... with Mr. Bobe.
1. Now that the design proportion of the dial is the same, there are now Lange 1 large and Lange 1 small.
2. Such single barrel technology must be adapted to Lange 1, although it was denied. So, the famous "Doppelfederhaus" print will be gone and eventually Lange 1 and Grand Lange 1 will be the same watch with the difference of just the size.
3. We all like or agree with the new dial design, but were afraid the current Lange 1 will be terminated due to "bigger the better" trend......
I agree that the in-house hair spring will make a bit of a difference. But "double barrel" and that "thickness vs size" were the "trademark" of THE Lange 1, and I do not like the new one (I didn't like the old one, either, anyway), sorry to say. Yes, YMMV. But no one in the room preferred the bigger Lange 1, FWIW. Maybe Japanese have smaller wrists 
Thanks for the report, SJX!
