    Did I overcook my module?

    I recently received my new GW700BDJ-2 [BTW it's awesome....the all-steel G-Shocks are definitely serious pieces of work] and decided to put it under my halogen desk lamp to get it starting to charge up [it was flat on receipt, and too late in the day for direct sunlight].

    After a few hours I checked it and found that the light had heated the watch waaay up...it was too hot to touch and the LCD was blacked out. I let it cool and the LCD came back to life, but now I see that the display is dim and a little hard to read in normal daylight, unless I turn it just right to reflect the light. All the other functions seem to be fine...the atomic clock radio signal has been absolutely reliable, FWIW.

    Is this normal for the reverse LCD displays, or did the heat weaken the display?

    As it is, I am thinking of replacing the module with a regular non-reversed LCD...is this feasible to do myself? Can I even order new modules from Casio, or elsewhere?

    Any advice would be appreciated...

    token not sure but it could be it was got too hot and still did not get charged all the way i would give it another day not in direct sunlight. I have heard about someone putting there g in a glass of water to keep it cool while it was charging. again i would give in some time to charge

    Yes, reverse displays are significantly more dependent on proper viewing angles than regular ones. That's why many folks here don't like them.

    It might still be cheaper to order a new watch and swap the modules. At least in my GW-810H it was very easy to remove the module from the case. It's not really more difficult than replacing a G-SHOCK battery as long as you take some care not to leave dust or fingerprints on the display or the inside of the crystal.

    However, I would only try to swap it with the same module type, just with the opposite display. Other modules might not fit snugly in the case or have different pusher positions.

    Using a second module donor watch has the positive side effect of having two functional watches...

    Hi Token,

    The same thing happened to MTG-911DMS last year when I placed it on the balcony of my family apartment for charging. The sun was strong and the watch was really hot, in fact the LCD also blackened. However, everything returned to normal after it has cooled down.

    The manual also stated that the LCD would return to normal after the watch has cooled down. So, no worries there.

    Cheers,
    MountainMike

    Re: Did I overcook my module?

    Gentlemen -- Thanks for your advice...

    Jersterca -- Actually, the watch charged up to full without any problems...I was aware that it takes a while to get there [and after a few days of sunlight it did], it's just that I was impatient the first evening.:oops:

    MRG-1000 -- I was advised in another thread that the non-reverse LCDs were better for visibility, but I didn't realize how good that advice was. In any case, I REALLY like the colour scheme of the 700BDJ, so I wasn't inclined to listen.... I've considered getting a second watch and swapping modules, but I thought it might go cheaper to order the bare module from Casio. Believe me, there is no shortage of functional spare watches around Chez Token . It seems to me that the EL backlight is also very dim, but that could just be my middle-aged eyes letting me down.

    MountainMike - Yes, I read that in the manual too, but since I didn't really have a good idea of what the display was like before the, ummm...heating incident, I wasn't sure if practically cooking it under a high-intensity light fell into the same category as too much sun or other natural source. There is evidently no way to tell what the normal display should look like based on the sales promo pictures ....

    It may be that the battery, though showing fully charged is not, or is weak. If it was flat, it would take more than a few hours under a lamp to fully charge. It takes many hours in full sunlight. I would give it some more light time. If still a problem, consider a battery swap.

    The intention is understood. I was rather trying to point out that getting a good deal for a new watch might still be cheaper than a spare part module. I've seen spare parts being sold for horrendous prices.

    You should get a quote regarding the module's price before making a decision.
