"Most complete G.O. timepiece" hits the nail on the head. There may be more glamorous designs like the Pano line (especially the PanoInverse) or more complex ones. But if you ask the people at G.O. They will not hesitate to tell you that the Chronometer is the DNA of the brand.
This is easily perceived once one puts it on his wrist. And this is the thing that IMHO the blue dialed, more fashionable, version is lacking. The blue one has a great dial but to me it does not convey this feeling of having an encounter with the history and the present of watchmaking that the white dialled versions give.
A great shot of one of the greatest watches I know about.
Best,
Martin
