After a substantial deliberation process of 5 years, you could not have done better. You hit upon the key point: The Jumbo is not super complicated, it is just super.
The thinness, as you said, makes its own statement on the wrist. There is a reason or reasons this watch has been around for nearly 40 years basically unchanged. I am happy whenever I see someone discover this watch or realize their dream and get one, passing over flashier, more expensive or more complicated watches. It reminds me of the light bulb that went off over my head when I first strapped one on my wrist: oh yes, this is THE watch (As Nicolas says above).
I hope you enjoy it for the rest of your life.
