This is the perfect mod for my Casio calculator watch. Although now I want to do this to ALL my digital watches. Guess I have work to do now. Thank you for great mod idea.
Awesome! I like this a lot. Do you think this sort of modification would be possible with a Casio CA-53W? I just got into watches and this one is great, but I'm finding the absence of any backlighting very annoying. Thinking this would be exactly what I need but I'm unsure how to go about it.
this lume wont charge from the led, i do this mod on my dw5600 too which is el backlight. still not powerfull anought to charge the lume,it still need to be charge from direct sunlight or some torch. the calculator watch have a very small display i dont think its a good idea to mod this background lume on it, if you have the new reissue one which is negative display. the only best mod is positive display it. but if you want to give it a go as part of your watch antusiast journey, just do it. but make sure you know all the teardown and asamble process. and dont lose any small things. there's alot of video on youtube show you how to do it. have fun wit your mod.
