This is quite old. It has been stored away for a long time, but I wound the spring for the purpose of listing it, and it is running. I'm not sure if it's working correctly. The dial is quite small. Overall: Approximately 20cm Would anyone who likes antiques be interested? As it is old, there may be natural age-related deterioration, stains, and discoloration (yellowing). Please understand this before purchasing. Returns are not accepted. There is no box.
