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 back cover open, I couldn't find a closing machine, so I had it closed at a nearby shop. At that time, I was told that the gasket (rubber packing) had deteriorated and was closed more loosely than usual. There are no problems with normal use, and it won't come off if shaken, but it needs to be replaced, so the price remains the same for the re-listing.
