No trades please. For sale is the Omega Seamaster Planet Ocean 600M 2500D Ref. 2201.51 This is the 1st generation PO you've been looking for. 42 mm Rare cal. 2500D movement! Only a small percentage of the last Planet Ocean’s to come off the line had these before production switched to the second generation 8500. These carry a price premium, but are also much more sought after for a collection. The 2500D was upgraded from the previous 2500C to have a tri-level Co-Axial escapement, instead of the previous bi-level. Omega has continued to use tri-level escapements in the 8500, 8900 and other current movements because of the improved reliability. The movement is running within chronometer spec and shows strong amplitude; see photo. It was fully serviced in August 2022. Water resistance tested to 50m (limits of my equipment). The pictures tell the story, so I will defer to them to see the exact condition. The photos are high resolution and can be opened in a new window at full size that can hide no flaw. This is the cleanest 2500 PO I’ve ever handled. 6 full and 1 half removable bracelet links included (full set).
