Ordered a 512 and 569 from Ryan and got Timegrapher results

[DR3M3L]

Both watches were +9 seconds a day with .6ms error
I thought the .6ms was high for both and told them that, and consequently they instead of answering my question just approved the qc pics..... which i didn't approve myself

People on the forum love ryan, I'm surprised he would ok QC pics like that..... what should I do? Allow the watches to ship, or ask them to be switched out

 

[theballer]

Isn't .6ms high? Especially one for to a movement without a selfwinding rotor attached...

 

[Thrasher]

I think 9 sec is ok, I have seen a couple of my watches gain a minute in a couple days, So I messed with the regulator and got them a lot better. I would not worry, is not COSC like 5 sec.

What movements are these in particular ?

What movements are these in particular ?

They are an Asian 23J and an A7750

I agree with Thrasher on the 9 seconds thing.

Ok as far as the beat error, most watchsmiths i have talked to say .8ms is the highest they will accept.
Im not a watchsmith but i do have a Timgrapher, so i do have a little experience , and i do my own timing and adjustments.

I always try to get my b/e down to 0 or at least .1 ms.........this is on my swiss units.
But to be honest, alot of our rep movements WILL NOT tune much finer than .5ms .....so you are a LITTLE over on that aspect.

But heres the kicker.....i have one 21j that i cannot get the beat error down past 1.4ms...... but that watch runs +10 seconds a day all the time. The best i can get it, but it is consistant

So you think I'll be safe to go ahead and accept it?

 

[Raddave]

So you think I'll be safe to go ahead and accept it?

I would, id feel safe with those numbers.......The traces looked OK ?



Good trace:

(ps look at the b/e)



Bad Trace:

see the center of the screen, the random dots is bad

Hi, imho You should accept it.
3. Beat Error - how equal each swing of the balance wheel oscillation is.

• Excellent : 0.0 - 0.5 milliseconds
• Acceptable : 0.6 - 1 milliseconds

My layman opinion is this one: the main reason for the timegrapher pics in the qc-process is to show that the watch runs; results will depend on the position, temperature and if it´s just been given 2 or 3 winds to make it run or if it´s fully wound; the same goes for the +9s a day, in reality once the watch has been used for 2 months and "run-in" the result will be different.
If everything was ok visually it´s fine, don´t worry.

 

[theballer]

WOW! never once did i even notice the trace.....

 

[theballer]

how does that one look, its wobbly the entire way through, never any solid slopes

we cant see your pic you need to post it to an image host like IMGUR and post the link....your posting it from your email so we cant see it

 

[Tickleshoes]

I was just impressed that I got a timing QC pic in the first place! Is this really 0.0 though?

 

[Raddave]

And what Daywatch says is correct......

The biggest probblems ive seen with a bad beat error is if the watch runs down, it wont just start up with winding, you might need to shake it a bit, and im talking about a 3.5 or more b/e here.....

 

[theballer]

How about now?

 

[theballer]

we cant see your pic you need to post it to an image host like IMGUR and post the link....your posting it from your email so we cant see it

I posted the pic again, hope you can see it

 

[Raddave]

Yeah i can see it now........I would have no problem accepting that !

 

[Raddave]

Do you have the pic for the 7750 ?

 

[theballer]

Do you have the pic for the 7750 ?

Sure do brotha here it is

 

[Raddave]

That one looks good to me too.

Reason i asked for it was cause you said that they both had the same b/e and the same 9sec timing and i was afraid that the timer was paused for the pic, but i see that is not the case as the BPH is infact different.
