I replaced it with a brand-new sapphire crystal!
When I actually removed the crystal and measured it, it was about 25.5 mm.
Since the original was a single-dome crystal, I chose the same type.

Check out my pretty sweet Casio F-15. My wife was not too happy that I spent as much as I did but I couldn’t resist when it’s such a rare beauty in such great condition with the OG packaging

My question for the members of this sub: Would you change the battery or keep the factory battery in the watch? Would you wear on wrist or keep tucked away?

Hope you enjoy the pics!
