  • Oris’s altitude-measuring watch
    may have been designed for the
    skies, but it breaks new ground.
    The Big Crown ProPilot Altimeter is
    the world’s first watch with both an
    automatic mechanical movement and
    a built-in mechanical altimeter. It can
    also measure air pressure, using the
    miniaturised aneroid wafers hidden
    under the dial. Oris has a patent
    on this world-first instrument.
