Today when I visited my AD, they gave me this DVD as a present. It appears that this DVD was made in cooperation with A. Lange & Sohne and A. Lange & Sohne Japan. The video was video was very educational for me, and enjoyed watching the process behind making the Lange 1 to its first "heartbeat". I'm planning on buying a Lange 1 at the end of the month, but after watching the video it made me want to go back my AD tomorrow...I think thats why they gave me the DVD for free!! LoL The DVD itself is black and is embossed with RL dial. I wanted to take picture but it was hard to take with reflection. Please find below picture an English translation of DVD contents
