I had recently purchased a Montblanc GMT Sport. The seller was kind enough to have it serviced for me. My thoughts after wearing it are its a wonderful watch and is definitely worth each cent I have spent on it. I had the opportunity to view the movement inside a couple of times but both the times I could not get a snap of the movements. I can take snaps but I don't have any equipment to open the watch. I shall appreciate if anyone can share pics of the movement.
