I have a movement A 451-050 H. 114cm/60 which has recently been dissembled, cleaned and lubricated.
The clock needed to be regulated since it was not running at the correct rate
The clock is level and in beat. I set up the microset using the optical sensor and adjusted the pendulum to a rate of 3600 beats per hour
Came back the next day and the clock had lost around 3 minutes. I rechecked the rate and it was still 3600
What's going on
