Frequently asked questions
What is the lug width of the Oris Aquis 01 733 7770 4155?
The Oris Aquis 01 733 7770 4155 features a <a href="/pages/termine-glossario/misura-ansa">lug width</a> of 19mm. This measurement is taken between the suspension pins and is the standard construction specification for the 37mm Aquis case. To verify compatibility, use a digital calliper and position the tips exactly at the horizontal pins.
What is the best strap for the Oris Aquis 01 733 7770 4155?
The ideal strap depends on intended use. For recreational diving and intensive daily wear, FKM or HNBR rubber provides superior chemical and salt resistance. For understated elegance, Italian leather with <a href="/pages/termine-glossario/concia-vegetale">vegetable tanning</a> develops authentic patina over time. A NATO in cordura is the versatile solution for those prioritising quick-change functionality. <a href="/pages/termine-glossario/alligatore">Alligator</a> leather represents maximum sophistication whilst maintaining minimal thickness.
How do I change the strap on the Oris Aquis 01 733 7770 4155?
The Oris Aquis utilises straight horizontal pins. Secure yourself with a dedicated tool (watchmaker's knife with fine blade or precision screwdriver), support the case with a felt block, and remove the lower right pin by pushing from inside outward. Repeat for the left pin. Extract the old strap and insert the new one, aligning the holes carefully. Reinsert the pins and verify alignment. Never force any metal components.
Can I use an aftermarket 19mm strap on this watch?
Yes, any strap with a <a href="/pages/termine-glossario/misura-ansa">19mm lug width</a> is compatible with the Oris Aquis 01 733 7770 4155. However, verify that the strap thickness does not exceed 2.5mm (the toleranced limit of Oris pins). Italian artisanal straps are constructed within this specification. Avoid straps with rigid, non-adjustable buckles if your wrist is particularly slender.
How long does a calf leather strap last on a dive watch like the Aquis?
A high-quality Italian calf strap, subject to occasional recreational diving and normal daily wear, has a functional lifespan of 3–5 years. If exposed to intensive wetting cycles (chlorinated pools, salt water), durability decreases to 18–24 months. <a href="/pages/termine-glossario/concia-vegetale">Vegetable tanning</a> resists UV degradation superior to synthetic tannins. Regular maintenance (rapid post-immersion drying, annual conditioning) extends useful life to 7 years or beyond.
