Strap for Oris Aquis 01 733 7730 4159

The lug width of the 01 733 7730 4159 is 24 millimetres. This measurement must be taken perpendicular to the lugs, from the inside of one lug to the other, using a ruler or calliper. Verifying this dimension before purchasing an aftermarket strap is essential, as even minor discrepancies compromise correct seating on the spring bars.

For this tool watch, we recommend vegetable-tanned Tuscan leather for mixed use (daily and occasional diving), or fluoroelastomer rubber for frequent submersion. Leather develops organic patina over time, whilst rubber offers superior hydrophobic and thermal performance. Ballistic nylon NATO straps are lightweight alternatives for periodic wear.

Obtain a spring bar removal tool and position its tip inside the notch of the spring bar end. Press gently inward until the spring releases, then withdraw the bar and repeat on the opposite lug. Align the new strap ends with the lug holes, then reinsert the bars, applying pressure until an audible click signals secure seating.

A vegetable-tanned Tuscan leather strap, on a diving watch such as the Aquis, has an estimated lifespan of 18–36 months with mixed daily and occasional marine use. Frequent exposure to saltwater and thermal cycling accelerates leather ageing. Regular maintenance (fresh-water rinsing, thorough drying) and periodic rotation with secondary straps significantly extends useful life.
