  1. How Does Casio Achieve Water Resistance With Their Watch Backs Attached Via Screws?

    Casio G-Shock
    I have noticed that all G-Shocks and even the better Casio's like the Oceanus have watch backs that are attached via screws. They usually have high water resistance 100-200M in most cases. I have also noticed that most dive watch's backs are screw down style. So how does Casio achieve this...

  5. Casio Oceanus is the best deal and hidden gem amongst Japanese watches

    Public Forum
