Oris

About Oris

Oris has operated out of Hölstein since 1904 and is one of the last genuinely independent Swiss brands of any scale. It made a deliberate choice to concentrate on mechanical watches when the rest of the industry chased quartz margins, and marks its movements with a red rotor. The in-house Calibre 400, introduced in 2020, offers a five-day power reserve, strong antimagnetism and a ten-year warranty at a price that embarrassed larger houses.

What to look for

Details worth checking before you trust a dial. None of them certify authenticity on their own.

• A red rotor visible through the caseback — Oris' signature since the 1970s
• The Pointer Date's central date hand reading against a chapter ring, not a window
• Calibre 400/401 markings for in-house movements; other models use reworked Sellita bases
• Divers Sixty-Five cases stay deliberately small (36–40mm) with a domed crystal that distorts the dial edge

Facts

• Oris was one of the last brands to hold out against the quartz crisis by continuing to build mechanical watches through the 1970s.
• The Big Crown got its name honestly: the oversized crown was made to be wound by pilots wearing gloves.
