Casio A168WE strap clasp problem – keeps loosening over time

Hi,

I have a Casio A168WE watch that I really love, but I keep running into the same issue: after a few months of use, the metal strap clasp doesn’t close properly anymore. It seems to loosen over time and eventually won’t hold securely, which makes wearing the watch risky.

I’ve even bought several identical models to compare, but the same problem happens every time.

I’d like to know:

• Can I repair the clasp (tighten it, replace a part, adjust it)?
• Or do I need to replace the entire strap?
• Is there a long-term fix to stop this from happening again?

Thanks in advance for your advice
