Omega Seamaster Planet Ocean on stainless steel bracelet, prior generation ref. 2201.51 with caliber 2500D movement and 42mm case diameter. The watch is in great condition, 95%, with very light wear marks on the case and bracelet. The inside end piece has a couple of line scratches from strap changes, but not deep or visible when worn. The 2500D movement (evident from both serial number range and a serif on the date wheel "1") is keeping spot on time, well within COSC limits. The dial is black with orange numerals on the 6, 9 and 12 indices. The watch comes with everything shown in the photos, including three red Omega cards (warranty has expired). I do not know if and when it was last serviced but since it has neither the original red dot or a post-service blue dot on the case lid, it has likely been serviced. It is running superbly nonetheless.
