Stepping up in Oris's range
The Divers Sixty-Five has run continuously from the original 1965 model, but this version marks two firsts for the line: it is the first to bring the Calibre 400 outside of a limited run, and the first Sixty-Five fitted with a 12-hour bi-directional bezel — a layout borrowed from military tool watches of the same era, where a second timezone read more naturally than a 24-hour scale. The Calibre 400 is where the real argument is made. Oris developed it in-house with a silicon escapement, resistance well beyond the ISO anti-magnetic standard, and a 120-hour power reserve — then backed it with a ten-year warranty and ten-year service intervals. That last point is the practical one: most automatic movements expect a visit to a watchmaker at roughly half that interval. At 40mm with a 48mm lug span it sits proportionally on a mid-sized wrist, and despite the domed crystal the case wears noticeably slimmer than its stated thickness suggests. The black leather strap with white accent stitching keeps the reference to the sixties legible without being laboured about 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 100m it is rated for swimming and snorkelling, though not for 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 120 hours fully wound — enough to sit off the wrist over a weekend and still be running.
What size strap does it take?
20mm. 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 men's, though at 40mm it sits in the range that suits anyone.
