Nico,
The current Mrs MTF and I collected A. Lange & Sohne watches....not a drawer-ful like some people here
...but enough to appreciate the different aesthetic of the 1815 Collection compared to the Richard Lange line or the seminal Lange 1 range.
The 1815 Collection exude an air of quiet functionality. There is no extremis nor excess in the form derived from function. The big hole on the dial for the tourbillon cage is precisely that... a hole for the cage. Nothing more. Nothing less. I feel calm when looking at the dial. It points me to the functional sector..... the time display.
I like the Richard Lange too.....after all, I got one as my "Life" watch after lung surgery because it has no date display. I can live the rest of my life not counting the days but that is a different feeling of nothingness.
Regards,
MTF
