Movie Night: How a Watch Works

I love this old movie, produced in 1949 by the Hamilton Watch Co. It explains perfectly the basic operation of mechanical watch movements. I put it up on YouTube, but better quality versions are available on the Internet Archive.

I'll do another dedicated post sometime on the topic of "fliegers," or WWII aviator watches. But here is a bit of watch trivia I just came across.

Very few watches are true-blue fliegers, but flieger styling is very popular. A rare but interesting feature of some fliegers is that they have minute/second numbers printed in reverse on the inside ring of the dial. Forumer Pawl_Buster on WUS posted an example and explained the reason for them.
    This is a feature used by WW2 pilots and Rocketeers. Basically, the watch is held underneath the mirror cavity on a sextant and the numbers then appear in the eye piece along with the other important info about trajectory etc. This allows the pilot/rocketeer to view all the info without having to look away at his watch then back at the sextant.
