g shock dw6600

I bought a used casio dw6600 and the central light button is a little bit stiff and doesnt go down as much as a new dw6600, is there anything I can do to fix this? Many thanks

Hi, i want to buy a replacement bezel for my g shock dw6600, the dw6600 bezel and dw6900 bezel both fit so if you want to sell one, I pay via paypal and I'm in the UK. Also does anyone have a spare band for a dw6600 for sale? PM me and I'll reply asap Many thank
