Neen help, advise. Movements

Hi. I am new in Rolex world. Last month I bought an Explorer II Polar from 2008. Soon after this I made an overhaul in RSC. Because I like to see how my watches going on I also have a timegrapher. Looks like there is something wrong in the movement. Graph seems to have a shadow (attached photo). This shadow is almost not there if I set a maximum signal value on a timegrapher. The lowest signal value the more dots appeared.
My other watches don't have this problem. Always have normal graph on a 50% signal value.

Horizontal amplitude is about 280.
Vertical amplitude is 220 - 240 depend on position.
In the crown up position watch is doing +-0 (this is how I put it during a night). When on wrist in 12h doing +0,5~1s.
Only in 12 o’clock down position it has +5~+6s. Other positions are between 0~2s.

Now I have dilemma what to do. Should I go back to RSC with watch? Because it keeps a good time but the graph is strange. Is it possible that something touch balance spring and it will not last for 5-7 years to the next overhaul?

First photo is dial up
Second photo is 12 o’clock down

That's interesting.
If you watch is +/- 2 seconds per day it is within specification.

I think the best solution may be to telephone Rolex and speak to a watch maker.

Nothing wrong, that extra noise comes from sound resonance inside the case.

sometimes having a timing machine at home can be very beneficial. And sometimes it's like having blood pressure testing equipment at home. "hmm, let's see what my blood pressure is today....holy cow! look at those numbers! am i going to die?!?!?!"

see what i mean?

i agree that there's nothing wrong with your watch. let the watch's performance on your wrist (and power reserve off your wrist) be your guide. Don't be freaked out by what some chinese timing machine (a "Weishi"?? hah!) says. i mean, i have a chinese timing machine at home, too, so this is not me judging someone else. But let's have some perspective.

If you had the tools to take the movement out of the case and put just the movement on that timing machine, you'd see lovely results. But as it is, the machine is struggling to get a consistent signal. nothing to be worried about.
