Guangzhou 广州 SG3A 2

Guangzhou SG3A 2

The 18,000 bph SG3A movement inside this watch has what appears to be a date code, 66-3, suggesting a production date of March 1966. Colour dial Chinese watches were very rarely seen in China at this time. It's possible that Guangzhou did produce some, however. It's also possible the dial is a replacement.
