The whole premise is so full of win, even if it's a hoax Seiko need to jump on it and make it real. Retro is fashionable. Classic is awesome. They can't not have a hit on their hands, especially at that price point although I'd love to see Prospex and even GS models with a similar style.
In fact, cards on the table - a Grand Seiko turtle-styled diver? I'd put my money down in a heartbeat.
