Strap for Oris Aquis 01 733 7789 4154

The Oris Aquis 01 733 7789 4154 features a lug width of 23 millimetres. This measurement refers to the distance between the two spring bars that protrude from the case and accommodate the strap. It is essential to measure this accurately using a digital calliper, excluding any soft components of the original strap, to ensure correct compatibility with aftermarket straps.

The Oris Aquis is a professional dive-watch that pairs excellently with calf leather straps using vegetable tanning, alligator, double-layer NATO, or FKM rubber. Your choice depends on intended use: for frequent marine environments, rubber or NATO is recommended; for formal occasions or cruising, calf or alligator leather. In all cases, the buckle should be crafted from stainless steel or titanium to withstand salt and chlorine exposure.

The strap is changed by removing the two spring bars connecting the strap to the case. Use a dedicated tool (spring bar tool or pin removal tool) to gently extract the pin, taking care not to scratch the case. Once the pin is removed, the old strap slides off easily. Position the new strap, aligning the lug holes, and reinsert the spring bar until it clicks securely. Always verify that the spring bar is fully seated before wearing the watch.

Yes, absolutely. The 01 733 7789 4154 model with 23mm lugs is compatible with any aftermarket strap constructed to this width specification. Milano Straps provides a curated selection of leather, alligator, shell cordovan, NATO, and rubber straps, all certified for precise dimensional tolerances. We recommend verifying strap length (spring bar to buckle) to ensure comfortable fit on your wrist.

Leather strap longevity depends on frequency of use, exposure to moisture, salt, and chlorine, and the quality of tanning. A vegetable-tanned calf strap, used moderately in non-aquatic environments, typically lasts 3–5 years. If regularly exposed to saltwater, durability decreases to 1–2 years. For a dive-watch like the Aquis, we recommend alternating leather straps with rubber or NATO versions during summer months or periods of intense aquatic activity, thereby extending the overall lifespan of all your straps.
