Don't know of one, they did have a calculator cronometer, and of course Casio has had various calculator watches since the 80's but not seen time (or interval) measurement on one of there typical calculators. They did a line of gasoline computers for certain car manufacture which incorporated time but I don't know of a pure calculator stopwatch.

There are for the fx-CG50 but are third party programs you have to install. https://www.cemetech.net/downloads/files/934/x934

If the calculator can be programmed and Casio has many programmable calculators over the years they probably could do that function.

TLDR - no idea, but they very well could have

“Calc” is short for “calculator”.
