anyone care to share about the information on this model? explored the internet but to no avail. hope some pros or anyone could provide me with its history. and a few more questions. will the water resistance of all g shocks malfunction the moment the back cover is opened up to replace its internal dead battery? or would dw-004 malfunction? and any good straps to recommend to replace the existing velcro type that comes with this model. would prefer a plastic one. good to see such a forum exist. g shock rocks.
