Rich,
Take a look at the Suunto mosquito or some of the others in the Suunto line.
They do freediving as well as air and nitrox.
Many of my freediving friends,including myself use the mosquito.
Make sure you find out what algorithm it is using also.The Suunto mosquito is a little on the conservative side.
That is a good looking watch if you wanted to wear it all the time though.

I read about that watch on citizens web site. I wear the Aqua-Hyperland, it's a great watch for a timer and depth back-up but mine doesn't have computer diving built in. Their software is great for tracking dives and any other aspects of your trip.

The algorithm DCIEM which the watch uses is more aggressive than Suunto.

yeah, I'm happy with my Aeris 300G. I just ran across this and thought it was interesting.
I do see an issue of trying to operate it with gloves on. You may hit the wrong button.
