But the upcoming Apple Watch Series 4 could introduce the first obvious changes to the core hardware itself, if rumours prove true. Details have started to build up ahead of a potential launch later in 2018, and the Series 4 might be the revision that gets original Apple Watch buyers to finally splurge on an upgrade.
Eager to slap a new smartwatch on your wrist? Here's what we've heard so far.
When will the Apple Watch Series 4 be out?
Unsurprisingly, we're expecting to see the Apple Watch Series 4 debut this September alongside the purported new "iPhone XI" models. Bloomberg reports that Apple is "preparing another big push for the wearable hardware later this year," and that's the timeframe we expect for Apple debuts.
If the Series 4 is launching later this year, then we definitely expect it in September.
How much will the Apple Watch Series 4 cost?
There aren't any solid rumours about the Apple Watch Series 4's launch price just yet, but let's look to history to see where it's trending.
The Series 2 models started at £369, but then Apple cut the entry point a bit by giving the Wi-Fi model of the Series 3 a £329 starting price. Granted, they were also trying to sell pricier Cellular models, but it felt like a nice deal on the bottom end.
Even if we see an enhanced screen (keep reading), we have to think Apple won't try to bump the price too much for the Series 4.
It's a total shot in the dark, but a starting price point around £329-349 for the Apple Watch Series 4 seems reasonable in our eyes.
What will the Apple Watch Series 4 look like?
Despite some users' hopes for a circular version, Apple hasn't changed the silhouette of the Apple Watch (Series 3 shown) from the start – and that may stay true with Series 4.
Bloomberg reports that Apple is working on "a pair of new Apple Watches that keep the overall size of the current models," and that they will still work with bands made for the current and previous editions.
We'd be very surprised to see any dramatic shifts this year, but there's still room for enhancement within the current design.
What about the Apple Watch Series 4's screen?
Now here's where the Apple Watch Series 4 may finally bring some visible change over the previous models: the display.
Since the start, Apple has used small OLED displays at 326 pixels per inch on both the 38mm and 42mm sizes – but they've had a bit of bezel around the screen itself. Not this time, according to Bloomberg. The site reports that Apple will feature "slightly larger, edge-to-edge screens" in the Apple Watch Series 4.
In other words, they're going for the iPhone X approach this time around - with no notch, we hope. Granted, there isn't that much bezel on the Apple Watch now, so we'll have to see whether it's really a noticeable difference or not.
In July, analyst Ming-Chi Kuo from TF International Securities suggested that the displays will stretch to 1.57in and 1.78in, respectively, wih the current models measuring at approximately 1.5in and 1.65in. Like we said, it won't be a huge difference if true, but the trimmed bezel could result in a much more appealing aesthetic.
Improving the screen is one way to make the Series 4 stand out without totally overhauling the design. We think it'll happen.
How much power will the Apple Watch Series 4 pack?
The Apple Watch Series 3's S3 chip is a pretty powerful little wearable processor, and last year's Watch revision also packed in more RAM than before.
We expect further incremental improvement with an Apple S4 chip in the Series 4, and quite likely the same amount of RAM as the S3 (768MB) or maybe bumped up to 1GB. You don't need that much processing grunt for a smartwatch, but every little bit helps.
It'll almost certainly be called the S4 chip, but we'll have to wait and see whether it brings any significant enhancements over the S3.
Is there anything else I should know about the Apple Watch Series 4?
If it launches later this year as expected, then the Apple Watch Series 4 will launch with the newly-revealed watchOS 5 installed. Of course, it's also coming to past Apple Watch models, with the exception of the original 2015 release.
As we've explored, watchOS 5 brings a number of feature enhancements to the Apple Watch, including a Walkie Talkie app for swapping quick voice messages with trusted contacts, as well as enhanced workout tracking and Activity Competitions, Podcasts support, and improved Siri usage and notifications.
In April, there was a bit of buzz around discovered watchOS 4 code that supposedly pointed to the possibility of third-party watch faces in the future, but it sounds like the hype was unfounded. That's a shame, since third-party faces might be our most-wanted Apple Watch feature after all this time.
Analyst Ming-Chi Kuo also believes that the new Apple Watches will feature "enhanced heart rate detection," although he didn't elaborate on what exactly that will mean.
While watchOS 5 sounds like it'll bring a number of nice enhancements, we're not getting our hopes up for third-party faces this year – Apple would have already announced that feature at WWDC with the rest.
