NATIONAL WATCH DAY !
I always wear a watch. My watch if choice is a Casio Calculator watch. It’s water resistant (I’ve been through a few, pushed my luck)
It’s digital and boasts all the buttons a regular strength calculator would feature. According to Wikipedia, they were first introduced in the 1970s and continue to be produced, despite falling from their peak popularity during the 1980s
Thanks watch, for always being around for me to check neurotically !
