Citizen watch best Parts/Restore

Product Name: Citizen watch best Parts/Restore
Up for grabs is is a vintage citizen automatic watch men. The watch does work but does have some issues. It's does not wound up due to broken stem but it does start when lightly shaking the automatic rotor. It is NOT a screw down crown. Not waterproof, so I wouldn't try it under water. It seems as if the previous owner had it serviced back in 2016. The bezel does turn but it does have a stiffness to it. Maybe it needs some cleaning. Stem to the crown broke off. Parts/Restore. Before the stem broke, the watch was telling accurate time. It's definitely a restoration watch. 40mm excluding crown 20mm band 13mm thickness best.
