I've just picked up a G-9100 and have noticed that the display looks slightly misaligned. It is very slightly anti clockwise. It is noticeable because the line on the LCD below the date window is not parallel to the top of the tide frame window.
I removed the back and tried to move the pivot the whole module within the case but there wasn't enough movement. I put the back on and decided not to go any further.
However, reading other posts here on the 5600E it looks like the module can be lifted out as one assemble. Is this the same on the G-9100?
