I picked this up last week and it just got here today. I have had this watch on my list now for a couple of years. I thought it had either a Venus cal. 188, or a Valjoux 7733 movement. Now that I have it and have been doing some research. I believe its a Venus Cal. 170. I am sure the crown is not original, but I do like it. Its kind of beefy. So far its running spot on, but I am going to send it out for a cleaning and new seals. I think I am going to leave the case just the way it is. Same with the dial.
