Frequently asked questions
What is the lug width of the Oris Aquis 01 733 7730 4135-07 5 24 10EB?
The lug width of this Aquis model is 24 millimetres, an unconventional specification that requires straps precisely adapted to this attachment width between the two case lugs. Correct measurement is performed by positioning a calliper perpendicular to the case, excluding any decorative or protective elements.
Which strap is recommended for the Oris Aquis 01 733 7730 4135-07 5 24 10EB?
For a technical diver of this calibre, we recommend leather straps in vegetable tanning of high quality in dark tones (cognac brown, black), fluorocarbon rubber straps for maritime use, or NATO straps in embroidered fabric for operational versatility. The choice depends on intended use: professional diving, daily urban wear, or rapid alternation between environments.
How do you change the strap on the Oris Aquis 01 733 7730 4135-07 5 24 10EB?
Use a spring bar tool to remove the spring bars connecting the strap to the case. Position the tool in the small cavity of the spring bar, apply gentle downward pressure, then extract the bar. Proceed symmetrically on both lugs, taking care not to scratch the ceramic and stainless steel case during the operation.
Which aftermarket straps are compatible with 24mm lug width?
Milano Straps offers a selection of artisanal 24mm straps: vegetable tanned and chrome tanned leather, NATO straps in embroidered fabric, silicone and fluorocarbon rubber straps. All models are sized for this specific lug width and ready to ship, with customisation options available online.
How long does a leather strap last on a diving watch like the Aquis?
A high-quality vegetable-tanned leather strap, managed correctly (drying after frequent salt water contact, seasonal rotation), can last 3-5 years with intensive diving use. In urban use, durability extends to 5-7 years. Fluorinated rubber resists salt water indefinitely; deterioration depends on UV exposure. We recommend periodic rotation to preserve your investment.
