I wear a Timex digital watch when I travel instead of my Apple Watch. This is a simple digital watch where the numbers are made from segments of a bisected square. As I was traveling through the Caucasus Mountains this was the only way I knew what time it was. I really only needed to know that time for breakfast and dinner in our guest house, but I like to know what time it is. Even in the middle of the night. On one particular night I was unable to read my watch. I couldn’t see the numbers. I could only see the negative space between them.
