Both wonderful watches,
and there is no cleaner display of a perpetual calendar than the Moser. I am a big fan of perpetual calendars, and this complication is a must-have for me.
But then there is Lange, and there is the Lange 1 Lumen. I do go back and forth in regard to the value of this watch relative to its high price. But I don't go back and forth in regard to the semi-transparent dial that Lange introduced first on the Zeitwerk Luminous and now on the L1 Lumen--I love this "complication."
I would go for the Lange. You will love the watch on your wrist. It will probably be one of your long-term "keepers," and it does not seem the Moser fits in this category for you. The Lumen has been in very high demand since it was introduced, it is never a bad opportunity to get a limited-edition Lange, and this is one of the best.
Go with your heart, though it is certainly possible your heart is in two places, and it is not a bad idea to get feedback here. Seems the opinions so far here are unanimous--go with the Lumen.
(And I think it will be easier in the future to find another Moser, if it turns out you have made a mistake.)
