This is a yellow GW-400HLJ-9JF Hawaiian Lifeguard limited edition that came in recently and it's very nice. There aren't too many of these available here in the US. They were released mainly in Japan and Hawaii. It has all the basic features of the Silencer models, but comes with a unique yellow band and bezel, along with red and yellow text on the watch face. There's not too many non-stock photos online of this model, so here's some photos for anyone wanting to take a look.
