Serial Number 4847786 was reported as inaccurate.

Note: Someone had asked about a watch with serial number
4847786 at
https://www.reddit.com/r/pocketwatch/comments/1czz
8qs/anyone_know_anything_about_this_pocket_watch/,
and it came to this page, but something is pretty
clearly wrong. The movement in question is not a
model 3, but a model 1. This also seems to be the
case for most movement images listed alongside.
Seems to me that either the model is wrong for the
grade, or the grade is wrong for the serial
number.
