Question: are grand seiko better than rolex?
Answer: No — they're better. The only respect in which Rolex is better than Grand Seiko is brand prestige, but that's it. The dial finishing between Grand Seiko and Rolex isn't even close — GS is much, much better. GS also has a high-end branch in Credor, which makes movements that Rolex simply is incapable of making.
