We noticed that you entered a relatively short serial number.
"642" could possibly indicate the grade of the watch and not the serial number of your movement. Serial numbers are usually more than a few digits.

Note: Mine says 19 Jewels on it so I looked it up in
Complete price guide to watches and they did make
a 19 jewel 936 and is a 4 star watch.
Curator Response: Thanks for the report and images. The "19 Jewels" marking is post-factory, likely added by a retailer or previous owner. Have you been able to confirm that the movement contains 19 jewels? Typically, post-factory markings like this are not representative of the true jewel count. Thanks!
