Several of us have them.  They're quite nice, but they're not a dive
computer.  They don't calculate gas loading, nitrogen or oxygen.  Computers
do.

It's a high quality watch, a good depth gauge and bottom timer, and a nice
device for recording conditions and your profile.  It's not good as deep as
some computers in gauge mode, but it is good for a lot deeper than most
recreational divers are likely to venture.  There are only a couple of
problems with the watch, neither of which is particularly important.  The
backlight is poor.  If you use it during a night dive, expect to have to
strain to see anything or use your flashlight.  Most just use their
flashlight.  The ascent alarm is a bit too sensitive.  It goes off if you
raise your arm from your side to your face faster than the watch thinks you
should . . . really.  Since I don't hear high pitched noises anyway, I had
all alarms disabled on mine last time it went in for service.

Bullshark thinks that's a bad idea, at least for those that can hear the
alarm.  He may be right.  It's up to you.

At any rate, the watch is currently selling right around $300 bucks, street
cost.  Don't pay too much.

Personally i think that this watch is quiet obsolete..

For features I would go with the Suunto Mosquito that is a full
Nitrox/RGBM dive computer:

For design I would go with the new Aqualand Ecodrive:
