These are the Langes I own / used to own:
Started off in 2014 with the Lange 1 Soiree (still in my collection):
Then I really lusted after a Lange chronograph after seeing all the sumptuous movement shots on forums such as this, so I got the 2nd gen 1815 chronograph back in 2016:
Sold that one recently as I found it a bit too sterile over time (for lack of a better word).
Then in 2018 I upgraded to the mighty OG Datograph in platinum (still in my collection):
This sums up my Lange journey thus far. Nowhere near as nice as the OPs collection, but lovely pieces nonetheless. Hopefully I will acquire another Lange watch in the (near) future (the Zeitwerk's call is strong).
Cheers,
Pieter
