I am looking to buy a dive watch of course, and I just wanted to say, in response to this thread, that although I am interested in a D3, I doubt I would even look at it during a dive, and I sincerely doubt that it would influence me to push too hard. My interest in a dive watch is to be able to reveiw my dives at the end of the day and learn from a mathematical perspective how to improve my technique. I don't think it is a compensation phenomenon, nor do I feel it is a waste of money. I usually dive alone, and rarely time my dives. It is the only way I know of to examine my progress.
