I purchased a Muhle 'Terrasport II'. I received a very nice Muhle. But the warranty card and tag model number don't match what is on the back of the watch. I've
tried to look up online and such. Box/tag/card say M1-37-37-LB. What is on the back of the case is M1-37-40.
Just trying to figure it all out. Ideally I was shooting for a watch with matching box and papers.
