Is it normal for Casio watches to become foggy when the weather is cold?

Hello, I am happy to answer your question:

I have never had this problem with the one I bought in Casio’s official store. I suggest you consult Casio’s after-sales service directly to avoid missing out. Best time to repair.

Of course, there is a situation where mechanical problems can be ruled out, that is, you go from a suddenly cold place to a suddenly warm environment. Then, it is normal for water mist to form on the glass surface.

If water mist occurs for no reason under normal temperature conditions, repairs should be made early to avoid affecting the operation of the movement!

Please adopt it if you think it is helpful to you. If you still have any questions, you can continue to ask, thank you!
