this is my second G Shock.
The data dimensions are incorrect, and care they may surprise at first!
Casio gives 45 mm for the case, indeed it is in the majority, it's actually 42 mm (30 mm for amazon!)
The actual screen may seem small at first (only 23 mm), but you get used too.
In fact the watch seems smaller in diameter, because the thickness is hearty (not measured).
However, it is a very pretty comfortable watch, lightly.
Do not activate the automatic ignition (A.EL), this will drain the battery (no sun at this price, this is normal).
The circular metal trim to look, not gray like the pictures, but rather gray bronze going very very well in the end ...
In short, the more the door, most preferred.
I have not tested all the alarms, I would!
