So, I decided to stay with the 1815 chrono instead of trading it for the Lange 1 blk. dial, and Ive got to say I am really happy with my decision. Here are some pics of my 1815 chrono that I couldnt let go of...

I want to thank everyone on the Lange forum for all of your wonderful insight. Some of the best moves in life are the ones we never make.
Sincerely,
Scott
