Tudor Heritage Chrono running fast - why and what to do

[aeroeng1]

My Tudor Heritage Chrono runs steadily at +7s a day, with chrono off. A bit disappointing as I have two other watches with ETA 2824 and they run at +2 or +3s (including Steinhart that costs 10 times less).

I have experimented with leaving watch in different positions over night: crown down, up, crystal down, up, and I always seem to get +7s a day no matter what.

Hope someone can answer this:

1) How come Tudor delivers a watch that is so imprecise out of the box? I would understand if the watch had 10s variation from day to day, but this runs at +7s every day, so the movement must run perfectly. It's like atomic clock, but not regulated :D
Don't they regulate it to +1s or so before it leaves the factory?

2) Do you think Rolex service centre will adjust it for free (1 month since purchase)?

Thanks!!

RSC will regulate it free of charge. After they regulated my THC it ran for many months on end within a few seconds of exact time, with overnight positioning. The 2892 is a great movement.

Fantastic, thanks for quick reply!

Take it in and have it regulated. Great watch.

Tell the watchmaker the time you observe from wearing it

First cannot understand why you state your watch so imprecise its showing consistency which is the most important factor with any mechanical watch.And now showing as you stated 99.99.3% accuracy and no they do not regulate to +1 second.And even if they did regulate it on a machine to +1, it does not mean it will perform exactly the same while on the wrist every day.Many factors effect the movement while on the wrist given the fact that the movement is constantly affected by the earth's gravity, metal expansion and contraction, temperature variations, subtle changes in lubrication,mainspring power-reserve, friction, shocks, and so on.The fact is that no mechanical watch made will keep perfect time, very close yes but perfect no.Your watch is +7 seconds out of 86400 in a day myself would leave it cannot see the point of getting the back off for perhaps 3-4 seconds.Have you ever given your watch a full manual wind say 40 full crown turn clock wise.

Because I can't call +7s "running perfectly on time" ;)
Just don't have this experience from other mechanical watches I have had, all of them ran at +0.5s to +4s, even after years of use. This is my fourth watch with ETA. May be I'm just lucky.
But it's good it's consistent, I'll ask to get it regulated.

An update on this post:
Rolex service centre took it in for a couple of weeks and regulated for free.

Last two months it had been running at 0.3s a day, i.e. 9s a month!
Happy I didn't tolerate 7s a day, thanks everyone for advice.

Thanks for the update and glad you got it regulated! I think its silly to say because a watch runs 99.99x% accurate out of 86,400 seconds each day that its good enough and you should be happy with it and not get it regulated. An automatic watch's precision is an integral part of what attracts them to most people. And +/-7s/day is not any sort of amazing horological achievement in this day and age. I'm not buying a Rolex solely for its looks. I'm buying it for its achievement in machining and precision, too. So, I wouldn't be satisfied if it performs no better than a $2,000 Tag and some sub-$500 Seikos.

Well Tudor got ETA non-COSC, so I did expect lower precision than my GMT II, but I agree that +7s was to much. Especially when 0.3s is achievable with the same movement!
I'm pleasantly surprised that it can run so precise.
By the way, all numbers are taken when wearing daily, not on the winder.
