      Hi from down here. Been such a long time since I have been on the forum. Getting back into the watch hobby again now that I have a bit more time on my hands (terrible pun intended).

      I picked up my Omega PO which needed regulating as it was running about +17 and with it came the print out of the Witschi timegrapher. I didn’t actually see it in the receipt papers until I got home. I didn’t think the results were anything to be too proud of so I assumed it was left by mistake. Now I could be wrong, but for an Omega co-axiel 2500 which is COSC rated I thought an average of +009 (is that 9 seconds) wasn’t too special. But maybe I am reading the info wrong as I just got my own ACE Timer and learning how to read the beats and rate now. Curious to know what you guys might make of the printout reading? My gut instinct is to open the back and regulate it myself but as the co-axiel doesn’t have a regulator and I don’t have the confidence to mess around with the balance timing screws I just may have to return it to be worked on again.

      Appreciate your views. :)

        What stands out for me is the rather large difference between stem up and stem down.
        I don’t see the same “range” of difference in the other positional “opposites” ..IE Dial up- Dial down, etc.
        I would take it back I think

        Best

          Thanks, Randy. I have measured its rate against a computer stop watch over the last 24 hours and it has measured a +6 and that has been while wearing it for the full 24 hours in just about all positions. I just think the amplitudes looks all over the place, but I am far from knowledgeable. Today on my ACE timer it looks like this:

          Dial up

          Dial down

            It has been pointed out to me that these cheaper machines will not give accurate results for a co-axial watch with regards to the balance amplitude. “The co-axial requires special programming for the specific sequence of sounds that this escapement makes” Good to know. Oh well, a very interesting learning curve for me.

              What do you guys make of the second print out? Much better or marginally better than the first?
