When Casio announced the used of a new technology called the Carbon Core Guard (the case is made of fine resin that incorporates carbon fiber for light weight along with rigidity that is superior to that of resin), I had to have one for the collection. I chose the GA-2000E-4DRas this is the only model available that came with two additional straps. It is also has analog-digital display which appeals to me personally.
I must admit that it took me a long time to finally get this watch. What made me hesitate is the use of battery to powered the module. I have a (irrational) dislike for battery powered watches as I tend to associate battery power with mass-produced basic timepieces.
I don't hate quartz movement per se. I am fine with solar powered, kinetic or even spring drive quartz movements but not if battery is involved. It is because I happened to suffer a number of battery failures over the years (not in watches) which caused destruction due to acid leakages. This phobia remains.
