This Seam Master is high on my Wish List!!!
As I recently got the Blancpain FF Vintage, I got back from the Service Center my JLC Polaris, or more precisely, the Lecoultre Polaris, I'm hunting badly this SM 300...
Yours is in a very good shape, with a nice patina, as I love them!
Congrats, I'm totally in love wit it!
Best.
