A friend of mine has got a G-315RL, which is an ana-digi G-shock. He has worn it for about 1 year and now this issue has arosen: the digital time is still accurate as usual, but the hands are losing time: he adjusts the hands to the correct time and then after about 1 week the time is about 2 minutes slow! (while the digital time, and the hourly chime, is accurate). This is bad for him as he likes to read the time from the analogue.
Does this mean the battery is weak? He says they told him when he was buying the watch that the battery would last at least 2 years.
I am a bit concerned about this, cos as I mentioned in another thread, he is my only colleague who wears a G-shock and we often discuss our G-shocks and so I am sorry to see he is having problems with his.
Any ideas what the problem could be or what could solve the problem?
