Yes, Nakano Broadway has amazing range of Omega. I bought a used Omega Seamaster 300 Pro (white dial) for JPY 480,000 (tax deducted already). The condition is 9.8 (with only 1 hairline on the clasp). Amazing deal 💪
Was there last june, indeed the prices were good. But have a question, does the shops remove the date of purchase of the watch if its 2nd hand, and give it a new date assigned by the shops there? In terms of resale next time, does it become an incomplete set or dubious set of sorts?
