I think you should have done more research before making an advert, I would never make an advert of watch I have had for 24 hours, you don't know its power reserve, how well it runs in multiple positions etc I would be too worried that buyer will find some hidden flaws I have not discovered. You asked for knowledge here and it was given to you because everyone is super into watches and everyone is super helpful and wishing when someone scores a nice deal somewhere in the wild. I guess your biggest mistake was that you rushed too much without doing necessary homework beforehand, otherwise this wouldn't have ruffled feathers.
