My Casio stopped working after a decade...

I bought this Casio AE-1200WH (module 3299) back in 2014, and it’s been with me through so many moments in life...Wore it daily until about two years ago when I switched to another watch. Today, I randomly took it out, only to find that it’s completely dead...

Not sure if it’s just a dead battery or something else, but it feels weird seeing it like this after all these years...this watch was a part of my everyday life for so long, and now it just stopped....
