I have 12 Casio Aviators, from the GW-2000  to the GW-2500  to the GW-3000  to the GW-3500  to the GWA-1000 [2, including an RAF].
I think they are terrific watches. And what I like most, besides the sharp dial design, is that every one of them has perfect alignment between the hands [second, minute and hour] and the indices/markers. Casio has clearly perfected this alignment technology, and exceeds Citizen and Seiko in its efforts for precision in this aspect of modern watch configuration.
Perfected...until the GWA-1100. The second hand hits about half the markers exactly.
I invoked the automatic hand realignment function: all the hands point perfectly at 12:00pm.
The problem is that the dial is not perfectly set, perhaps the consequence of manufacture and assembly being in different countries [Japan/Thailand].
It is sad to see this reversion to haphazard alignment; this lack of precision cancels my enjoyment of the watch, despite its otherwise stellar characteristics. The sapphire crystal is quite nice.
The watch, despite its numerous functions, will become a gym watch for me.
