I bought one just like this when I was a kid back in the '70s. Digital watches were a big deal back then! Plus you could press a button and light the dial. Pretty cool stuff! I really wanted a calculator watch, but it cost way too much.
I am not a big fun of the digital watches, I sold all of them from my collection, but I needed a watch for outdoor activities...
@marszab Yeah. I bought a Citizen Satelite Wave to use when there's any risk of damage.
