Strap for Aquis Date 43.5 Stainless Steel / Black / Rubber

The Oris Aquis 01 733 7730 4159-07 4 24 64EB features a 24mm lug width. This measurement refers to the distance between the metal spring bars that connect the strap to the case lugs. It is the standard for oversized 43.50mm cases such as the Aquis, ensuring harmonious proportions relative to the case diameter.

The best strap depends on intended use. For vintage diver authenticity: vegetable-tanned leather in burnt brown. For absolute waterproofing: FKM (Viton) rubber. For military versatility: NATO in Cordura. For formal contexts: Nile alligator or vegetable-tanned calfskin. The required lug width is always 24mm.

To change the strap, you will need a spring bar tool (usually supplied with aftermarket straps) and a flat work surface. Position the watch face down, insert the tool tip into the lug hole facing inward, depress the metal pin, and remove the old strap. Repeat on the opposite side. Installation of the new strap follows the reverse procedure.

Yes, provided the strap features a 24mm lug width. This watch uses standard spring bars (removable metal pins with 1.8mm diameter), compatible with the vast majority of artisanal straps on the market. Milano Straps offers a comprehensive collection of 24mm options, from leather to rubber to NATO, all verified for this model.

A quality leather strap (vegetable-tanned) typically lasts 3–5 years with ordinary maintenance: monthly rinsing in fresh water, air drying, annual conditioning with neutral wax. Frequent saltwater exposure accelerates wear. For regular diving use, we recommend rotating 2–3 straps to extend the life of each and permit complete drying between uses.
