Stepping up in Oris's range
The ProPilot X has always been the harder-edged side of Oris's pilot line, and the Miss Piggy Edition carries that character into new territory in two directions at once: a 34mm case, the smallest the series has reached, and the first time it has been built in stainless steel rather than titanium. It follows the Kermit Edition of 2023, which found an audience well beyond the brand's usual orbit, and the approach here is a little more restrained than that watch — there is no date window, no portrait on the dial. Miss Piggy is kept in reserve for whoever turns the watch over, where a mineral glass spyhole in the screwed caseback frames a glamorous portrait on the lilac rotor, appearing and disappearing as the movement winds. The fanned bezel, sharp lug angles and crown guards mean that at 34mm this does not read as a delicate watch — the industrial architecture of the ProPilot X survives the size reduction intact. The pink dial works harder than it might seem: the applied hour markers are raised, the sword hands are silver-toned, and a baguette-cut lab-grown diamond sits at 12 o'clock. The mix of brushed and polished surfaces on the bracelet, with its aircraft seat-belt clasp, shifts noticeably as the wrist moves. One concession worth noting: there is no lume on the markers or hands, which is an unusual absence on a pilot's watch rated to 100m.

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.

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 42 hours fully wound — enough to survive a night off the wrist, but not a full weekend.
Will it fit my wrist?
Lug-to-lug is 41.5mm, which suits wrists from roughly 15cm (6 inches) upward.
Lug-to-lug decides fit more than case diameter does.
