Mine 1~2 sec everyday.

But long time never wear anymore. Use cellphone better.

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?

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.

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  

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

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 

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?

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

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

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

have to ald.. tq for advice

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.

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. 

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

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

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.  :thumbsup:

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.
