I have been gifted an old family all gold Omega Seamaster 1432. I think it is from the 1970s. It is in very good condition and still has the original box (I think). It's not a watch I would wear so I'm thinking of selling it so someone who wants it can enjoy it. I have no idea about watches so I was wondering how much it would be worth and where would be the best place to sell it. Any help would be much appreciated. Thanks.
