There existed watches with the same digits, features and buttons before that, but they were in steel. 1989 is about when Casio transitioned from metal to resin.

The metal watches were succeeded by the A158W, which is chrome-plated resin on the outside, same electronics module as the F-91W on the inside, and likewise is still in production.

After the resin case of my A158W eventually broke, I got a vintage W-34 with a broken movement and put the A158W's module inside. (It will get a SensorWatch PCB once I am done with my firmware mods)

Steel replacement cases for a F-91W are now also available on Aliexpress, so you don't have to hunt down a vintage watch if you want real steel.

I had an F-87W [1] when I was a kid, which was launched in 1982. It is almost exactly the same as F-91W.
