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!

Changes since this report was submitted:

Grade changed from Unknown to 44

Jewels changed from 11j or 15j to 15j
