Wow. Thanks @bunnypunia for this idea. I didnt know such thing even exists.
Here is my struggle and how this ring watch would be perfect for me.

I go for jogging every day and to keep the track of time I carry my mobile with me. But managing mobile while jogging is a challenge as my jogging pants have either small pockets or no pockets at all. Hence I have to carry my phone in my hand while running. And not a fan of wrist watch, so I feel this ring watch is THE SOLUTION for my PROBLEM.
