OMEGA red cube box for Chrono Quartz 1976-1978

The red OMEGA cube box is very desired. It came along 1976-1978 with the Omega Chrono Quartz watch at the Montreal Olympic games. Not many survived especially in good conditions. The box shows some marks to bottom and a small mark at front bottom part. Apart from that its perfect. Especially the backside which is with this particular  box model the most sensitive part.
