There are lots of experts here.. I'm thinking of maybe selling my Zenith El Primero Rainbow (gen) in central London to one of the watch companies that buy used watches.. so I'm trying to figure out how much I should expect or be happy with.. my guess would be at least 1500GBP... I will post photos below. I have everything from the box, warranty card, metal bracelet, and a leather strap. All instruction and warranty booklets.
Maybe I will try to put it on TimeZone but I only have until Friday I guess... and am reluctant to take it to Spain when I leave on Saturday! At least I won't have the boxes etc.
