Serial Number 21826 was reported as inaccurate.
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
pjackmac123 *****@gmail.com. Thanks. Andy
