Favre-Leuba Raider Bathy 120 Memodepth

For its 50th anniversary, the Raider Bathy 120 MemoDepth comes with an updated depth gauge. A special pressure membrane integrated into the back of the case allows water to enter a chamber where pressure is measured to determine depth up to 120 metres, twice that of the original Bathy watch. Depth is indicated on the dial by the blue centre hand. The watch also has a depth memory function to record the maximum depth reached during a dive. The membrane and movement are hermetically separated, protecting the watch.
