While back I bought this sucker and it was serviced in 2013 and it is in beautiful condition, movement was really quiet. Today it stopped working! I noticed the rotor makes terrible scraping noise and hands aren’t moving, also the chrono doesn’t work. Tomorrow i’ll take it to a watchsmith and hope that it doesn’t require full service. My quick Google search told that it’s common for 7750 rotors to come loose because of their weight. Does some of you had the same issue?
