I found the article fascinating – I never knew Lindbergh was an inventor! The watch is pretty clever, you gotta admit.*
Which brings up a (rather basic) question: In the instructions for how the watch was used to find one’s longitude, it talks about finding the local time via sextant. I know of two ways to do this: 1) a noon shot (which isn’t all that accurate, and can only be done once a day), and 2) a lunar. Isn’t there a way of finding local time just using a sun shot? The only way I can think of involves a compass to find the sun’s azimuth.
