Welcome to the forums...
Firstly I'd forget the new so called modern LED's they are not a patch on the original 70's watches...christ,are they really £50 for these...

For a first timer its a minefield its all to easy to ripped off on Ebay if you don't know what to look for, do your homework first check the completed listing function to see what prices the watches made and the all too important sellers feedback as some of these watches can make a frightening amount of money.
By all means buy up some non-workers and try your hand at getting them going we've all been there its the only way to learn...

Have a look through here - http://www.ledwatches.net/photos.htm - this will give you a good idea of the different styles and makes of LED's that were made all those years ago.
A word of warning once you get one of these things one is never enough...
