Well, the fully round rotor theory is interesting. That may be true - then again, there are "peripheral rotor" and the fully round rotor does block the view..... That must be a big dilemma at Seiko design department
As for the full metal bracelet - I always tell Seiko people that their watches are too cheap for what they are. They agree but their pricing strategy seems to be slowly going up the hill. Only the prices jump up is the reason why they do not make full bracelet gold or platinum watches. But there will come the days when they make full precious metal bracelet GS in the future..... For now, Grand Seiko is enjoying the position of the "most bang for the buck" king!
