Display
As with just about everything these days, display matters quite a bit. In a lot of ways, the wearable segment has display requirements similar to the smartphone space. However, unlike the smartphone space it isn’t necessarily critical to have the highest possible resolution, and it isn’t necessarily crucial to have perfect color calibration as in most cases wearables won’t be used for color-critical applications.
In the interest of addressing this, for the near-term we’ll continue to use the standard smartphone workflow, but I hope to expand the testing done here as wearables develop. For now, we’ll continue to do the standard brightness and accuracy testing, but I’ve removed the grayscale test as it strongly emphasizes gamma accuracy. Although it is important to not have obscenely incorrect gamma curves, wearables generally have to prioritize readability over dynamic range, which means that near-black colors would be brightened to try and overcome background reflectance. Similarly, we won’t be placing dE2000 average error in our Bench comparison tool or in graphs, as something like the Apple Watch cannot have controlled display brightness.
As a result, we can’t really be 100% sure that gamma tests and other tests of luminance are actually accurate when automatic brightness means that any inconsistency in light to the sensor will affect display brightness, which will strongly affect dE2000 results.
In the case of the Apple Watch, the display is interesting because this represents the first AMOLED display to ever be used in an Apple product. As far as I can tell, this is an LG OLED display with an RGB subpixel arrangement, but it isn’t quite the same as a traditional RGB stripe. I suspect that for the near future we will continue to see the use of this subpixel arrangement as the resolution of the Apple Watch doesn’t really allow for a PenTile layout. Given the current state of AMOLED (as evidenced by the Galaxy S6) I believe it is effectively the future of mobile displays, and it seems that whoever makes these decisions at Apple agrees as well.
As I mentioned in the start of this section, the Apple Watch also doesn’t have any way of manually setting brightness. You get approximately three choices of auto brightness algorithms, which bias the brightness curve of the display appropriately.
In practice, I didn’t actually care that manual brightness was gone on the watch because I never actually used manual brightness on the iPhone or any phone that has at least a halfway decent auto brightness system. In every phone I’ve ever used, the only time I use manual brightness is when the auto brightness system is clearly programmed wrong in some shape or form. Common cases where this would happen include auto brightness that didn’t actually set the display to maximum brightness in daytime or wouldn’t set the display to minimum brightness in absolute darkness.
Thankfully, the default auto brightness setting on the Apple Watch doesn’t have any of these problems, although for reasons unclear minimum brightness changes depending upon the brightness setting that is selected. As a reviewer though, it would definitely help if the watch had a manual brightness setting for more precise display testing and battery life testing. I’m sure that the precision of the digital crown would allow for precise brightness settings as well, but I suspect that this would have some very real potential to affect practical battery life as I’ve seen more than one person walk around with their smartphone display permanently set to maximum brightness because of reasons.
There’s also the issue of reflectance, which could be a problem given that the two higher-end models use a sapphire crystal glass on the display instead of traditional hardened glass. I did notice that reflectance is much higher than something like the iPad Air 2, but I never really felt like the reflections completely washed out the display. The reflections also indicate that the watch has a properly laminated display, without issues involving index of refraction mismatch. However, if people are worried about outdoor visibility Apple Watch Sport should be better given the use of more common aluminosilicate glass. I’m not sure if Apple has actually loaded different auto brightness algorithms for the Apple Watch/Watch Edition compared to the Watch Sport to try and compensate for this though, and I suspect such a change would be difficult to test for as well.
Although reflectance is one aspect of outdoor visibility, the other is display brightness. This is probably the only aspect of the Apple Watch where I can get consistent and repeatable results. Unfortunately, given that we haven’t actually done any other full-featured wearable reviews I’ll have to reference smartphones to get a good comparison point. As the Apple Watch display is already quite small, we won’t be able to get accurate APL vs brightness readings as it’s impossible to hold the meter in a repeatable position that isolates ambient light while also holding an LED to the display.
At any rate, the Apple Watch gets respectably bright at around 460-470 nits, although not quite the ridiculous 600 nits that the Galaxy S6 can achieve. At this full white display, I recorded a color temperature of 6891K, and 6883K at the ~100 nits that was used for the remainder of display testing. It’s important to keep in mind that these values are only at 100% white, so this isn’t the average color temperature that we normally list in reviews. Of course, this display’s contrast is also infinite, with no visible residual brightness on pure black images.
Saturation Sweep
Moving on to the saturation test, we can see that Apple has put a huge amount of effort into calibrating these displays, which is somewhat surprising given that one might expect wearables to not be all that critical when it comes to color accuracy. In my experience, I never actually bothered looking at photos on the watch outside of the messaging app and Twitter. I suspect that this was done in order to make it so that images look the same across all Apple devices, as something would seem “off” in most photos taken by an iPhone 6 if displayed with an Adobe RGB gamut. In this test, the dE2000 average error was 2.33, and as one might guess from the photo above most of the error was concentrated in blue, which appears to have some gamut issues as the native gamut appears to be wider than sRGB but not enough to completely cover sRGB.
GretagMacbeth ColorChecker
The GretagMacbeth ColorChecker test reveals a similar surprising level of attention to detail in color calibration. Color accuracy isn’t quite on par with the very best, but given that this is a first generation product I’m really surprised that the display is already receiving this much attention with an average dE2000 error of 2.42. Overall, this means that the display has relatively little perceivable error for sRGB content, which is the standard almost across the board, although wider gamuts like Rec. 2020 or Adobe RGB may one day supplant sRGB.
Overall, I’m impressed with the quality of the display of the Apple Watch. The AMOLED panel could probably reach a 600 nit max with sufficient progression in emitter technology from LGD, but I suspect this will take some time. The calibration is also incredible for a first-generation wearable, and the use of a full RGB subpixel helps to avoid a lot of the aliasing issues that tend to plague PenTile or other RG/BG subpixel arrangements at these relatively low pixel densities.
The reflectance of the sapphire lens on the display is a bit high and could probably benefit from anti-reflective coatings of some sort, but given that I haven’t had to worry about scratching the display thus far it’s probably a fair trade as a screen protector will usually increase reflectance noticeably. It’s also a bit annoying as a reviewer to not have manual brightness settings, but as an end user I never felt the need for manual brightness as the auto brightness algorithm works quite well.
Ultimately the entire user experience around the display in every aspect is well-executed, although there is still room for improvement on the technology side of things.

You're so right! Use the watch for what it's intended for. It's not a computer. According to the guys at http://www.watchtimely.com it was originally meant to have a slightly larger screen to be able to do more complicated things, but the developers realized nobody would do them on their watch anyway.xihan94 - Friday, September 11, 2015 - link

... you seem to have a tremendous amount of time on your hands. Perhaps learning a new skill would be valuable?Schickenipple - Tuesday, July 21, 2015 - link
This guy has written book-length posts on pretty much every Apple product review. It's quite sad, really.I'd have to imagine that ANY skill other than ranting on and on about something he's never even used would go a long way... A career, maybe?

Dera BittenRottenApple,Excellent Analysis, what a great read, rationally and logically consistent, thank you very much.
By the way, some further recommendations to read and watch:

Other Apple news not mentioned here:
Apple Watch sales fall by 90 per cent
Apple has another lemon
It is turning out exactly as we said – sales of Apple's latest cure for cancer have slumped to a shadow of their initial "glory."
While the Tame Apple Press and a big chunk of analysts sung praises for the iWatch, claiming it would sell 70 million in its first year. We pointed out that the gizmo was nearly two years out of date and lacked most of the software which would make it moderately useful and if it succeed it was a triumph of user stupidity and marketing.
Lately analysts have been slowly withdrawing the enthusiastic sales figures they gave the watch, and now a new survey has shown that sales have fallen by 90 per cent.
Apple is selling fewer than 20,000 watches a day in the US since the initial surge in April, and on some days fewer than 10,000. This is not too bad, but it does suggest that most people who wanted an iWatch have one, and existing users are not managing to win many converts amongst their friends to make it take off. For the record to make the 70 million figure apple would have to sell 195,000 a day.
Data collected by Slice Intelligence show that Two-thirds of the watches sold so far have been the lower-profit "Sport" version, whose price starts at $349, according to Slice, rather than the costlier and more advanced models that start at $549. Apple's gold "Edition" model priced at $10,000 or more has only sold 2,000 of them have been sold in the US.
The figures are based on the electronic receipts sent to millions of email addresses following purchases. The company conducts market research on behalf of consumer-goods companies, among others, many of them in the Fortune 500.
All up though these figures are not bad, but they are not the sort of numbers which Apple needs to convince its investors that it can make mega sales any more. With sales drying up in China, Jobs mob will not have a good bottom line this year.

And
Apple puts iWatch in stores
Maybe some idiot will buy them
Apple mysteriously has enough iWatches on hand to start putting them in its own stores.
The iWatch went on sale six weeks ago and at the time Apple did not think it would ever have enough to put it in its own shops. The original plan was to flog them online and in fashion stores, however and Jobs' Mob thought it would never have enough to meet the crushing demand for an out-of-date wearable which was more expensive than anything else on the market.
So it appears that suddenly Apple has enough. Of course the Tame Apple Press is trying to keep the story about a shortage going. Potential buyers must first reserve their device online, and some models are still out of stock.
But the sport models, which are most popular and the cheapest, are available across the country, while others can be bought in Apple's flagship shops, such as those in London and Manchester.
In order to reserve your device, you must pick the Watch you want to buy, choose a store to pick the device up and then choose a time to go and buy it.
You can also order the home delivery, but it's not recommended as it takes more than three weeks for the shipment to be delivered.
The most expensive models, such as the 38mm yellow gold model with red modern Buckle strap, are still unavailable. As Apple said last week, the 42mm Watch in Space Black with the metal link bracelet is unavailable at all stores for now.

In the interest of transparency, BittenRottenApple has been banned from AnandTech. We have since identified him as a sockpuppet having used multiple accounts here, and while we afford our readers a great deal of liberty to discuss products and articles, we will not put up with people who are dishonest in their actions.Dennis Travis - Wednesday, July 22, 2015 - link
Ryan, thank you. It's for the good of the site. I was about to reply to him but glad I read this first!Again thanks for getting rid of people like that. Just brings the whole comments section down.
colonelclaw - Wednesday, July 22, 2015 - link
Thanks for that Ryan, on the internet it's easy to say "you need to get some kind of help" in jest, but in this case I think it may actually be true. Presumably iWatchHogwash is the same person?sammery - Tuesday, July 21, 2015 - link
Goodness me. That was so long and devoid of meaning I might start using it instead of Lorem Ipsum.WinterCharm - Tuesday, July 21, 2015 - link
Take your neurotic apple hating bullshit elsewhere.You're just bitter that Anandtech gave the watch a stellar review.
