Hi all, been here awhile but this might be my first post (I lurk).

My prized omega planet ocean has kicked the bucket and I'm looking for a replacement movement. I think the watch is this one, although when I bought it was called 'Ultimate Edition' so I'm not 100% sure it's the same; Seamaster Planet Ocean Chrono 45mm SS Black Dial Orange Markers on SS Bracelet A7750

Anyhoo, any recommendations on where I should buy a replacement asian 7750 movement? I know eBay is an option but then I wouldn't where the movement originated. I don't think all A7750s are created equal and the early ones had quite a few problems as I'm sure you're aware.

TIA!
