Serial Number 21826 was reported as inaccurate.
Note: My watch has serial number 21826. The movement is marked U.S. Watch Co. (across the top) and Waltham Mass (on the bottom). The serial # is in the appropriate place corresponding to the pictures on the PWD site. However, my watch is clearly Jeweled. There are four pin protrusions in the full plate movement. All four are jeweled. The PWD site has my watch as a seven Jewel movement. I dont think that is accurate. My email is pjackmac1234@gmail.com. Thanks. Andy
Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
