Timegrapher help with miyota 8215

[avrahamk1]

Hey I just received this QC pic from Sora, Shinewatch and I'd like to hear another opinion on this one.

This is the picture:

As we all know the 8215 stutter, now I do take this on my mind but doesn't the graph seems too weird? There are 2 places where it says +9 and +10 sec/day and the overall graph says -4.
I asked Sora about it and she said it doesn't stutter, I do believe her but I'd like to hear more opinions anyway.

Thanks guys

This Pic shows an Timegraph Pic where the Timegraph Run Maximal 10 Seconds... You can see on the line that it doesn´t goes full from left to the right...

So i wouldn´t not worrie too much about the newer Chinese Movements... The most of them Runs all very good...

So the Movement needs Defenitley an Adjust... Because an Beat Error of 1.0ms isn´t sooooo nice...

The other Point is that the Angle of the Microphone isn´t right... It´s not positioned at 52° maybe Sorra didn´t Power up the Watch Complete...

I am sure if he Power up the Watch full and let them Run an Minute at 52° the Movement will run stable... Maybe it need an Adjust as i said...

But nothing to worrie anout... i would say...

What do you mean by adjust the movement?

Nothing much to worry, i think what Zocker mean is the lift angle which is not shown on this timegrapher, amplitude of 274 is good. As for the rest, don't really have to take it too seriously because imo to get an accurate reading on time timegrapher, the movement have to be test for quite a bit of time and in different position, not just a few sec on it.

I would gladly accept it if it is for me.

Isn't the 1ms should make me worry?

Just got my omega 300 master co-axial from sora this week with similar timegrapher specs and it's a champ, with no stutter either. Tho I haven't checked the accuracy on the wrist.

More than glad to hear that! Hope mine would be like it as well.

This might sound like a stupid question but is there a difference between the Miyota 8205 movement that a lot of the TDs are claiming is in the Planet Ocean and Seamasters and the 8215. Or is '8205' just a typo?

Ive been trying to do my own research but came up with nothing thought I could ask.

The beat error is way off, 1 ms is too much. Should be 0,5 or better less, I regulated my Miyota down to 0,0 in dial down and up. 274 degrees for a non fully wound movement is ok. It is not so easy to regulate the movement thru the deco cage that hides the movement.

Well.. I guess it's a bit late to say that. I already accepeted it. I'll update you guys how it runs when I'll receive it.

I've been trying to find out the difference between the 8205 / 8215 for a few days, seeing as I want to buy an Aqua Terra 150M which usually come with Miyota either of these two. The info I've gotten has ranged from "not much" to "it's more expensive and it has 25j". I guess this spec sheet settles it: Both are basically the same, both have 21j, except the 8205 also has a day feature. So being the noob that I am (and I might be completely wrong here), I have to ask, if the watch in question doesn't have a day window on it (i.e. some Aqua Terra 150M's), yet the makers use a day-date movement, wouldn't this be unnecessary "strain" on the movement, given there is no day window and you're simply better off without it?

I think the spec sheet is an eye opener as it shows what the correct lift angle should be set for, which is 49 degrees . Lift angle has a direct effect on amplitude. And accuracy of -20 to +40 sec a day. The accuracy specs are from a full wind with the watch tested between 10 - 60 minutes

I pretty sure the lift angle affects the amplitude, but not the accuracy (rate) or the beat error.

IMO i wouldnt accept that watch in the OP, and would ask Sora to take another proper testing.

Wow this is pretty old topic! lol
Even my review of it got a little dusty:

Keeps perfect time though!

Glad it worked out for you. But what's so WOW about it?

The discussion of how to properly read and interpret a timegrapher reading is always timely. Especially the importance of knowing what a movt. lift angle should be for setting up the timegrapher before the test.

It probably would be a good idea for you to read and learn about how to do it so you could make the call yourself to OK a rep or asking for another from a TD. just as an FYI, the members that know how to read a timegrapher result, said the length of the test wasn't long enough to judge the rep by.
