This is my second Casio G-Shock watch.  I have had several other Atomic watches before buying a Casio and they were cheap plastic and didn't last long.  My first G-Shock lasted over five years and finally the back lighting quit working, then later I had to start charging it frequently by placing it under a lamp to keep it working because the battery was getting weak, but it was still working.  I am a Scuba diver and had used this watch on several dives without any problem.  I decided it was time for a new watch and I liked the idea of a metal band instead of the plastic one I had so I bought the MTG900DA and am very happy with it.  It looks good with the silver band and works well.  The band is well made and came with extra links so it could be made smaller if needed.  It took me a while to figure out how to remove some of the links, but a search on the net took me to a site where others had posted how to remove the links to get the band to fit their wrist.
