who explained 5650 to a collector who did not really understand the watch. Hearing the watchmakers explanation using words like "revolutionary", etc., I only regret that I did not try to get two. Seriously, I wore the watch last night on the dinner when one of the guests asked "what's special about that?"
I knew the details of my 5650 but the most important thing is that it's a fantastic watch to wear.
Best, Kari
