Hello I have recently aquired a new crystal for my w-24 marlin and wondered if anyone could give me a few tips on how to remove the old crystal and put the new one in? many thanks

Thanks for the reply casioguy helpful as always, i will use the original gasket because i definitely wont be going swimming with this watch!

I have the same experience, bondfan.
I recently replaced a crystal on a casio marlin ,i used the old gasket because when using a new gasket you need special tools.
And as casioguy says, we are not going to swim in the sea with these oldtimers and risk busting them :lol:
