Only two in the post for me (and a couple that I may buy off a mate ...) Collecting G-Shocks is a lot cheaper and easier than my other main hobby, collecting military vehicles and tractors.
G-Shocks take up far less space, deteriorate a lot slower, don't require fuel to be played with - though I am looking at a bulk buy discount for CR-2016 batteries - but are well supported with a load of forums and information on the net, are readily available, have a loyal following, require a certain amount of satisfying maintenance and have some fascinating quirks and features amongst the vast spectrum of models and styles.
So why not collect G-Shocks? Many compare favourably to the price of a night out at a restaurant, pub or cinema or the price of a football ticket and provide lasting pleasure.
Go for it! :victorious:
