[QC] How Accurate should a Super Rep be?

[CeterisParibus]

Hi everyone,

I received a QC from Jtime, and even if i'm a total noob, i'm not here to ask you if it's good or not, and what to check. I'll handle it by myself.

I only have one question : what to expect in terms of accuracy ?

I saw on the QC +6s/day, and it seems to be very high for a high end replica :


At this price, i expect something amazing and i'm not impressed by this poor accuracy, my gen Seiko 5 is better. But may be i'm wrong ?

Seems ok to me, but your call Sir, it's your money at the end of the day hwell:

Regardless, perhaps with a service/regulation a watchmaker could theoretically get it closer to zero, its whether that additional cost is worth it?

But I would be happy with +6s :thumbsup:

Hi,
COSC watches are around -4/+6 s/day. So I don't see the problem... You are lucky to have a better accuracy with a Seiko 5 because it could be worse.

 

[CeterisParibus]

I ordered a Daytona from Jtime which is +4/d.

I don't expect the genuine +/2s but 6 seems excessive, no ?

And my 200$ Seiko is not a masterpiece, they are all +5s max guaranteed

How important is 0-10 sec/day really, when we dont know if it will last for a 10 days or 10 years.

I personally dont care. Just check with your smartphone once a week and set it 1 minute back or forward and you wont miss anything important

I demand 1:1 accuracy , better than gen. Just because !

The result given by Jtime must be for one position. If you make a mean of all the positions the watch will take during 24 hours, I think it will be better. For example : 12 hours at -4s/day and 12 hours at +5s/day gives +0,5 s/day. It is simple to think like this but I can't imagine Jtime makes all the tests like the COCS

What does someone sacrifice when they decide to buy a knockoff replica as opposed to a genuine version of a watch?

Just get it service once your have received it

+6s on the timegrapher could mean zero on the wrist because of temperature, mostly vertical orientation on the wrist versus horizontal orientation on the timegrapher, fully wound on the wrist versus ??? on the timegrapher, how do you position it at night off the wrist, etc ....

the QC timegrapher result will give you a general orientation whether something is severely wrong or not but they don't tell you shit about how accurate it will be on the wrist

if your Seiko gives you a better result you simply lucked out

so to answer your question, +6s is fine provided amplitude, beat error and graph are ok too

Sorry, i wasn't born "Best 1:1 QC analyst" as it seems to be for you.

 

[ugalord]

After shipping it could be -4 or +10. Timegrapher results are valid for the moment of testing.

I highly doubt that your Seiko has "better" values. As already mentioned above there is no ONE accuracy value. It depends on the position (tilt and shift), the temperature and how much the watch is wound up. If you have problems with this values simply buy a AAA-Rep with a quartz movement - they have dream results better than every Gen-Rolex ;-)

+1

If on a timegrapher it is +2 wearing it might be +15 daily

Poor accuracy? It’s close to a Chronometer grade ETA. It’s 2 sec outside the spec of a genuine Tudor and only 4 outside of SCOC. The movement in your Seiko is rated at -20/+40 s/d so IF it’s better then it’s only by complete fluke.

Yes :thumbsup: and there is no need to wind it every 2 days ! I wonder why we buy these heavy and inaccurate Rolex

Gen swiss cosc spec is +6sec.
So +6sec on a rep is fantastic.

 

[Art Tic]

I doubt your new watch will arrive with +6s/d. It will be worse or may be better if you are lucky. I have yet to receive a watch from TD that runs same as shown in TD's QC timegrapher pic. The vibration/condition during transit do not make a mechanical watch more accurate.

Thats the half of the truth ;-)

COSC has also standards for the variation of the rates for different positions and temperatures and the rate stability and the influence of mechanical shocks. I think it is not very likely that any A-Movement will pass all the necessary tests for COSC ;-)
