1960s Gruen Day-Night


We always try to find interesting watches that many collectors seek. Here is another great example. This is the Gruen Day-Night. The gold-plated case with signed stainless steel screw-back case and bombe lugs (inwardly curved) measures 33mm and with the naked eye, looks very good without any major scratches or dings. The dials on these watches are very interesting. The apertures at each marker display ‘green’ during the day, then after 12:00 am they turn black. The manual winding Gruen movement was just cleaned and is keeping time perfectly. The band is new Gruen-signed leather.
