I do wonder how they managed to get the hands to appear to be "floating", without any kind of support! How do they keep on time - the stem doesn't seem to be attached to any kind of rotor?
If it is like other floating watches, I think the sapphire actually turns and the hands are just affixed to that. I read about them a few years ago as the history is neat on these kinds of watches.
I believe it is sapphire crystal disc that rotate which give the appearance of floating hands. Cartier has been making mystery clock versions for more than 100 years.
I find the blue and black dials on Lange 1s are a bit lifeless. I greatly prefer the Lange 1s with silver dials.
Interesting to see your perspective about more modestly sized watches has changed. I look forward to seeing how that affects your future purchases.
