Curator Response: Thanks for the report. I believe this one is likely 16 Jewels (with the upper center jeweled, but not the lower). This run occurs near the end of production of the Grade 196 and the beginning of production of the Grade 179. I think this is more of an upgraded 196, which was typically a 15-Jewel movement. The single-sunk dial helps support the 196 classification. Thanks again for bringing it to my attention.
