Thgis is a very uncommon WITTNAUER (by LONGINES)bezel set alarm watch from the 1960’s. The 36mm. 10k. gold filled three piece case is very cool. To set the alarm, turn the bezel counter-clockwise. The turning of the bezel actually winds the alarm as well. This alarm produces a unique “gong” sound as well! The textured dial with very unique stylized numerals is all original (including the hands) and is very cool. The unique 10WA manual winding movement was just cleaned and working perfectly.
