The DPT Lumen Honey Gold is the most magnificent watch / Lange I’ve ever seen.
The blue Datograph is lovely in the metal too - it gave me a bit of an 1815 Chrono vibe for some reason.
Shout out to your 1815 Up / Down though! A simply delightful piece - the favourite of my collection.
You have that and your gen. 1 Dato…so you can return home from the Lange event feeling fantastic: same base calibre, same finishing & provenance (in fact, yours was the OG), and the same name on the dials.
