Stepping up in the same colour and case shape
The Aquis line was designed from the outset as a serious diver that could be worn every day without looking like equipment. The 43.5mm case achieves roughly 12mm in thickness — unusually restrained for a 300-metre-rated watch, and enough to make it disappear under a cuff in a way that few divers its size manage. The case profile widens as it tapers toward the wrist, a deliberate geometry that distributes the weight and keeps the watch sitting flat rather than rocking on the arm. The blue rubber strap is a more practical choice than it might first appear: matched in colour to the dial and ceramic bezel insert, it reads as a considered whole. The Calibre 733 inside is Oris's modification of the Sellita SW200, identifiable by the red automatic rotor visible through the mineral-glass caseback window. It is not a decorated movement, but the rotor is a long-standing Oris signature, and the movement itself is thoroughly proven at this kind of daily-wear pace. New owners may find the bezel requires a few wears before the clicks settle into a consistent action.

Learn more about Oris
Paul Cattin and Georges Christian took over an empty factory in Hölstein in 1904 and named the company after a nearby gorge. It stayed independent, and stayed in that valley, for its entire history.
Oris built its reputation on volume mechanical watches made properly. By the 1960s it was among the largest Swiss employers in the sector, producing hundreds of thousands of movements a year. Its most curious historical footnote is regulatory: Swiss law restricted the number of jewels a watch could contain under certain classifications, and Oris fought a decade-long legal battle to be permitted to fit lever escapements — winning in 1968.
The quartz crisis nearly ended it. The company was bought out of the ASUAG conglomerate in 1982 by two managers, Rolf Portmann and Ulrich Herzog, who took it back to mechanical watches exclusively at precisely the moment the rest of the industry was abandoning them.
That independence remains the point. Oris is one of the few Swiss houses of any scale with no group ownership, and it competes on value rather than prestige — dive watches, pilot's watches, and the Big Crown line descended from its 1938 pointer calendar. The house developed its own Calibre 400 family from 2020, offering five-day power reserves and ten-year service intervals at prices well below the norm for in-house movements.

Frequently asked questions, and things you should know about this watch
Can I swim with it?
Yes. At 300m it is rated for swimming, snorkelling and recreational diving.
Water resistance explainedWill the glass scratch?
Unlikely. Sapphire is second only to diamond in hardness and shrugs off everyday marking.
Sapphire, mineral and acrylic comparedDoes it need a battery?
No. It is automatic — the motion of your wrist winds it, and there is no cell to replace.
Quartz, automatic and solar comparedHow long does it run for when it's not worn?
About 38 hours fully wound — so it will usually stop if you leave it off overnight.
Is it a men's or women's watch?
Listed as men's.
