Regarding the subtle evolution of the PanoInverse, I have to say that I had been really disappointed by it. Let me explain. GO has only reworked the bezel and nothing else and, for me, it was a true mistake.
With this "evolution", the dial is now not designed for this new bezel. You have a kind of gap between the bezel and the different elements of the dial such as the double swan neck, the writings and so on.
In my opinion, this bad evolution is similar to what Breguet made with the Tradition even if it was worst in this case (a 2mm bigger case with the same dial so they made an angled bezel, a bigger sub dial for the hours and minutes which has obliged Breguet to put the hand of the power reserve on the rim of the sub dial...). For me, a true big mistake just because clients wanted a bigger Tradition 😱☹️
