I have a lovely old pocket watch that I used back when I was
holding forth in front of a classroom -- leaving it on the desk before
me, I could pace the presentation without looking at my wrist
repeatedly (and the face is large and clear enough to be read easily
at a distance). It's a 14 karat Elgin Crusader with a G.M. Wheeler
17 jewel movement just like the watch pictured here.

Using this lovely Elgin Watch Collectors Site I was able to look up
the serial number and thereby glean a deal of esoteric information about
the watch (e.g., the movement is a grade 452 made in 1926, and it ticks
five times per second). I think I may start using it again, if only on special
occasions.
