Anyone know anything about this Grand Seiko? (9F61 OALO T4)

Hey all. Recently I've been thinking back to my last trip to Japan. I tried on many many Seikos in Wako and the various discounters, but the one I like the most was this quite discrete quartz number. It was about 38mm, and super thin. I've googled the model number, but I can't seem to find anything about it. As the photo was taken in Shinjuku, I'm assuming I tried it at Yadobashi Camera...

Is it a discontinued model? JDM? Any info greatly appeciated as I remember being quite taken with it, and that it was quite reasonably priced...
