The Elgin 524, which was made in the 1930ies about 150000 times, is very well made movement, which pleases aesthetically and especially technically.
What you immideatly see is, that all (really all) bearing jewels are enclosed in chatons (golden-toned metal bushings) instead of being pressed directly into the plates. If ever a jewel has to be replaced, a chaton makes it much easier for a watchmaker.
The balance part is also high-quality: The two leg balance (not yet shock protected) contains golden-toned regulating screws and its hairspring is a breguet-type hairspring with its specially shaped end. Its effective length is adjusted by a long regulator arm.Video on YouTube
If you’re familiar with swiss movements, you will be a bit astonished by the plates here: While the small gear bridge houses only escapement- and fourth wheel, the large mainspring bridge not only houses the mainspring barrel and the minute wheel, but also the third wheel.
The angled brides are another indicator of a high class movement.
On the dial side, you see the yoke winding system with its uniquely shaped setting lever spring.
