VTG Burger King toy 1997 Jurassic park stegosaurus watch

I purchased this from an antique shop a ways back, I never got a chance to replace the battery—so I am unsure if it works. But I got it because the stegosaurus is my favorite dinosaur. From a smoke free home If someone is interested let me know and I could go get a new battery to see if it runs. Otherwise I’ll run it for less. Love it? Feel free to send me an offer
