Stepping up in the same colour and case shape
A 40mm solid bronze case with a fluted bezel and a characteristically oversized screw-in bronze crown gives this pilot-inspired watch its distinctive silhouette, sitting 12mm thick with a 47.5mm lug-to-lug span. The matte blue dial carries cathedral hands and a red crescent-tipped pointer that tracks the date around the dial's periphery rather than through a conventional window. Domed sapphire crystal with anti-reflective coating on both sides sits above, while Super-LumiNova on the hands, numerals, and indices ensures legibility in low light. The Oris 754 movement, built on a Sellita SW 200-1 base with 26 jewels and a 38-hour power reserve, runs at 4Hz and includes a stop-seconds function. A multi-piece articulated solid bronze bracelet with folding clasp completes the watch, matched in tone to the case.

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?
Showering yes, swimming no. 50m covers splashes and brief immersion, but a swimming stroke generates well above the pressure that figure describes.
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.
Will it fit my wrist?
Lug-to-lug is 47.5mm, which suits wrists from roughly 16.5cm (6½ inches) upward.
Lug-to-lug decides fit more than case diameter does.
How to size a watch to your wristIs it a men's or women's watch?
Listed as men's, though at 40mm it sits in the range that suits anyone.
