Over on Yahoo Japan I found some Bull bars for sale
I know it's a ProTrek in the photo, but it says they are also doing it for the GW4000, GA1000, and the GW9300.
I found it when searching for watches. No association with the seller in any way, I know some people are really into bullbars, and you rarely see them for sale. Anywhere. And I don't think anyone thought of them for any of these watches. In any case, Google translator also says you get to pick the color. Have fun!
