FAQ
What is the lug width of the Oris Aquis 01 643 7654 7185-Set RS?
The lug width of this model is precisely 20 millimetres. It is measured as the internal distance between the two suspension pins that connect the case to the strap. This width is specific to the Aquis model and ensures complete compatibility with artisanal straps available on Milano Straps.
What is the best strap for the Oris Aquis 01 643 7654 7185-Set RS?
The choice depends on your use case. For discreet elegance: alligator with vegetable tanning in dark brown creates a fascinating dialogue with the ceramic bezel. For authentic aquatic use: corrosion-resistant rubber maintains technical performance and resists both fresh and salt water. For versatility: dense cotton NATO strap allows rapid switching without specialist tools.
How do I change the strap on the 01 643 7654 7185-Set RS?
You require minimal tools: a small screwdriver or dedicated strap removal tool. Gently remove the pins securing the strap to the case attachments (two lateral and one central if present). Insert the new strap by aligning its holes with the case attachments, reinsert the pins, and verify the strap sits perfectly horizontal. Do not over-tighten to avoid deforming the titanium.
Can I use an aftermarket strap on this Oris Aquis?
Yes, absolutely. The 01 643 7654 7185-Set RS uses standard universal 20-millimetre attachments. Any artisanal strap with compatible 20mm lugs integrates without modification. On Milano Straps you will find straps in leather (alligator, calf, cordovan), NATO and rubber, all available in this width and customisable.
How long does a leather strap last on a watch like this?
A vegetable-tanned leather strap typically lasts 18-36 months in daily use on a sports watch. Longevity increases if you rotate periodically between two straps, allowing the leather to breathe. On a diving watch like the Aquis with frequent salt water exposure, the leather strap ages more rapidly; we recommend alternating with a rubber strap during summer months or periods of heavy marine use.
