Hi Bretta,
What you got there is not really a Weems, this kind of watch is missing the 2nd crown devise (thread in case).
Further it is missing the cut out area at the case top for the L-shaped locking device.
My guess: This kind of watch is a pre-Weems attempt, without the 2nd crown feature.
As a teaser: Once 3 complete Weems cases in NOS were offered on Ebay just the locking devices were missing, guess who catched them. :p
