It is personal, but no case for me. I have had a SS S0, still have a SS S2 and now a SBSS S3 as well.

I do though have a see through cheap case - I put it on when I am gardening. It comes straight off though the minute I stop.

I wouldn't wear a case on any other watch and I don't see why the AW is any different IMO. Before I had an AW and had a mechanical one, I just took it off when gardening. Now I leave my AW on to gain some activity points :)

Each to their own though
