My old Casio watch, on its second battery, was a half hour slow when I
woke up this morning. New battery or new watch? In the past, when
battery failed the watches stopped.

Oddly, since then the Casio has kept perfect time. I'm wearing it again.
Wonder why it lost a half hour? Never had that happen to a battery watch.

Maybe the battery contacts are corroded. Clean them (and the battery)
with a pencil eraser.
