That is incredibly ugly/bulky.
Honestly, I wouldn't be opposed to some type of bumper/cover if it could be installed and removed very quickly.
For example, if someone likes to do obstacle races (Tough Mudder, etc.) and would still dare to wear the watch doing one of those, it might be nice to have a cover that you could quickly put on before the event and take it off as soon as you didn't need that level of protection.
I don't know. Laudable concept I guess, but yeah ... fugly.
After a few days, the process of removing and putting on the bumper definitely gets smoother, but I wouldn't exactly call it something that could be done mindlessly, unfortunately
