Seiko 7s36 movement

[icebeak]

I at new at mechanical watches. My watch seems to be running fine, but when I wind it up fully, this is what shows up on the timegrapher. Does anyone know what the problem is? 

Thank you.

Did a demagnetization: timegraph after demagnetization:

how did you wind it up fully? Then after getting it fully wound did you put it instantly on the timing machine?

I am just guessing that it is pretty fully wound, by looking at the amplitudes. I have been observing this watch on the timegrapher for a while. Yes, I put it instantly on the timing machine.

normally when timing a fully wound up watch especially if you just wound it up you let it settle down for 15 minutes to an hour. A lot of it depends upon the watch. The problem with this Seiko is their tech sheet doesn't tell you how many times you have to shake it to wind it up. then it's nice if you time in more than one position I'm guessing you had either dial down or dial up? so dial-up and dial down will be nice they both should be the same and a wristwatch one crown position like crown down as that's a common position for wristwatch. sometimes problems only show up in one position which is why multiple positions are nice.

then one of the minor downfalls of the Chinese machine is it would be nice to be able to here the watch? The reason is it be really interesting to know what the watch sounded like when it was producing that strange waveforms?

so after you'd demagnetized and the problem went away if you repeat what you did to do this the first time does the problem come back?

then interpreting the timing machine? It's kind of like reading a crystal ball at times while there are guides out there waveforms are not always exactly clear on what they're trying to show it to us. For instance if your watch was running fast when it did its bizarre thing I would refer you to the two videos below. The first one explains about the condition and the second video he has a newer timing machine so you can visually see it on the newer machine and the real audio as that machine has audio output not beeping like the Chinese.

what makes you waveform interesting is the line is relatively straight except when there's a problem and the numbers indicate the watches going slow?

Thanks for taking the time to answer. After I demagnetized, the problem disappeared and then came back after about 15 minutes. I then adjusted the regulator pins by turning them slightly. This time the problem went away for good.
