Serial Number B635190 was reported as inaccurate.

Note: I had a hard time reading the serial on this
movement. The website has been changed since iv
been here last. I dont see a contact link or a
home page. The ser# lookup has malfunction when
using a smartphone. Anyway my movent says Ball
Watch co. Cleveland, O. Also says official
Standard. I dont see 992 any place. I own other
992 hamiltons but this movement size 16 does not
say hamilton at all. Would like for you to look at
it and tell me if i got ser# correct. Truth is iv
been not collecting much any longer since i had
health issues and my vision has declined. Hard to
be a pocket watch maker with neuropathy in the
hands and poor vision. I do miss it though....tnx.
