Mother Pearl Surface. Quartz. Oct, 2017 - changed new battery and finished a full checkup in Omega shop. 60%-70% New, some scratches but can bring to Omega shop for polishing as I did one time, and looks very shiny after polishing. With extra parts for adjusting the length. Full set packing, including the outer box, wooden box for the watch, watch bag, warranty cards, user menu, maintenance record/invoice. Only no receipt because it was a gift.
