I bet you are craving for a G.O. Chronometer. And I know the feeling well. Took me six years of dreaming until a stroke of luck paved the way.
During that time I did not allow me to purchase any other G.O. and no other naval chronometer like watch. There was always The One...
I wonder if your interest in the white dialled, blue handed Senator Observer is somehow linked to the Chronometer ;-)
Best, Martin
