Note: #589061 Dial is single sunken not double
Curator Response: Thanks for the report. According to period catalog descriptions and factory records, the Hamilton 940 would have originally been fitted with a double-sunk dial. While special orders are possible, it is more likely your dial was replaced at some point.
