Vintage Seiko retailer SQ Quartz Watch

Product Name: Vintage Seiko retailer SQ Quartz Watch
Vintage Seiko SQ quartz watch. Cleaned polished and new battery installed. Watch is keeping accurate time. The back part of the clasp in watch is loose as shone in the picture but it doesn't hinder the retailer watch from closing and and staying tight on the wrist. There's a tiny surface scratch on the glass that can only be seen in the right angle and light.
