I think it depends. A 'worn' look I can quite like, but if it looks like it was worn by something off an Evil Dead movie and it has flaps hanging off, I'm not too keen. :-dNo way, I prefer a brand new look.
I've seen ppl wearing beat up G-Shock and it looks terrible.
I couldn't have said it better. This goes for me too. When new I often even don't dare to wear. When I wear them a few days, it becomes one of my beater watches.I like the brand new look, and also the naturally aged look. I wouldn't deliberately age one, I'd rather enjoy it looking new, then in time enjoy it looking used.
