VDO watch

My personal item is a clock from my Grandpa. He inherited it to my dad and my dad inherited it to me. The clock consists of 585 gold. My Grandpa got that watch from his employer VDO to a 25^th years belonging to his company. In the past the watch had a stretch metal bracelet. The clockwork is works with quartz blocks. On the backside is a dedication engraved there stand: “25 Jahre im Hause VDO” (25 years in the house of VDO).
