To be honest I wouldn't sell such a watch.....
Anyhow good luck with your sale...
Don't do it....
If you don't want it anymore because you had wear and tear, wearing it day by day that's what RLX once told me for skuffs that could appear:
The more skuffs, dings your watch get's, show's RLX how much you actually like your watch, because you are wearing it confidently and consequently, day in day out and when you think it get's to a point where ot's to much for you....just send it back to our experts and a few weeks later you'll get her back shining and sparkling in brand new condition.
I don't know, I'm a watch lover, I just can't see them go
Sorry OP.
