Viewed from the back, all Oris watches display their mechanical movement in the case back window – but there’s no need to turn this watch over. In the centre, where the dial should be, is an opening into the fascinating world of mechanics. Hours, minutes, and seconds are displayed from the centre. A red triangle at six o’clock indicates the date. It’s show time for High-Mech.
