Very well Apple. I have two Macs, three iPads and two iPhones in my household. No device shows the same time as any other, and they all differ within a approximately 3 minute span. Please use the tech technology in your other products too. Please.
Got a tip for us?

Apple's Kevin Lynch Explains Method Behind Apple Watch's Precise Timekeeping

Atomic timekeeping watches usually have about 1 second of error. Its time is originated from atomic clock, but transmission delay is at ~1ms per 300KM distance to the radio transmitter. So, the signal itself is about 10ms late to begin with. Also, watches has its own delay because they are more interested in power saving then keeping accurate time. When they sync with the radio transmitter at night, they would just receive the data and correct itself at the next second.
nothing to do with the watch, iphone just passes the data to the watch.
Might as well read, Iphone provides precise timekeeping.

Milliseconds...Schmilliseconds.
Just give us a watch with a round face so we don't look like we have a computer attached to our wrists, will ya?

Even as an owner of an Apple Watch that I wear daily I think this is ridiculous.
It's a digital watch that syncs time with NTP time servers. Just like my Windows PC, my Macintosh, my iPhone. It's hardly special.

Honestly I could care less if it were a few seconds off but the tech behind keeping it so accurate is cool.
Wasn't he the bozo who was making blog posts disputing Job' Thoughts on Flash letter?
That's actually the true reason why the iPhone needs very precise time. If the phone is closely synchronized to GPS time, the chipset can do less searching for the GPS signal, making position acquisition much faster and saving power. If you check the iOS logs, you can guess that it syncs first via the Internet, then uses that to acquire the GPS signal, and then keeps time based on that.
I bet the synchronization error is mostly in software from that point on. Unless you specifically engineer in high precision clock hardware, you can't get better than a few milliseconds.
It's Apple reality distortion field in practice. it's the same as saying "magical" and "innovative" before everything. It makes buyers feel good.
And people will lap it up as reality because someone at apple said it
The phone does the same thing and it syncs with the phone. Nothing special here.
I find a watch with a bunch of mechanical parts such as gears, springs, balance, far more interesting then one with a chip that practically everything has in it these days even if it is less accurate. The Apple watch is a disposable watch that will be useful for about 3-4 years max before its tossed. Many will replace it every year . A nice Submariner will last a lifetime and go up in value. Yes I do have the Apple watch but it gets about 1 day of wrist time a week and when I wear it I miss the mechanical Swiss ones.

These kind of comments never get old!! I don't want it, therefore nobody wants it ( assuming you weren't being sarcastic)
A round face once you are displaying time in more than a traditional circular clock layout is incredibly limiting. I hoe Apple doubles down on a square screen and just works on making a better looking watch. When it comes to smart watches a circular screen feels like a failure to me.
Actually, the fact that they have thermocompensated quartz in the watch is interesting. "Typical" quartz watches are accurate to a few minutes a year. High-frequency thermocompensated quartz can be accurate to 5-10 seconds a year. This is all without any atomic time syncing, mind you. From the description, it sounds like Apple went with high accuracy Quartz even though they sync atomically. This is complete overkill. Even the crappiest Quartz movements are accurate to less than a second a day, so there is little reason to use a good one if you're syncing to an atomic clock.
Basically, between the frequent syncing, latency compensation, and high accuracy Quartz, it really is impressively accurate. They could have not bothered with any of that and it would still have been within a few seconds at any given time from atomic syncing alone, but they went above and beyond.
This is BS considering the the watch connects to the internet through iPhone. Which obviously syncs to a centralized server maybe theirs or straight to the atomic time clock server. Besides I'm still gonna clock-in to work just right the time they needed me. Or show up to a group of friends arguing that I got there right in time to the most accurate seconds.

lol, the whining and bashing in here is hysterical. they talk about cool technology behind their products...then fanboys whine that they don't care about updating tech in their Mac Pro or other products...wah wah wah.
Each Apple Watch has a temperature-controlled crystal oscillator inside to combat time drift that clocks and watches see. The oscillator also makes sure the Apple Watch remains warm enough to keep accurate time in very cold climates.
This is the bit that's interesting to me. I find that my iPhone becomes nearly useless in very low temperatures. When I go skiing or backpacking and it's 10 degrees Fahrenheit or lower, even with 100% charge, within an hour or two the battery goes dead and that's with it inside my coat where there's body heat. I learned a long time ago that even a relatively cheap Timex Ironman watch will fare better than my iPhone in these conditions.
Does anyone with an apple watch know how long the battery lasts in very low temps?
Apple is not doing anything unique here, NTP servers are a standard across IT. Your computer even sync time automatically.

Acter a whole life of too-fast Rolex watches and imprecise digital garbage, I enjoy the Watch perfection a lot.
My beef about almost all the smartwatches I've had, is that they usually don't have any way to manually set the time.
Nothing dumber than having the battery die, then recharging the watch so it can work again.. BUT without a phone or hotspot nearby for it to sync to, the watchface shows some random time that cannot be set manually to match a nearby clock.
Doesn't happen often, but in the woods or if your phone has died, it's just ridiculous. All the accuracy in the world doesn't help if it cannot get a base time. (Does anyone know of a manual time setting app for the Apple or Android watches?)

Sure - obsessed with working hard to be able to afford that
watch. Not too many people are actually wasting time, although to someone who has no family ties, it might appear that spending time with one's family is a waste of time.So we're to believe that the iPhone receives the pretty accurate time signal via the internet, like any mobile phone, then it uses software to adjust for the time lag in getting the signal through the internet and onto the Apple watch.
My guess is the Apple watch and iPhone must stay on the same time and the iPhone is just as accurate.

I'm usually okay if I'm 50 milliseconds late for something. It's cool and all...but maybe they should focus on things that matter more? I think maybe Apple is trying to convince us that there is a problem (that they fixed) when there never really was a problem to begin with. I don't know. Just my 2 cents.
