I received my GW-M5610-1BJF. I used to own a 5600 GLX and sold it right away. I thought the square was too small for my wrist but I realized it was the gloss that was annoying me and made me sell it. The GW-M5610 is awesome. I havent bought a G in over a year. I thought I was done with buying Gshocks but I guess not. lol. I almost pulled the trigger on frogman but I went with the 5610. I guess the negative display, low profile and light weight was more appealing to me. My phone camera is horrible so the photo does not justice in how cool this watch is but it's a great change from my regular watch GW3000BB.
