If you want a Casio watch and are traveling to Japan, just get one at a second hand shop there (WonderEx, Second Street, ...). They are tend to be well stocked on the Casio cruft.
I have a Casio PHYS STR-800, nonworking. I got it two decades ago because of the large lap memory (and unusual look, too); I was doing a lot of running, including track training and such.
It short circuited one day. Put in a battery, and it drained the thing in a minute. Put in another one, same thing.
It's been sitting in the top shelf of a bathroom cabinet since like 2011.
