The eta 7753 is a very nice movement. However do not over wind these movements, when this one arrived it worked fine. I put 30 winds with the crown. Ran great the next morning I figured I would put a few winds to top off the mainspring. Well 4 turns of the crown the reversing wheel let go. And the rotor was off and spinning. I took the watch to the watchmaker I deal with and had him replace the reversing wheel along with a full service. I can't complain the watch is keeping time as it was prior to service -2 seconds per day on the wrist. I am not going to complain about that. Actually I'm happy with that.
