Gruen Watches- For Parts or Repair Square face gruen has no glass on front The gruen face on the right has no back - but 2 back pieces are in this lot not sure if one is for that watch, I'm no watch repair person, maybe I wasn't lining it up right. But one may or may not fit. The Embassy by Gruen on the left would need a battery. & The inside of the band is tarnished or worn. - (refer to pic 2) Please refer to all pictures for visual detail as they are considered part of the description as well.
