One of the cool things about watches is you don't have to be mega rich to have fun if you're a bit of a tinkerer. I've just bought around 350 grams of digital junk on eBay for an undisclosed sum (=less than a new G-Shock) and I reckon at least one of them will work. That's because one of them (the Soncor) works. As for the other eight watches, some of them are new old stock but they've probably been sitting in a warehouse somewhere so I'm not sure. Anyway, I will keep you posted with updates. Cheers!
