Can the ROM be read and flashed back on Casio watches?
I once bought a solar G-shock but the watch UI is horrible: it does not display the battery charge anywhere on the watch. Instead, it wants you to install a Casio app that connects to the watch via BT. However, even the app doesn't show the battery charge with more than a few scrambled pixels in a small icon. So, useless.
I still don't know how much battery I had left at the time: I eventually got a low battery warning during the winter with no good sunlight to charge it and so I forgot about the watch. You would think a solar watch would want to boast with a highly visible battery level indicator on the screen, and also because it would be a very useful thing.
If the ROMs are hackable I'd be interested in looking at the assembly if for nothing else but to fix that battery level indicator.

Example: https://www.otto.de/p/casio-g-shock-funk-multifunktionsuhr-gw-m5610u-1er-C895781477/ https://www.otto.de/p/casio-g-shock-funk-multifunktionsuhr-g...
- yason 5y agoNice, thank you! I might actually consider upgrading, I have no other complaints about G-shock. It is somewhat bizarre though that a watch in the 2020's lists a battery indicator as a feature... I had an analog solar watch before. While it was beautiful it couldn't take the beating I seemed to give it time after time, and gradually the hour dots were broken loose and one of the indicator hands also got dislocated. Thus, I decided to try the digital G-shock with no moving parts and it was great. No matter where it hit, nothing broke. Got dirty? Wash it while showering. No problem. Now if it comes with the battery indicator then I must simply choose another thing whose ROM to dump and disassemble :)
- SamReidHughes 5y agoPractically all solar powered G-Shocks have a battery indicator (lo/med/hi) that's visible all the time, this isn't a new feature.
