I hear what you are saying but personally what I find appealing about GO in pref to the say Lange is her classic styling ala 1845, Senator Chrono, PanoGraph, PanoReserve and of course the very utilitarian and classic Navigotor Perp Calender
The newer c100 watches, at least from what I have seen is a departure from this to a if I may, more mannered Baroque [as in more decorative] styling.
This moves GO to a more niche market, and I am sure there will be happy watch lovers who would subscribe to this new set of esthetics, but perhaps not what I would associate with GO
Still the c100 appears to be a better or at least finer looking movement to the c39. For this I laud Dr Muller and the GO team
But yes I do concede trying to bring out new designs are fraught with danger
FYI I am thus enamoured with the c49 [or c42 for the Karee series] I am very seriously considering buying a used but in mint condition Karee 1845 [Roman dial with lunar and power reserve]
Here's an image of her
