Hi all. It is generally known that any electronic device however robustly built will lose functionality over time due to decay in its circuits. Keeping that in mind, I would like to know how long do G-Shocks last until they need some replacement of an electronic part (not talking about the battery)? For example I have seen problems develop in the LCD over time in many of the older Casio digital watches. With regards to this could people share their experiences with G-Shocks?
