Hi buyers!!! You are purchasing a Vintage Omega Constellation 601.0103.0 Dark Blue Dial 36mm Swiss-Made Automatic Men's Watch, which is in good working order. My grandfather owned this beautiful watch. I was going to keep it because it's a full case size, but it's currently sitting in my safe. I want it to go to someone who will love it and use it. It was serviced two years ago and is in good shape. Please follow me, I will add more listings every week...Thanks
