Is -13s/d acceptable? I just received qc pics and am surprised to see my watch will be 13s slow everyday.

Acceptable seconds per day loss/gain

what kind of movement, what position, how much winding, what are the other positions?
The answer is yes, no, maybe.

CLS answered this best, I think it's acceptable, but a lot of factors can cause a movement to vary in accuracy.

I heard that gain is better than slowing...(??)
But 13 sec is ok for a unserviced asian standard automatic mvmt I think. Good is +-5sec I would say....

that's quite a curve and some odd beats. could be ambient noise or reverberation in the case causing the beats. The curve could be from just starting the timegrapher. It also could be something wrong with the watch. There shouldn't be a curve, I would ask to see another timegrapher shot.
13 sec / day is fine BTW if that's it.
No, running slow is the same as running fast (if it's within reason,) but for some reason people are happier when their watches run fast.

As I recall, COSC allows for -6/+8 so within 13 for an A7750 is pretty good.
I mean, after fours days you will still not be even one minute late for work.

Gaining or losing is ok but its not good though when you adjusted the movement all the way +or- and its still gaining or losing that's when you have a problem and its time for a service

I would like my automatic in the "plus" side when new, up to 15 sec per day, because they tend to SLOW as they age .... Just my opinion, though!:cheers:

I change watch everyday - and when I set it, it's lucky tobe within a minute of true time to begin with!

I'd be much more interested in the amplitude. That's the most important number. The beat rate can be adjusted, not so much on the amplitude. Strange how that's been cut off.
I agree with changing watches daily
But I disagree with want to be accurate? buy a seiko!
You want to be accurate? Use your smartphone!
That way you can still wear your rep...
