need advice on buying my first seiko(s)

I’ll echo the sentiments above: head to Ginza. Wako has the largest selection of high-end Seiko (Grand Seiko and Credor) anywhere, including several exclusives and even a custom-build section and mini museum on the first floor. Half a block west, on the same side, there’s a boutique covering all the other lower-end brands - 5, Prospex, King Seiko, Astron etc.

The discount stores (Bic and Yodobashi) will have the best prices, but generally have limited Grand Seiko and no Credor. They also generally have no or fewer LEs.

Always bring your passport for instant tax-free, and ask if there is any discount for paying by credit card.
