Calibre 473

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.

Anti-magnetism

Swiss watches can be magnetised, affecting accuracy. Oris' Calibre 400 Series uses over 30 non-ferrous, anti-magnetic components for high anti-magnetism. Laboratoire Dubois tests showed Calibre 473 deviated under 10 seconds a day after 2,250 gauss exposure.

10-year warranty

Oris offers a 10-year warranty on Calibre 400 Series watches, reflecting their confidence in the technology. Registration at MyOris is required for warranty extension. Oris also recommends 10-year service intervals for these watches.
