Green_Manelishi:Quickly checking the specs on a Helix shows the units are "resistant" to 50 meters. That's not very deep and I've been told by more than one vendor that to be useful for immersion at depth a watch should be resistant to at least 100 meters and 200 is better. Why do I care: because I killed two "dive watches" that were resistant to 50 meters. I killed them in less than 100 feet of 35 degree water.
FWIW, I've taken mine down to 60m (200') multiple times in warm waters. The depth display shuts off at 40m, but then comes back on once I come back up past that point. I figure I'll keep using it on all my dives regardless of the depth and when it dies it dies - it was only $30 anyway.
In the meantime I'm looking at alternatives, but haven't found anything to my liking yet. In particular I want something that displays depth and dive time, including the seconds (like the Helix), and ideally would be watch-sized, but I'm leaning towards getting an aladin tec once they come out with a new model.
