Gruen Precision Diamond Quartz Watch

Got this vintage Precision by Gruen watch. It's a quartz movement with a nice oval face and a little diamond accent at the 12 o'clock spot. The gold and silver tones on the band give it a cool two-tone look. It has some wear and scratches on the metal from being worn over the years, but it's still a classic piece. Not sure if it needs a new battery or not, selling as is.
