Lol, it could work... if you have good trim. 😛
 
However, a whisky compass is more "user friendly" than the Perdex
The Perdix compass tends to wander a lot. On a change of heading it seems like it takes too long to settle on the new heading. I would have thought there would be some sort of electronic damping. A digital compass should be more stable than a whiskey compass. For that reason, I carry a whiskey compass on a retractor. The Perdix compass is a backup.

Another issue I have with the Perdix compass is that it has to be held square in front of you and in order for that to happen without removing it from my wrist it has to be so close to my face I can't see it without reading glasses.
 
Your poll is missing an option.

My job has me outdoors navigating overland day and night in austere conditions VERY regularly. Analog compass is ALWAYS your primary if you’re in the deep dark woods, and you ought to be carrying a back up analog compass too. Your digital compass is just a bonus.

You can declinate an analog compass to correct for magnetic deviation in a couple seconds, they literally cannot run out of batteries, still work if they get flooded, and if you get a good one with tritium inlays you don’t even have to charge it w a light source. It will work until you physically destroy it.

Under water: analog primary, analog backup
 
Nerd primary— it’s so easy to use!
Petrel backup on right wrist
