Did you know that the minute hand of a clock is a Vernier scale? This is because the angular displacement of the hour hand by itself is already an analog of the exact time, and the minute hand is merely an aid in reading its position, in principle.

I’ve seen some modern watches where this is not the case. It took me a minute to figure out why I was having trouble telling time. But the hour and minute hands are not true analog on some watches. the hands click from one position to the next like a second hand clicks from one second to the next.

on a standard analog watch, the hour hand moves gradually from one hour to the next so if it’s 5 til one, the hour hand is almost on the one. but not so on some of these modern watches. the hour hand JUMPS from 12 to 1 all at once when the minute hand reaches 12. So when this watch reads 5 to 1, you might misread it as 5 to 12 if you don’t look closely.
