Found this Omega Constellation in my grandpa’s things. I googled the serial number and movement and tried to learn what I could. I would love to take it somewhere and get it working. When I pull the crown and turn, the hour hand moves, but the minute hand seems stuck. My main questions are, what kind of place do I take this piece in to get it repaired, and are there any specific questions I should be asking outside of “can you fix this.” Never had a vintage piece like this, and I want to do right by it and my grandpa.
