Serial Number 11807 was reported as inaccurate.

Note: A note on the Hunter case: It is engraved for my
great grandfather from the engineers of the
Birmingham Southern RR, May 1, 1907. Could it be
that the watch was originally made open face
(circa 1899) but with the stem at 3 o'clock
instead of 12 and later those engineers re-cased
it in the nice 14K Keystone Hunter case it now
has?

Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.

Serial Number 11807 was reported as inaccurate.

Note: The database listing above says
Movement Configuration: Openface
which is wrong. I own this watch and the
configuration is Hunter. It is in a 14k Keystone
case. Thanks.

Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
