This Patek seems an excellent value for money for those who can't or don't want to pay for the expensive MBK (>450 USD) or chinese copy of it (>300USD).
Asian movements are usually reliable, they represent a big part of my collection and have never shown to be more problematic than the swiss ones, honestly. I have only one year and 3 monthes overview however. The Miyota 8215 is even excellent IMO, but I have no idea what's in this one.
I'd be interested on how's the bracelet. A keypoint on cheaper reps.
I have seen similar ones on cqout, but with the advantage of TTK's one that they seem to have a better crown, or better said "crownguard", sorry if I'm not clear enough. The movement on TTK's version also seems nicer, I mean from the aesthetics point of view (golden colour).
The display caseback is also a nice option.
The rotor seems engraved ? (no stickers ?)
Personally I would go for it if I was sure the bracelet is not rubbish.
But before, make sure you're ready for the rep business...
