Winding down

Often with a hand-wound watch, there’s no way of being sure when it will stop. Oris has developed a 120-hour power reserve indicator to sit on the back of Calibre 473, a useful function that clearly shows when the time to rewind its five-day reserve is approaching. High performance made even better.
