Strap for Oris Aquis 01 733 7787 4157

The lug width of the 01 733 7787 4157 is 22 mm. This dimension is measured between the two attachment points on the case (lugs). A digital caliper allows precise verification of the distance. It is essential to respect this measurement to avoid gaps between the strap and the case.

The choice depends on intended use. For formal contexts: alligator or vegetable-tanned calf. For intensive daily or marine use: premium NATO or treated rubber. Alligator develops a rich patina over time; NATO offers practicality and swift changes; rubber resists salt and sunscreen oils.

Obtain a spring bar removal tool. Position the watch face-down, locate the pins on the case sides, apply light pressure with the tool to compress the internal spring and slide the pin outward. Once extracted, the old strap separates. Insert the new strap observing proper pin orientation.

Yes, provided the lug width is exactly 22 mm. Quality aftermarket straps (certified alligator, military NATO, vulcanised rubber) often offer performance and finishing comparable to or superior to original Oris straps, with broader colour ranges and customisation options.

Duration depends on tanning method and usage. An alligator strap with vegetable tanning, worn daily in non-marine contexts, lasts 2–4 years before replacement. Constant exposure to salt water, chlorine, or UV light shortens this window. Regular maintenance (light conditioning with specific oils) extends useful life.
