The new Lange 1 is another example that times are strange for watch fans: Patek releases the first in-house chrono but can not repeat the success of the Lemania based one.
With the Lange 1 I fear it will be the same: the first L1 was "based" on a JLC movement.
The new L1 is all, from scratch, a new development and hence "100%" Lange.
Here I would differentiate between both, compared the the Datos, and would choose the new L1.
BTW: that the balance wheel has been put next to the winding crown is a very small detail that shows the quality of engineering and is a big, big teaser for a watch nutt
