the Oris Aquis 01 733 7731 4194-07 8 18 05P. We always recommend verifying exact measurements prior to purchase.

A high-quality leather strap—alligator, shell cordovan, or calf—lasts approximately 3-5 years under regular wear, developing a desirable patina. Frequent exposure to water and sunlight accelerates ageing; for repeated diving we recommend FKM rubber straps offering durability exceeding 10 years.
