  • Oris’s Big Crown ProPilot Worldtimer
    is a quiet masterpiece. It shows two
    time zones simultaneously, with
    local time – the central hands –
    adjusted in one-hour jumps, forwards
    or backwards, simply by rotating the
    bezel. No fiddling with the crown. No
    additional pushers. Just turn the bezel.
    The date takes in changes forwards
    and backwards over midnight, too. If
    only everything in life was this simple.
