Stepping up in Oris's range
The Aquis was already a capable diver before Oris turned it into a project in 2024. Rather than a full replacement, they ran a careful revision through the collection — reworking the lugs into a more sculpted profile that follows the wrist rather than bridging it, and tapering the crown protectors so they close more neatly around the screw-down crown. The result is a 43.5mm case that reviewers consistently describe as wearing smaller than it measures, the lugs doing the ergonomic work that case diameter alone cannot. The blue sunburst dial shifts noticeably under different light, and the shield-shaped markers give it more character than the flat indices common at this size. That dial pairs with a dark blue ceramic bezel — the same deep tone, brushed and polished — so the whole face reads as a coordinated thing rather than a collection of components. The bracelet carries a micro-adjust system and a clasp with a wetsuit extension, which means the fit you dial in on a Tuesday morning is not the one you are fighting with over a drysuit in January. The Calibre 733 inside is not the in-house 400 series Oris fitted to some 2024 Aquis references, and the 41-hour power reserve reflects that. It is a perfectly solid movement for what this watch is; the caseback has a mineral glass display window if you want to look at it.

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 41 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Is it a men's or women's watch?
Listed as men's.
Cheapest place to buy
Both Mappin & Webb and Goldsmiths list it at £2,200, so choose on delivery and warranty rather than price.
