Strap for Oris Aquis 01 733 7731 4195

The Oris Aquis 01 733 7731 4195 features an 18-millimetre lug width. This measurement is taken from the inner face of one lug to the other in a straight line through the centre of the case. It is essential to verify that any replacement strap matches this specific width to avoid forcing the lug slots, which could damage the case finishing.

We recommend a vegetable-tanned Tuscan leather strap, which develops a rich patina over time and creates an elegant contrast with the deep blue dial. For a more formal aesthetic, black alligator offers a distinctive geometric texture that complements the case beautifully. For actual water use, vulcanised rubber is the most practical and weather-resistant choice.

Strap replacement is performed by extracting the lug pins (springbars) using a dedicated tool such as a strap removal tool. Place the watch on a soft surface, locate the springbar beneath each lug, compress the moving part with the tool to widen the internal spring, and withdraw the pin. Repeat on the opposite side. Insert the new strap by reversing the procedure, ensuring the pin is fully seated.

Yes, the strap supplied with the 01 733 7731 4195 is fully compatible with any universal 18-millimetre strap. You may use aftermarket straps in leather, rubber, fabric or other materials, provided they conform to the 18 mm lug width specification. Milano Straps offers an extensive range of artisanal straps specifically compatible with this model.

A vegetable-tanned leather strap, with regular use and ordinary maintenance, offers a lifespan of 3 to 5 years before visible wear appears in the flex zone. Premium Italian leather may extend this period. Longevity depends on frequency of use, moisture exposure and ambient humidity. With periodic care and rotation among multiple straps, it is possible to significantly prolong useful life.
