17 My Casio dive watch flooded.
It was rated to 50M and I was only at 15M. What gives?
The Casio dive watches are supposedly rated in static pressure, not
dynamic pressure. The act of swimming, moving your wrist, bumping the
watch, using the controls, etc., causes large amounts of dynamic
pressure, which can flood your watch.
Casio used to rate their watches by activity. 100M watches were rated
for snorkeling, and only 200M watches were rated for scuba diving. 50M
watches were for showering.
Net experience seems to indicate that your 50M watch is quite likely
to flood if you use it for diving, your 100M watch is somewhat likely
to flood, although some people have used 100M watches for diving
successfully, and your 200M watch is probably not going to flood. A
few people have used 50M watches for diving, but pushing the buttons
at depth, accidentally or on purpose, may flood the watch.
Given that a Casio G-Shock is only about $50 at a discount store, and
that a regular 200M Casio is likely to be around $40, many people seem
to think that skimping further than that (since that is about the cost
of a dive) is false economy, since, if your watch was your only timing
device, you'd have to abort if it flooded.
There are people who believe that this means that some watches are
rated in "marketing meters" and others are rated in "real meters".
Regardless of that, 200M Casios seem to work for scuba and others are
marginal.
If you are interested in information on the Citizen Hyper Aqualand,
and you are not happy with the software you got with your watch, you
might try the following URL:
