This is a 2006 Lange and Sohne Grande Lange 1 that I purchased new in 2006 from an AD in Italy.
I had first seen this watch on a trip to Berlin the prior year. I was walking past an AD there when I saw it in the window and fell in love with it. In fact, over a 3 day period I went back to that AD to look and try it on 3 times and all I could think about on that vacation with my family was this darn watch! I did not buy it and returned to the US depressed!
The very next year while on another vacation in Italy, I noticed the same watch in an AD's window. I stopped, went in, told him I wanted to buy the watch, and walked out with it within 30 minutes. I have loved looking at and wearing it ever since! What superb simplicity, design, and workmanship.
I hope you enjoy the photos!
