A7750 replacement needed, recommendations?

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!

In my experience, it's probably best to have the movement in your watch serviced, over the years I've had three Asian 7750s serviced, one by Domenico and two here in the UK, always best to consult a repair guy about sourcing parts first in case you need them, I recall one of mine needed a spring but luckily the repairer was able to source.

Once repaired, they do seem, in my experience at least, to be quite reliable. If you have the cash I would invest in an ETA 7750, although you're running into serious money that route.
