Gorgeous examples. I have the rose gold Walter Lange jumping seconds and it is one of my favorites. The man himself was partial to yellow gold of course ...
implying luck goes up and down...so for this case, level of interest of people's taste changes through time. Like you said, let see...if Rolex will have more YG releases this year like they did with the YG TT SD.
I too remain curious as to whether the trend will have staying power. As for colored dials, I'm all for the recent emergence of green and red (think IWC Portuguieser Chrono and Automatic, the last from Czapek), and really hope to see more salmon and brown...
Yellow gold is and was the metal of choice for any high end watch. Regardless in the West or in the East particullarly. RG and WG are actually niche products and hence the premium. I love yellow gold!
I know there are some models with the hinge back and his signature but not the inscriptions. ALS probably should start a museum for all their important watches. Thank you for the surprises of Lange you always bring to the table
