Strap for Aquis GMT Carysfort Reef Gold Limited Edition

The lug width of the Oris Aquis 01 798 7754 6185-Set is precisely 26 mm. This dimension is determined by the 43.50 mm case diameter and ensures proper proportion between the lugs and the strap. To verify this measurement, use a calliper or ruler positioned from the inside of one lug to the inside of the other, passing over the dial. Tolerance must be exact: 25 mm would cause excessive tension on the spring bars, whilst 27 mm would introduce unacceptable horizontal play.

For a yellow gold Oris Aquis, we recommend an alligator strap with vegetable tanning, which creates a fascinating dialogue with the natural patina of the metal. Shell cordovan represents a more formal alternative, with inherent lustre that amplifies the luminosity of the case. For sport and diving use, a premium rubber strap with fine grain texture maintains subaquatic functionality without diminishing elegance. Each option must respect the 26 mm lug width to ensure proper fit and security.

Changing the strap on an Oris Aquis requires a spring bar remover tool or a small flat blade. Position the tool between the lug and the strap, apply gentle inward pressure to compress the spring bar, then remove the strap. The procedure is identical for installing a new strap: ensure that the spring bars are fully seated in the holes of the new strap and that the lug width is precisely 26 mm. If you are uncertain, consult a trusted watchmaker.

Yes, aftermarket straps are fully compatible with the Oris calibre 798, since compatibility is determined by lug width (26 mm), not by the internal movement. Any strap in leather, rubber or textile with 26 mm lug width will function correctly. However, we recommend purchasing only from reputable suppliers that guarantee quality spring bars and precise tolerances to prevent lug damage over time.

The lifespan of a leather strap depends on material quality, frequency of use and water exposure. A high-quality artisanal alligator or shell cordovan strap typically lasts 3–5 years with regular daily wear, whilst standard calf leather may last 2–3 years. Saltwater exposure accelerates deterioration: if you frequently use your Oris Aquis for diving, consider a rubber strap during that season. Regular maintenance with specialist creams and drying after prolonged moisture exposure significantly extend longevity.
