I have one of these on its way to me, great pics.
All QC picture I've seen with the new 8500 clone shows amplitude around 250. Is this a problem or is it normal?
Edit: is 0.2 beat error OK?
I mentioned this a few posts back, but my spectre 8400 will easily be over 330* amp at full wind on my personal timegrapher, the qc pics did not have timegrapher pic so I cant comment on that. Regardless, the movement design is able to provide well over 300*s of amp if its running well. Hope that helps.
Funnily enough I also recently noticed the "clicking pins" effect, I'm pretty sure it was not there in the beginning but came on only recently when I switched to the bracelet and then back to the Nato
By the way, can you please measure the inner steel bezel in yours?
Thanks for your response. As you already probably know, the amplitude 330 is also not a good thing. The ideal is in between 275-310.
By the way, as Swerepguy already mentioned that he has seen many QC pictures that show a low amplitude of 250 on this VSF 8400 clone movement.
I also noticed that a low amplitude around 250 degree for this particular VSF 8400 clone (no date) movement too by seeing pictures from some other members' posts.
So, I would like to hear what other members think.
Could anyone who purchased please remember what the amplitude was at the QC testing? Thank you

Ideal amplitude is as high as the movement will allow without overbanking the balance, mine has never overbanked so I'm golden, runs great, thanks.
That is good. High amplitude without overbanking. Your are lucky.
By the way, do you think it is better to reject the watch which has a low amplitude around 250 ? (if the other factors are fine though).

Mine about 280, fully wind is 310,if you friendly with TD, try ask 2 QC picture for timegrapher, not fully wind+ fully wind.
Wow, never paid much attention to amplitude, now reading this I realize that I've received watches in the range as low as 220-250 (My VSF spectre was 221). They keep time ok, never losing or gaining more than 7 secs a day. Should I service until they break down? Or should I do something right away

On your QC pics or tested at a watch maker fully wind?
What amplitude did you QC pics show?
I ran an experiment for 10 days with one of my Aqua terra GMT’s on my winder. It was about 30 seconds off for the 10 days. Good amplitude.
I decided to try comparing 3 watches with the super clone movement. The Spectre with the new movement and 2 GMT’s. I also just received a standard Aqua Terra but it was not part this test.
With all the discussion regarding QC’s with lower amplitude I went back and looked at my QC’s.
I’m a fan of Omegas and of the new movement. The Spectres amplitude was 312 but the AT’s were on the low side.
My TD usually doesn’t wind the watches too much and they’ve always been okay when I give them a good wind.
I decided to end the test after 5 days to check on them.
Total time difference was about a minute between the 3.
I put them on the timegrapher. Rates were -8, +7 and +2.
Amplitudes were all good, between 272 and 284. One was 262. I wound it some and the amplitude went up to 284-289.
I’ll check the fourth one soon but it was good the last time I checked.
I’m very pleased with the accuracy and so far they’ve been running great.
280 amplitude, mine is working very accurate, about +45min/month. I think it is very worth it the first batch.
