This is an important concern.
You should try to maintain an equal amount of drag on each side.
Perhaps you could add another garmin to the other arm (it doesn't have to work).
Otherwise in open water, you might end up going in circles.
However
It does depend on whether you are right or left handed.
Right handed people in an anticlockwise course loop, might gain a small advantage.
Left handers would benefit from a clockwise loop.
Obviously both wrists, for an out and back. (or switch at the turnaround)
You point out that it is usefull to be able to observe your pace.
Usually (swimmers) in a race it is advisable to go as fast as you can for the distance.
If you can go faster you are going too slow, if you can't go faster, checking your watch won't make it happen.
Hope that helps. :0)
This is the most sensible answer here ever bar none. To add, if the swim is clockwise like IM Mont Tremblant, wear the watch on your right hand so there is more drag on the right and will make you turn the buoy easier. For IM Lake Placid, which is counter clockwise, wear it on your left, for the same reasons. Personally, since I put my Garmin underneath my swim cap, I shift my big toe out on one foot to increase drag on one side and assist during the turn.
