Oris Aquis 43.5 — strap questions
What strap size does the Aquis 43.5 take?
The Oris Aquis 43.5 doesn't use standard spring-bar lugs — it has an integrated/proprietary fitting, so you need Aquis 43.5-specific straps or an adapter kit rather than a normal strap.
Can I put a normal NATO or leather strap on it?
Not directly. A standard strap won't attach without a model-specific adapter — fit the adapter first, then a normal strap can be used.
Where can I buy straps that fit the Aquis 43.5?
Search for straps and adapters made specifically for the Oris Aquis 43.5; generic sizes won't clip in without one.
