The forums that stick to one brand are ok if you're looking for specific information, but other than that they spend too much time crawling up their own backsides. I find the general forums more interesting.
I've used THIS GUY in the past, his previous site was called HeuerBoy.com. He's very reliable, knows his stuff, and I would have no hesitation in dealing with him again.
My Dad had an old Citizen Duel Ana-Digi watch which he wore everywhere. Unfortunately it broke and Citizen were unable to repair it, so after searching the net, I found this bloke who had a mint condition version for a lot cheaper than the top price I was willing to pay for it. All in all a great purchase.
Apologies if this sounds like a bad eBay feedback
If nothing else, visit his site to check out all of the retro watches. If you want class, go for a Tag Heuer Monaco. If it's good enough for the King of Cool, then it's good enough for us.
