Given my requirements which computer should I lust for?

Requirements:

Wrist computer rather than console.

Air & NITROX

Biggest display with biggest numbers possible

Most interested in seeing (only) depth, bottom time remaining and huge ascent rate display - Audible alarm would be nice too if it is seriously loud. I have severe tinnitis so this may not be possible. (I can't hear the Minature Ascent Rate Alarm - MARA.)

Would rather not have display of nitrogen loading graphic, O2 saturation graphic or any other crap on the main display.

Do not want air integration.

Aeris makes a nice dive computer fitting most of those requirements.

Think I found exactly what I'm looking for. It's the Mares Icon HD. Has the huge ascent rate scale that goes from grey to red if you exceed and ony the info that I want on the display and none of what I don't want. Display is very well laid out as well. I'm in lust.
