1954 movement in a '57 (L7) case. Nice stainless case and back. I have a feeling the stem on the watch is wrong since it protrudes so far from the case, or the crown is wrong. I don't know. The watch is hard to set turning it forward, it tends to make the crown come undone. It sometimes runs for awhile but not always. The movement needs to be serviced. I was planning on installing a nice working black faced movement into this case as its currently in a non Bulova case. I can't figure out how to remove the crown to remove it from the case however.
