Polonus, can't thank you enough for this.
Well, I was at an AD a few days ago and played with the gen 389 for about two hours, and man was I impressed!
Impressed with the quality of the REP, just to be clear
Got the ZFac P series (latest "ZP9000" 7750) from Angus last November >> small review
here.
The weight, construction, bezel knurling, position, the date font and even the slightly rounded pearl looked absurdly close to me.
Bezel on the GEN felt exactly the same 1-2mm REP-loose when applying strength to rotate it.
Only things noticeable after starring at the picture I took were the 12 and 6 markers, that indeed are a bit thinner on the GEN.
The lume on the hands look glossier on the GEN and its date font seems a bit bolder. Plus the GEN accordion strap feels way softer than REP.
The 15/30/45 studs' font is slightly thinner on the GEN.
Due to obvious reasons I only snapped one picture, then I cropped and did the "side by side" below.
Please, excuse the lightning conditions and smudges.
GEN on the right.
