+1, totally unexplainable....the guy is nuts. Make sure you weigh the envelopes and make a photo while they are unopened on a scale as proof for paypal.
Simple, just weigh the watch or another with the same weight and give this with the video to paypal. It will prove that this scumbag did not send anything but an empty enelope
if you are not familiar with taking watches apart and more important, putting them back together again, I would suggest a local watchsmith who is repfriendly...don't go to an AD as they are not repfriendly for sure.
there are some vids on the net replacing hands if you want to have a go at it...
all about personal taste, RG and RWI house a lot of RMlovers....I think they are stunning designs but I would not put it on my wrist....Hell, I said that same thing 10 years ago about Rolex, I got a strange sensation few months ago and now own about 12...😉
