Hello, Mike,....

I think there is at least a bit of misunderstanding.
My impression is, that Minerva/Montblanc's claim was about the combination of the triangular shaped tooth profile (clutch wheel) with a more epicycloidal (or evolvent, or whatever   ) transfer wheel (the more traditional design beeing triangular shaped teeth for both).
In mybook this is not new as it has been done before. Of course I'm speeking about the principle here only (the combination/mating of triangular tooth profile with a more rounded profile).  At least my understanding was along this line, from your post and from what  I've read earlier in Magnus Bosse's article (see also his post aboce with sketches). I'm sure  all the tooth profiles are made to their own specs and their design - but this most likely applys for any movement  manufatcurer.


Furthermore, in fact the developement of tooth profiles is a never ending story - new design aids and manufacturing methods  frequently offer  new ways and possibilities so that this is an important field for improvement. I'm pretty sure this is one major point for almost any movement  manufacturer.
The actual changes and improvements are  hard to comunicate though - which will be one of the reasons  you'll not find a lot of info about this particular detail though.

To me personally the particular subject we're talking about is a good example for many others - but again, that's my personal view only and I'd be happy to learn if I'm wrong. It's one of the problematic parts of the internet IMO (I wouldn't say that it is limited to the internet though as one finds similar happpening to the traditional media as well). One enthusiastic passionate  journalist writes an article about a company - of course the major source is a visit to this company -  many of  the technical details are incredibly interesting and due to their nature even for pro's not that  easy to follow (not to speak about veryfying the information).
At the end you'll most likely find some great and passionate  information, but also some parts which are at least a bit questionable.
Coming back to the subject - in my oppinion the technical  principle was old news and also done before - but  reported  as something special and remarkble....
As a funny sidenote, that more than once I've been surprised to see companies presenting "new developements" which were in fact hundreds of years old - even newly applying patents for well documented more than century old inventions.   In some cases I'm pretty sure that there weren't any malicious  intentions - sometimes it might have been simply good ideas found by different people at very different times (and not knowing of each other).

Sorry for my deviation of the subject -  and I'd be glad for any addition or correction

Best regards
