Serial Number B640544 was reported as inaccurate.
Note: Further to previous I believe this to be Hamilton
as it has Hamilton Stud, Hamilton click, and the
movement retaining screws are sited differently to
Ball Walthams that I have, also it's 21j

The Ball organization "forgot" that they had
Waltham suppy 17J & 19J ORRS mvts in 1903 bearing
S/Ns B640001-B640800 & 17J Commercial Standard
mvts S/N B640801-B641000. In the 1930s they had
Hamilton duplicate the S/Ns on 16S, 21J ORRS mvts.
Keep up the good work, Kent Singer
