Description
These are very cool watches. The Gruen Day-Night has a rotating disk that changes all the hour markers black at midnight, then green at noon. This watch is all original and came from its only owner. The case has corrosion on the sides and rear. We always find these with exterior corrosion. The manual winding Gruen movement is in excellent shape and was just fully serviced and is keeping accurate time. This gentleman wore this watch daily since the 1960s. The original dial is amazingly preserved, as are the original hands. This watch looks fantastic on the wrist. These are uncommon watches.
