Mine 1~2 sec everyday.

But long time never wear anymore. Use cellphone better.

Wow that’s really good! May you share what model is it?? Is it COSC certified?

Hey guys, let’s share if your mechanical/automatic watch is giving you accurate time day by day ??

For me: it seems like my watch has been slowed by 10 seconds every day (I never experienced it being fast before)

I compared it to my iPhone watch time  (min and second hand in my iPhone)

What/which watches of yours that you're referring to?

Guess all my auto watches got accuracy 'problem' be it swiss or japs. Faster/slower around 4 - 8 sec a day

Unlike any of my Quartz line up, all stays pretty good. In fact the JDMs are doing way better than the ETA   

How about your fav watch of all time? mind to share?

I just bought the Tissot Le Locle powermatic 80 I just owned it for several days and I realised from yesterday to now, it has slowed for 10seconds not sure will it be fast again if not it will be slowing down 10seconds per day and eventually the watch becomes slower and slower

Le Cocle is one hell of a very very well known serie/model. hhmmmm not sure about Powermatic movement but i think u should send it in to adjust the accuracy d else like u said it will become slower and slower.

Sorry I’m new to this, but is it just send it back to Tissot service Centre or just the authorised distributor I got my watch from ??

How long does it take for the whole process ??

One more thing, could it be the low power reserve which cause the watch to be going slower and slower ??

Hey there, a few things you can try is try to wind the movement about 20 winds and then let see how it goes from there. if let say still same thing persist, then u can send it in to Tissot's official / authorised service centre and tell that fella what's going on. They'll know what to do. This is pretty common in all automatic movements be it low tier to even higher tier.

power reserve will decrease gradually when u did not wear the watch oftenly, that's for sure. but like your case, i think it's slowing down by 10sec per day, that's a little bit a lot d for such class punya movement.

So, again, before u send in for recalibrate your movement, u try the above 1st. Watch is a very special kind of hobby and it's very luxury in its own way, observe and 'dive' into it before you proceed to next step  

Thanks for the advise bro

Just on a side note, will your watch actually be faster sometime ?? I just checked my watch again and it seems like it has slowed 2 seconds (after 8 hours). I know this watch is not COSC certified, but is it normal for it to constantly 10 seconds every day (-10) despite it is rated for (+ or - 10) per day ?

2 secs after 8 hours of running? That mean it's about 6 secs for 24hours. Which is not bad. This is a very common behaviour of an automatic watches. Unlike battery. They are more "consistent" in a way even the cheapest Miyota mvmt.

And since u just got your timepiece quite recently, give it a period of time running on your wrist and let's see from there.

Cheers mate

Thanks for the reply and input 

Just to update, i have been collecting data of it since 12th May 2018 (I know it is still too early to conclude), and it seems like it is slowing at a quite steady rate of 3 seconds per day.

My prediction for it is that it will continue to slow 3 seconds every day and with that, it will have slowed for 90 seconds in 1 month time.

Is this ok for an automatic watch which is not COSC certified?? I thought Automatic watch should have gained time in some days but so far i only experienced it losing time instead?    

Your tissot is not Chronometer certified which runs on an accuracy : Max. -4 or +6 second per day.

Yours is well within the specs and for sure, i think they wont entertain you. I have a watch running -1 to -3 secs a day and sometimes it becomes +3 secs a day. Not a problem for me coz it gained 1.5 mins after more than a month use.

Need to back and check my watch. In the drawer for years 

Thanks for the input sifu  So do you normally reset the time after perhaps several months of usage just to re-correct the deviation?

Just out of curiosity, how is the real life performance of a chronometer watch?? Like those high end Tag Heuer, IWC, Longines, Rolex or etc.

Is it possible for them to achieve an accuracy of +- 10 seconds per month (in other words very less deviation per day) ?

Better have it serviced after long time of not being used, and start wearing again.

My old trusty Tudor Pelagos once managed to maintain close to +1 / -1 variation for few days.

But it fluctuate depending on a lot of factors.

Basically, it's never went more than the COSC's specs and I expected it to run that way.

It is not mechanical. I have to go to Menara Goodhill for battery replacement    The battery last probably no less than 4 years I guess.

I change it when i feel like i cant stand the time deviation anymore. there's no set criteria for myself when i want to match the time again with world clock. the couple of time i change it is when it gained almost 2 mins

as for your 2nd question, i dont own any chronometer watch.. imma small time watch guy only

i guess it's possible to achieve 10 secs a month? there's few factors no? when i rest my watch flat for 12 hours and measure the accuracy and when i wear it for more than 12 hours... it became - when i dont wear it and when i wore it, it becomes +.

That also, as Everdying said in another discussion, accuracy also depends on how much power reserve are left in the watch

Silly to ask, is it required regulating if my watch seem run slower 20+sec per day.
regulating cost usually how much for seiko?

Have you tested and confirmed it has been running slow for 20seconds/day for at least a week or more?? That would mean more than 2 mins slow per week.

Yes, compare to my hand phone internet time and Seiko quartz.. a night ald slower 7 sec

May i know what model is it so that we can have a check on the movement it uses??

FYI, even a chronometer (COSC certified movement) has an accuracy of +6 / -4 seconds per day. So if for your case, it slows for 7 seconds after one whole day, it doesnt seem that bad enough for me. 

I understand the accuracy that y I compare 2 timer.. I believe hand phone is the most accurate coz it sync with world time server. My quartz no problem compare with hand phone .

I'm wearing a seiko skx007.. not 7 sec late per day is per night

I asked before in watchforum, it seems that that 7 sec slower is still ok. How long have you been using your watch? However I’m not so sure of Japanese movement but my Tissot is giving me constant 3 secs slow per 24 hours.

I keep track of it by comparing it with my phone (just like you did) every day at 7am, 3pm and 11pm. I have already gathered 7 days of data to do this analysis.

Maybe you can also do the same and monitor it for 1 week, and wear it everyday to make sure the power reserve is sufficient (more than half) before deciding whether to bring it to service Centre or not ?

Just 4 months old haha..
It is notice able after few days coz few minutes late.
Your case - 3 sec per day is good coz 2months later time dif 3min . For the watch with date u need to adjust the date after 2months and adjust the time together.

For my case,20+sec late per day if 2 months later the time difference is 20+mins . Omg

20 seconds slow per day is really horrible   

Since you owned this watch for 4 months, and have been wearing it for quite some time, i think it is better to bring your watch back to the service provider and have them regulate it for you. 

have to ald.. tq for advice

BTW, while waiting for the time to send in your watch, you can also try to position your watch differently every night. For eg:

1) horizontal with dial facing up
2) horizontal with dial facing down
3) vertical with crown facing up
4) vertical with 3 facing up (crown down)
5) vertical with 12 up (crown at the right)
6) vertical with 6 up (crown at the left)

and see if it makes any difference?? From what i have read, different position might actually making the watch either gain or lose time.

As in my case, i like to wear my watch on my right wrist, and so, most of my time the watch is at a position where the crown is facing up. Since i am also still new to this automatic watch, i will continue to try and update here from time to time.

Actually i plan to buy a tool to open it and regulating by myself   just youtube it seem quite easy.

It's not weird if it is WITHIN spec

They wont entertain you if it's within its spec. You just have to be less anal about it

True, but TS have the right to check with the AD and get post sales services. Maybe they could offer TS something spectacular!
Pelagos no love liao, cuz have BLNR, sell Pelagos cheap cheap to me lar.

Yup I know, but since it is my first automatic watch so.... haha. guess I will just have to live with it haha.
Asked hem and they told me it is very good as some of the problem unit are having an accuracy of +- 10mins per day 😨

P/s perhaps they just sell and don’t have knowledge in watches :/

Mechanical watch time will drift over time because machining mechanical part has imperfection due to machine tolerance.

Traditional battery watches runs on internal quartz or crystal oscillator which is very accurate but over long period will also drift. The microseconds inaccuracy is diving clock pulse will accumulate over time. Battery factor will only comes to very end of battery life cycle because the circuitry can be designed to drive at constant current.

If accuracy is very important, then you need to go for watches that sync with cellular base station or GPS. Your phone use clock data from cell station which is synchronized to GPS satellite. Yes, due to distance from satellite to earth, the info delay 1s+ (no more than 2s if not mistaken), but the GPS receiver has auto-compensation to calibrate itself. 

Lol I hardly wear the BLNR anyways. Maybe weekends, at most.

It's usually apple watch on the wrist for about 2~3 months.

Get a couple more of mechanical watch, then you will have different understanding in collecting watch. Accuracy is part of it but it will be less important as the journey progress... Only thing that is important is the $$$ in the pocket.

Agree on the part of very accurate time keeping, mechanical watches will fade, but I don't see Rolex or Omega or Patek slowing down, in fact the demand to fine craftsmanship have surge as the people has growth in wealth. Not everyone need to have clock that tell to exact mili to nano seconds, in fact sometime I do wear watches that stop working, but the presence of having a mechanical watch on the wrist play the tricks on people's mind, especially the subconscious.

It is no more about time accuracy when person wear those watches 

Aiyo, wasting wrist time liao. Use it as daily beater lar, ceramic bezel mar. 

Would love to, but the mistress is wearing it mostly on her wrist anyways 

But so far, nothing ill has happen to the BLNR yet. Still shiny and pristine since the day it was collected from a close friend.

Some tips can found from above link

Well experienced watch repairer told me late 20+sec per day is normal for entry lvl automatic watch

Thanks for sharing, that link is super useful!

But are you satisfied of your watch being slow constantly at 20seconds per 24 hours ??

P/s to update, my watch just lost 0.5 seconds in 24 hours since yesterday! Wow! And I let it in the crown up position when I Went to bed. Will try another position tonight

Not satisfied but no choice, u need to pay higher price for higher end movement .

As u said, different position will affect the beat rate..

Bro, my friend Seiko 5 (which he bought for around rm500) is keeping quite good time according to him, at only +- 10 seconds per day

Lol , maybe I'm the unlucky one...

Just to update, it has just run fast for the first ever time of me owning this watch (+1 sec per day)

P/s mechanical watch is really a magnificent invention

i done regulation, rm10 per time   still not so accurate but better than before.. when i return it watch shop to regulate again keep insist required service/overhaul my watch.. black shop

Hey guys, let’s share if your mechanical/automatic watch is giving you accurate time day by day ??

For me: it seems like my watch has been slowed by 10 seconds every day (I never experienced it being fast before)

I compared it to my iPhone watch time  (min and second hand in my iPhone)

What's your watch? If it's a subbrand then the precision depends on the movement manufacturer. Jody on Just One More Watch mentioned that what you're looking for in a movement goes by this order. Miyota 9k series, seiko nh, Miyota 8k and the rest.

Precision is highly relative to its brand.

Just my thoughts though.

My watch is the Tissot Le locle powermatic 80. I think it’s heart is the modified ETA 2824-2

Mind sharing the name of the shop so that all of us here be aware of it ?
