JohnG 41 Posted February 23, 2009 A new easy tell has been spotted on the clone ETAs. The Incabloc Novodiac-style balance wheel jewel seat/retainer has a single slot for the retainer ring, whereas the gen Novodiac seat has three slots... It is often hard to see whether the click wheels have eight holes (clones have four) but this is an easy tell once you know what to look for: Gen: BKLM cites the shape of the Novodiac retainer spring as evidence of the authenticity of the movement, but in fact he is wrong... What makes this movement a gen is the fact that the jewel seat has THREE slots for the installation of the spring... Gen with old (non-Novodiac) Incabloc retainer (clones never used this retainer spring) Clone: see SINGLE slot - this is never seen on genuine Novodiac seats... BKLM calls this one a clone because of the retainer spring shape - but below I posted a pic of Novodiac retainers - their shape does vary and this is not proof - the proof is in the number of slots the the jewel seat: As can be seen from this shot from Otto Frei's website, the Novodiac can be both "more curvy" or "less curvy"...

NFleischer 4,355 Posted February 25, 2009 thanx alot john. i also read that the big silver wheel(whatever you call it) on a gen tends to be brushed finish whereas the clones tend to be shiney. chris fro eurotimez posted a thread about that last year @ RWG2 Share this post Link to post Share on other sites
JohnG 41 Posted February 25, 2009 thanx alot john. i also read that the big silver wheel(whatever you call it) on a gen tends to be brushed finishwhereas the clones tend to be shiney. chris fro eurotimez posted a thread about that last year @ RWG2 Yes he did post that but something Ziggy posted once seem to cast doubt on that as an indicator. I don't remember what he said exactly but he didn't seem convinced that was a reliable indicator... Ziggy did however mention the novodiac (or Kif in that case) seat and at the time I didn't understand what he was talking about... Share this post Link to post Share on other sites

othniel888 0 Posted July 28, 2011 (edited) Anybody else notice that the 3rd photo used to show the "single slot" says 2824-2 on the movement (at about 8 o'clock position). (The second photo says 2824-2 on the rotor as well) I don't know if that matters or not????? Someone please enlighten us further on this point. Is the 2824-2 the version before the 2836 or ???? I'm still a bit of a newbie on these finer details. Thanks!!! Edited July 28, 2011 by othniel888 Share this post Link to post Share on other sites
wat44 0 Posted July 28, 2011 this info is probably out of date - several people with a keen eye have been not able to tell newer clones from gen Share this post Link to post Share on other sites
