Hi after seeing Bear Grylls wearing the AWG-101 I had to get myself one. Anyway got this one today to join it, the Casio G-Shock AWG-101F-4AER. Could not get it anywhere in the UK but found it in Europe, the AWG-101 seems to be easy and well priced in the USA, but this AWG-101F seams hard to come by, maybe its not liked or not popular I thinks its nice !!!
