I think I've found my next watch, I don't think I can find an affordable Seiko Spork, but the new Orient Mako II comes mighty close, with an updated hacking/winding movement too.
Only one small problem, the Blue version is out of stock everywhere at the moment, unless I want to pay the price from Orient's own shop, which I don't. I'll just have to wait until someone has it back in stock.
