      Guys I just received a Master model cleaner and I am going to have to completely rewire the machine. I would like to convert it to a mastermatic be replacing the forward and reverse switch with a time relay circuit. Has anyone done this and if so any guidance would amazing. Thanks.

      Hello
      I measured my Omega Caliber 1120 through an timegrapher app. (Dial Up, full wind)
      I know the app is not very accurate.

      I checked about +100s/d difference and sharply tilted graph .
      The odd thing is that the bottom part of the graph is not printed every 100+- seconds.(red-colored circle)
      Is this a feature of the timegrapher, or does it indicate abnormal state of movement component?
       
      Thank you for the comments.

      A vintage Elgin 15/0, Gr 559.  I took it down, cleaned and lubricated it and it is gaining 15 minutes/24 hours.  I have looked at the HS, it appears to be perfect, clean, flat, not magnetized (de-magged the movement X 3 already), and in position between the regulator pins.  Not hung on the center wheel.  Correct mainspring, and balance is not knocking.    I do not remember amplitude, but IIRC, it was above 22 which is O.K. by me with the movement.  Please give me some ideas as to how to correct this.  It doesn't seem like there are enough timing washers in the world to slow this down!
       
      Thanks,

      Hi, my name is Ross. I am a rookie watch enthusiast and I am really puzzled here.
      Could someone explain to me what kind of a problem am I facing with my timegrapher?
      I do two sets of measurements with the same watch (1 day or 6 days apart) and receive vastly different results - to the point of being completely different from what I observe in real life. 
      For example, my timegrapher shows that my watch is running fast (or ahead of time), while in real life I observe that it runs 7 seconds per day behind. I even recorded a video about it so you could see it for yourself: https://youtu.be/mhGzf6aLMlY
      How should I interpret that? Am I doing anything wrong?

      Hello. 
      I am working on a vtg. Citizen cal.7520 automatic movement.
      I have put the watch on the timegrapher 
      The graph looks OK but the beat error shows 9.9ms. I presumed that beat error should be around 1.0~2.0 given the shape of the graph.
      Is the beat error actually bad or the timegrapher is wrong??
      Thank you!
