SEIKO Seiko ACTUS Actus SS 6306-5000 Automatic 21 Jewels 3 Hands Day-Date Square Wristwatch Silver Dial I believe this is from the 1960s to 1970s. This is an item being sold as part of a decluttering effort. I received it as a used item and have been storing it. I am not very knowledgeable about this item, so I have not performed a detailed operational check. It starts running when shaken, so I believe it is an automatic watch. The time, day, and date can be changed by pulling out the crown. I have not checked anything else. There are scratches and scuffs. The buckle on the belt is warped and I don't think it can be attached. Since this is a very old item, please consider it to be equivalent to a junk item. Therefore, we do not accept returns or refunds. Please also understand that there may be errors in the product name. We are not responsible for damage caused by accidents during shipping.
