Stepping up in Oris's range
The Divers Date marks sixty years since Oris first built a watch for diving, and it arrives as a genuine reworking rather than a cosmetic refresh. The ceramic bezel insert resists the scratching and fading that plagued earlier anodised aluminium, water resistance doubles to 200 metres, and the lug-to-lug drops from 47.6mm to around 46.5mm — small adjustments that add up to a watch that fits a wider range of wrists than the Sixty-Five it replaces. At 12.1mm thick it is a full millimetre slimmer than its predecessor despite the deeper rating, and at 39mm it sits without drama under a cuff. The warm beige dial is matte and calm, with bevelled applied indices that catch directional light in a way a flat marker never does. Through the mineral-glass exhibition caseback, the red rotor of the Sellita-based Calibre 733 is visible in motion — a detail that rewards the kind of idle attention a watch on the wrist naturally gets. The set includes a Tropic-style rubber strap alongside the steel bracelet, and swapping between them requires no tools, so the watch adapts from desk to water and back without fuss.

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 200m 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 comparedWhat size strap does it take?
19mm. Any strap of that width will fit, and on most modern watches quick-release bars make the swap a two-minute job with no tools.
Is it a men's or women's watch?
Listed as unisex, and at this size it suits any wrist that takes the dimensions.
