Frequently asked questions
What is the lug width of the Oris Aquis 01 733 7770 4158-07 4 18 66FC?
The lug width (also called ansa measurement) of this reference is 18mm. This dimension corresponds to the space between the lugs of the case where the strap is attached. Measuring accurately is straightforward: place a measuring tape between the two metal eyelets and note the internal distance. For the Aquis 36.50mm, the result will always be 18mm.
Which strap is most suitable for the Oris Aquis 36.50mm?
The choice depends on intended use. An alligator leather or vegetable-tanned calf offers formal elegance and develops a rich patina over time. A technical NATO fabric strap maintains the sports spirit and offers quick replacement convenience. A vulcanised rubber strap ensures secure grip in aquatic contexts. All materials must respect the 18mm lug width for perfect compatibility.
How do I change the strap on the Oris Aquis?
The change is made by extracting the spring bars from the case lugs. A dedicated spring bar tool or small screwdriver is required. Maintain downward pressure to free the bar from one lug, then extract the strap. Insert the new strap by aligning the holes with the case axes and re-press the bars until they click into place. If unfamiliar with the procedure, strap change service is available at Casati Milano.
Is there an aftermarket strap compatible with this reference?
Yes, any strap with an 18mm lug width is compatible with the Oris Aquis 01 733 7770 4158-07 4 18 66FC. MilanoStraps offers a dedicated range of artisanal straps in leather, NATO, and rubber, all available in the 18mm measurement. The important factor is confirming that the strap respects the 18mm lug width and that the length is suitable for your wrist.
How long does a leather strap last on this watch?
Durability depends on the tanning method and usage patterns. A vegetable-tanned calf, with appropriate maintenance (protection from excessive moisture), maintains structural integrity for 3-5 years in daily use. An alligator, given the density of the hide, can exceed 5 years. The first sign of wear is thinning at the keeper loops. The patina, conversely, improves with time. MilanoStraps offers strap regeneration services and stitching replacement to extend strap lifespan.
