Just got my PAM104 rep from Sead, and I can confirm as a gen owner of the watch that the rep is easily bordering on super-rep status.
My CG was loose also, must be a factory thing, haha. Other than that so far the time is running on target, but we'll see after a few days if the +2 minutes thing shows up.
In comparing the gen to the rep side by side the only things that are noticeably off are the thickness of the white "PANERAI LUMINOR" lettering (bit bolder/thicker on the rep), and the edge of the cyclops having a ring around it (not an actual ring, but a visible edge on the crystal which the gen doesn't have, it's more seamless).
Other than that, and a few spacing/font things on the caseback it's really impressive. Funny enough the lume is actually better on the rep, go figure.
Put both of them on a gram scale and they came back at 124.5 and 124.0, which amazes me, on the wrist they feel absolutely identical.
Very impressed!
