The solution to a tuning fork movement losing time may NOT be a question of simply moving the regulators. If the watch loses a LOT, then moving the regulators will not bring the watch to time. You said you had the tuning fork replaced. That job is best delegated to someone who is familiar with these movements. If you had someone do the job for you, that person should have returned the watch to you, adjusted properly and regulated for accuracy. If the watch is losing say, minutes in a day, it likely requires re-phasing. Once it is properly phased, only then can the regulators bring the watch to time. Do you have any warranty from whoever did the job? A worst case scenario might require replacement of the index wheel.
