Do not spam thread it is genuine watch
Looks like one is gen and the other is clean based on the DAYTONA text colour and font.

Hmm, I certainly don't have good enough eyes then haha. I thought that picture 2 was Clean due to the lighter red text and cold white colour dial.

Nope , gen hands are gen hands … sharp and defined lugs like no rep cant replicate
Thing that I dont like is Clean ss bezel. Of cause it’s better than others but edge is too sharp. Might fit well for some Mark # but not for most ss daytona I’ve seen

Is anyone else having a problem where it doesn't like to change minutes and the chrono hand jitters really bad? All the pics online show them super smooth. Its serviced as well.

If you gonna service it the watchmaker can align , if not, it is on you what you will do
The chrono (big seconds) hand on the rep 4130 movement will always be a bit jittery because the rep movement doesn't use the fancy LIGA chrono seconds wheel, but rather has a standard brass chrono seconds wheel. The LIGA wheel that rolex uses effectively removes any backlash between the chrono seconds wheel and the seconds wheel in the movement when the chrono is engaged. This is because each of the LIGA wheel teeth is a tiny spring that grabs the tooth of the wheel that it's meshed with, and thus doesn't allow any play between the wheels. The play between these two wheels is what causes the chrono hand to appear to stutter when the chrono is engaged.
This is what the gen chronograph seconds wheel looks like:

Thats just it though i am totaly fine with a bit jittery. I have a 7750, I’m used to it.
BUT…
It makes it really annoying to share this problem. because it wont ever be as smooth as gen, thats obvious, but mine is REALLY bad. The ones online all the noobs and cleans are butter smooth at least compared to mine. Mine only ticks about 2 times per second for about 1/3 of the dial travel. When it arrived it had condensation in it as well, so im worried itncould be water damage.
also, the gen 4130’s didn’t always have liga, and they are still very smooth.

It sounds like you might have received a lemon Daytona. It sounds like it should probably be serviced right away by a good local watch smith. And yes, the LIGA parts weren't always there in the gen 4130 movement, but the level of precision and finishing on gen parts is considerably better than the level on the movements from Dandong. But that's also why we don't wait 3 years and pay $17500 to an AD for a watch. And if the stuttering hand really bothers you that much, consider buying the LIGA parts and have the watch smith install them when s/he does the service to solve that condensation problem.

Great article bro. There's also a great video (see below) referenced in the same article in case anyone is curious as to how they make these tiny little parts so perfectly...incredibly brilliant process!
