Serial Number 130832 was reported as inaccurate.

Note: Maybe Grade 44?
Curator Response: It is either a Grade 44 (15 Jewels) or Grade 46 (11 Jewels). Unfortunately, this was during an era of production when these two grades looked nearly identical from the top plate, leading to ambiguity. Let me know if you are able to verify the correct jewel count under the dial. Thanks!
