This would be my first digital since my $15 Timex from several years ago. It's nice, but I've been eyeing the G's for a little while now. I've narrowed it down to a GWM or a GW, but I can't figure out the difference. What does the GWM have that the GW doesn't? How do their sizes (the watches themselves) compare?
Also, what do the numbers and letters at the end of the model ID describe? For example, Amazon sells a GWM5600-1CR. I've also seen a -1JF. Any help would be appreciated, thanks!
