I don't know whether some people in here know this, but the G-7100 that Casio currently makes comes with an all stainless steel case with a 4 screw back bezel. I just received this watch directly from Amazon.com for $38.95. It's got a one piece all stainless steel exterior bezel case. Even the lugs where the resin watch band is attached is all stainless steel.
I love the ruggedness of this watch.
