This is a retro, hand-wound SEIKO 17 JEWELS wristwatch from 1970 (Showa 45). Currently, it loses about 50 seconds per day when laid flat. Please consider the accuracy as a reference, as it varies depending on the winding state of the mainspring. How about one as a fashion item? Since it's a mainspring-powered watch, battery replacement is unnecessary. Maintenance is actually easier than using a battery-powered watch. There is no water ingress inside, so it seems usable for the time being. The case dimensions are 26.5mm wide, which is slightly large. I think it's a size that's not too small and easy to use. Features: Powerful design from 1970. Hand-wound. The red seconds hand and date also give it the feel of a foreign-made watch. There are minor scratches and dirt from use, and scratches on the crystal. The glass crystal has been polished with a special polishing agent, so there is generally no cloudiness, but some scratches remain. Operation has been confirmed. The accuracy is generally accurate when checked while laid flat. The belt is made by Bambi. The maximum belt length is about 169mm. For shipping reasons, the belt will be sent detached from the buckle. Hand winding OK Date setting OK The date can be advanced quickly by pulling and pushing the crown.
