It was my first Grand Seiko, which I bought in 2008.
Fantastic model, with a significantly better finish than the equivalent Rolex 16570 (which I own and love).
My only two knocks on that model, which lead me to eventually part with it, were the lack of micro-adjustment at the clasp (a real pet peeve of mine) and the case being a bit on the thick side. But otherwise a masterfully executed GMT watch.
