I wound it up and it took right off. Please assume it will need to be professionally cleaned and serviced. I did not check for time accuracy. For offer is the watch movement pictured. Unless otherwise stated above, It is for parts/repair only. If it has a stem, I wind it up and see if it ticks. If it does not tick, I have a can of compressed air and I GENTLY blow on the balance wheel to see if it rocks as it should. If I do not state that the watch ticks or the balance wheel rocks as it should above, then it does not. All the movements I will be listing the next few days were taken from cases that were scrapped. I have no history on any of them and none were tested beyond what was mentioned above. I offer no guarantees on condition or functionality. Pics are accurate and unaltered. What you see in the pics, will be exactly what you receive. Less any size reference devices of course.
