I’ve been thinking about a watch I can put on my coat or bag, which tells me time when I need to know because when it’s cold, my watch is under the thick coat and is hard to take out.
By making it look like a button, it may go well with many kinds of outer wears.
Click the face once and it displays the time and date on the glass face for a few seconds. (I figure we usually don’t need to stare at a watch for a long time.)
Solar battery panels charges electricity for the display.
