Sjors has written a 50Gs article on the sparkly Gold Defender GW-200GM-9JR Frogman. This limited edition has a unique coating on the band an bezel that sets it apart from any other Frogman. It looks great, but unfortunately it can wear off. This model has become quite scarce now, but Sjors' post is a great way to experience this G-Shock if you haven't already.
