Casio CA-53W

Module 3208

Factory Spec. 15 SPM

Classic calculator watch in very much the same style as the one I had as a kid, except my original had a flat panel of buttons, instead of the raised rubber buttons on this one.

This watch serves as my primary stopwatch for timing my HAQs.


Some details of this watch may be missing as it has not undergone comprehensive testing.
