What other wristwatch needs a separate key to wind it??!!!! 😮😮😮Reminds me of an old grandfather clock we used to have when I was a kid, and it needed winding with a key every 7 days.
I believe the minute hand of this one jumps every 10 seconds or so ...
One small issue is that the dial is a bit plain, but other than that it is one of my most favorite Langes.
