There are two problems that have been stated. Crown Guard and the movement. Nornally the movement is just rotates but i do know of i couple of dealers that have just a couple left. There was a thread over on RWI, have not looked here, where someone had made one with the correct bridge, but withoout the correct cg,lol. I know these are available too, Angus has them on occasion, so does another dealer that is not on these boards. A gentleman whom i get all my watches from.
