For most diving I have my computer on my right wrist and my watch on the left. My compass is in a console with my spg and depth gauge. Works like a champ. This is especially good for live boat diving. Everything I need to navigate, control depth and monitor gas level is in one place. Left hand with watch on the wrist is holding the console with everything else. Occasional looks at right wrist with computer. Or, at night hold light with right hand to see everything in left hand.
I got to this after trying various configurations. I suggest you try wrist, console, separate mount on lanyard, or whatever. Use the one that works the best for you.
