Omega Constellation chronograph, day-date display model for sale. Only the watch itself and the box (in poor condition) are included. The wrist size is about 15.5 cm, and there are no extra links. After taking photos with the case back open, I couldn't find a closing machine, so I had a nearby shop close it for me. At that time, they said the gasket (rubber packing) was deteriorated and closed more loosely than usual. It functions normally and won't come off with regular use, but it needs to be replaced. The price remains the same, and the listing is resumed.
