I think this is a decent watch for the price Amazon is charging, but there are a couple of annoyances that Citizen should change.  I've owned mine for about 6 months and have used it in a fairly industrial environment, but have not taken it diving (nor will I since I'm not a diver).

Here's what I don't like about the watch:
- The packaging. Citizen clearly spent some serious time and probably money coming up with a chinsy scuba tank themed box.  I immediately threw this away and wish they'd have put more effort into the actual watch.
- The crystal.  It's mineral, not sapphire which means it's more susceptible to scratching.  I've seen some scratching of the crystal in the few months I've owned mine.
- The crown. Mine is very finicky and is hard to set the date; it always seems to engage the minute/hour dial.  This could just be my watch though.

Overall, I think it's a solid and beautiful watch, but citizen re-focus their efforts and have a little more attention to detail in order to make it a little better.
