This is a listing for a Seiko Crown with 21 jewels. The movement is running well. The crown is genuine or a similar type. There is age-related deterioration, but the movement is in good condition, and I believe this item can still be used for a long time. The crystal does not have any noticeable scratches and is in relatively good condition. Due to the age of the item, I cannot guarantee accuracy, but I have attached the values from the Timegrapher app in the last image for reference. This is a vintage watch, and I am listing it under the "scratches and dirt" category to prevent any issues. I am selling various vintage watches as I am organizing my collection that I have gathered over many years. There are many images, so please be sure to check them before considering a purchase. I will ship via Yu-Packet Post.
