The first generation of all . . .
. . . cal 60/61/65/90 Pano series watches were distinctive and immediately recognizable, with a strong identity as Glashütte Originals. Here are a few images from Yong some three years ago . . .

. . . from which a visual comparison can be drawn. The most visible changes are a thinner bezel on the second generation model in your images, and the absence of chapter rings in both subdials; less obvious is a slight increase in the dimensions of the case. The net effect is subtle, but noticeable.
Many thanks, Nico. I'm trying to arrange a photo session at a local authorized dealer to photograph the latest models, especially the blue Senator Sixties, which I found striking.
Best,
