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.
