I got this from a lady whose grandfather inherited the movement. It seems his great-great-grandfather had scrapped the case in the 1920s and kept the movement. So the family in 1980 sent the movement to Switzerland and have them case it in an 18 karat gold case. Obviously the Swiss took the opportunity to pad this job a little. And made an unprecedented gold case that weighs a freaking ton. So in addition to being one of the largest heaviest cases I've ever seen. It also has a lugrin patent. Just kind of a cool watch. Now ?
