I recently purchased and received a new G-Shock 5600 [this is the atomic, solar model with the light face and black digits].
I have placed it in a window facing the sun for half of the daylight hours for 2 days. The charge indicates MEDIUM. Hmmm. When I RECEIVED the watch, it indicated a MEDIUM charge.
Owning several other solar watches -- including another solar/atomic G-Shock 5600 [black face and light digits] that keeps a full charge with little light exposure -- I'm thinking that there may be some problem with the battery (not being able to take a full charge) or possibly a defective photoelectric cell (unable to sufficiently charge the battery).
I called the Casio service center [1-800] and the technician said to give it 3 to 4 full days of exposure to bright sunlight. He added that if it then doesn't indicate a full charge to call their service department. Fair enough -- it's hanging on a mini-blind soaking up photons....
Is this amount of initial light exposure typical for the G-5600? I don't recall that it took this long to achieve a full charge with ANY other Casio or Timex solar watch I've owned. Do I have a lemon?
