I have a bunch of Gruens, I think they made some great looking watches. This is not one of them.
This is currently the only quartz-movement Gruen that I have. It's "unisex" size: too big for ladies' watch and too small for a men's. The markers are luminous. It's fairly easy to read and it runs, but I don't care for the look of it.
I'm not sure how I got it, but I seem to think it may have been my maternal grandmother's watch.
