I just got this CFX-200 for $50...
(I'm not sure why, but in my country they are cheap) and it's working great, even its little backlight... BUT 2 buttons are not so responsive (1 and exe), I have to press them a bit harder to make them work.
So I have some questions...
1: What do you think is happening? just dirty or some module malfunction?
2: How do I clean it?
3: Well, my idea is to strip it down, then clean both, the metal parts and the module, but how do I clean the metal parts?
And 4: What other watches have the same kind of buttons? I need to replace some of them.
thank you very much!
