I wish, my Series 3 sits in a dresser draw as I type this. It was my first Apple watch got it at Christmas and I wore is for 6 months straight. That said I think it is fugly and I have moved back to analog watches, all of which are round. I thought I would miss all if stuff the watch did for me. Took maybe 3 days to go back to my old ways and honestly I feel better without that extra layer of non-critical notification constantly on my arm.
If and when they make a round one I will consider it.
Your analog watch is round cause the hands rotate in a circle. Digital watches don't rotate anything, it displays more than just 1-12. To force a smart watch to be round just cause original watches were functionally round is a bit oxymoron
