The models are G5600CC-2, and G5600GR-7. Somewhat older, but new to me for sure. I promised pictures in the 5600 bezel thread, but didn't want to hijack that thread anymore than I already had.
The G5600CC-2 is in the best condition I've ever received for a watch off of eBay. Very clean, virtually brand new except for one tiny nick on the screen.
The G5600GR-7 is from the "Going Green" series Casio had back in the day and originally had a white band/bezel. However, the band/bezel came in well used condition. The case itself is in great-excellent condition with minor marks on the glass. I replaced the original band/bezel with a GLX-5600 set in glossy black (which I like better anyway, makes the green standout more).
These are great additions and are very enjoyable to wear. I am very impressed with the G5600CC's display. It is a negative display, but it is blue, and somehow it is more readable than other negative displays I have seen, even off angle. It can handle low light better as well, but still not as good as its cousin. The one negative to the G5600CC is the backlight. Instead of making just the digits light up, Casio stuck with the whole face and in turn causes the digits to not pop out separate from the background as much as it should.
The band/bezel for the G5600CC is just great to look at and I didn't expect to like it this much. My plan is to stealth the case by replacing the bezel with the bezel from a GWM5610-1B and then add strap adapters to use a black PVD zulu strap. I am still going to do this, but I will be swapping back and forth between stealth mode and blue mode more than I thought.
There you are folks! Hope everyone is in good health!
Edit: not sure why the G5600GR pics ended up separate from the other pics, but as long as you can see them that's what really matters!
