The backlight in my GW700DE (module 2866) lasts only an eyeblink, and the 'RECOV' message blinks for a lot of time. Battery indicator is in 'full charge' (and has recently been exposed to the sun of greek islands, so I think it should really be in or near full charge).
By contrast, when watch was new (7 or 8 years ago), the backlight duration was about 1.5 seconds (still disappointing, but that was what mother Casio did).
Watch was worn practically continuously until some months ago, when I switched to an analog watch, and kept it in a not-so-lighted place, used only to check time of other house clocks (it's radio controlled). Then I restarted wearing it during holidays.
Should I have the battery replaced (will bring it to a Casio dealer for servicing) ?
Worth have also gaskets replaced ?
Thanks in advance for your advice
