I would go on the Dato, the simple one, not the perpetual.
And will get, with the money I saved, the Langematik perpetual.
Not LEs , but is it that important?
To me, what is important is that the watch is coherent, interesting, a fatal beauty, I don't really care that it is Limited or not.
By the way, the new LE Lange 1 Tourbillon makes echo to another LE Lange 1 Tourbillon, in the early 2000s.
So the Limited is not so limited...

Best,
Nicolas
