Frequently asked questions

What is the exact lug width of the Oris Aquis 01 400 7763 4117?

The lug width of the Oris Aquis 01 400 7763 4117 is 24 mm. This width is model-specific and determined by the proportion between the case diameter (43.5 mm) and wrist ergonomics. Correct measurement: position a digital calliper on the inner shoulders of the case where the strap connects. Accepts 24 mm straps with maximum tolerance ±0.5 mm.

What is the best strap for the Oris Aquis 01 400 7763 4117?

There is no single «best» strap, but choices suited to specific contexts. For formal use and aesthetic ageing: alligator or calf leather in vegetable tanning. For diving use: FKM (Viton) rubber that guarantees waterproofing and solvent resistance. For balance between aesthetics and functionality: vegetable-tanned Tuscan leather that develops natural patina. Your choice depends on intended use and colour sensitivity.

How do I correctly change the strap on this model?

The Oris Aquis 01 400 7763 4117 uses standard 24 mm lug bars. Procedure: remove the spring bar using the small pass-through hole in the suspension pin (do not force). Extract the old strap. Insert the new strap, aligning inner shoulders to the lugs. Reinsert the spring bar, ensuring it is fully seated on both sides. Verify that the strap does not move laterally. For optimal precision, use a dedicated spring bar tool to protect the case from scratches.

Are aftermarket straps compatible with the Oris Aquis 01 400 7763 4117?

Yes, any 24 mm wide strap is compatible with this model. Note: verify that strap thickness is consistent with the case's lug bars—straps that are too thick may create mechanical stress. Bespoke straps from milanostraps.it are cut to size to guarantee perfect compatibility and structural longevity. The quality of vegetable tanning and leather texture affect final aesthetics more than technical compatibility.

How long does a natural leather strap last on a daily-use watch like the Aquis?

The lifespan of a vegetable-tanned leather strap with daily use ranges from 18 to 36 months, influenced by: frequency of water exposure (sweat, rain, immersion), environmental humidity, and tanning quality. A strap subjected to regular diving use has a shorter lifespan. Recommended maintenance: apply vegetable balm every 4–6 months, allow to dry completely after water exposure (not in direct sunlight). The natural patina that emerges over time indicates aesthetic ageing, not structural deterioration. Replacement is suggested when the strap begins to show visible gaps between shoulder and lug.
