Serial Number 1946000 was reported as inaccurate.

Note: This is an open case watch, not a hunting movement
configuration. That is my thoughts on that.
Also, I noticed that the watch is cased and timed
by Elgin National Watch company. Also, the case
is rolled 10kt.

Serial Number 1945899 was reported as inaccurate.

Note: Correct model is 5, it is a three finger Getty
Model. Also, I thought RR grades pocket watches
had to be adjusted to a minimum of 5 positions.
