Thank you for viewing. This is a later model that transitioned from the small seconds type to the center seconds model. It's a model that was designed with SEIKO, the industry leader, in mind, and was a popular model at the time, pursuing a long stem, large rounded lugs, visibility, and beauty. The early models did not have a shock-resistant device, but this model is a later model with a shock-resistant device. Regarding the condition, the caliper is also working and clean, and the dial is new. The case is in good condition without any major scratches. This type from this era does not have water resistance, so most of them are damaged, but this one is in very good condition. The size is also a 14-type: Length: 42.0mm Width: 34.0mm Making it an easy-to-wear size for an antique. - Brand: Citizen - Model: 17 JEWELS - Function: Hand-wound watch - Material: Stainless steel - Features: PARA SHOCK, PHYNOX - Country of Manufacture: Japan Thank you very much.
