Apple Watch 7 (AW7) – predictions

The Apple Watch 7 (AW7) will be announced on Tuesday 10th September 2021 and will run watchOS 8, first released in June 2021 (beta). Many of the software features could already be running in beta on your Apple Watch 6 well before the Watch 7 appears. Thus unless there are new hardware formats of AW7, its release will be somewhat of an anti-climax. Other than tweaks to screen, memory, performance or some other tiny detail, its release will be a #shrug moment.

That said, there’s a reasonable chance this year will be different!

Headlines to Watch Out For

Here are the key moves for the Apple Watch; further below I’ll discuss the chances of them happening this year along with other minor product changes:

Background: Apple Watch 6 – Current model

For those of us who like to deduce Apple’s next move, this is crucial information. Apple makes certain regional filings in advance of the launch date which tells us how many variants are planned. Thus we expect 6 variants for the AW7. If there are 12 variants registered then this could well mean the introduction of a round face series alongside the traditional rectangular face. Or it could mean that the 12 variants are the SE2 and AW7! There are other clues too but I’ll not mention them for now as only 6 variants have actually already been registered 😉

There are 6 CURRENT models of the Apple Watch 6 (AW6), namely these

  • GPS: A2291 (40mm), A2292 (44mm)
  • GPS + Cellular: North America: A2293 (40mm) A2294 (44mm)
    Europe, Asia Pacific, and China mainland: A2375 (40mm) A2376 (44mm)

[these same 6 variants have effectively been confirmed for AW7]

and there are 6 models of the Apple Watch SE, namely these

  • GPS: A2351 (40mm), A2352 (44mm)
  • GPS + Cellular: North America: A2353 (40mm) A2354 (44mm)
    Europe, Asia Pacific, and China mainland: A2355 (40mm) A2356 (44mm)

[There will almost certainly NOT be an SE gen 2 in 2021, a PRO version is plausible]

Then there are cosmetic variants differentiated by combinations of cases, bands, and exclusive watch faces. Here’s a quick overview of these ‘collections’ which we could crudely classify as cheap or expensive:

  • Apple Watch SE – aluminium case (cheap)
  • Apple Watch – aluminium/stainless steel cases (cheap/mid-price)
  • Apple Watch Edition – ceramic/titanium cases (expensive)

then we have special co-branded collections

  • Apple Watch SE Nike – aluminium case and Nike band/face (cheap)
  • Apple Watch Nike+ (formerly Sport) – aluminium case and Nike bands/faces (cheap)
  • Apple Watch Hermes – stainless steel case and Hermes leather/sport band (expensive)

Background: Apple Watch Evolution w/Notes

I will go into some detail here as the evolution of the innards of the Apple Watch is surprising. Interestingly, the previous Apple Watch 5 (AW5) coincided with the end of the life cycles of several of its components – more change was due with AW6 than we saw, change is coming with AW7. Here are examples of precisely what I mean

  • AW2 (Glonass), AW3-AW6 (Glonass, Galileo, QZSS) – with China a key market for Apple I would expect Beidou support.
  • AW1-AW5 all have WiFi 4 (up to 802.11n, 2.4GHz) with AW6 & AW SE introducing the 5Ghz band to allows faster dual-band connections with a new WiFi chip – Yet Wi‑Fi 5 (802.11ac) is in widespread use and Apple Watch’s new W3 chip may already be capable of running faster Wi-Fi connections and maybe also capable of running 802.11ax 2.4/5Ghz/WiFi 6 (Feb 2021) in years to come. This chip was released for Apple Watch 4, so it’s not that new.
  • AW2 saw the introduction of WR50 water resistance, WR50 (50m) is sufficient.
  • AW4/5 saw the introduction of EKG/ECG to an improved optical HR sensor as well as an improved gyroscope and AW SE uses this sensor. AW6 has a wholly new and more accurate sensor further supporting SpO2. This sensor was updated in 2020 and I argue will support capabilities not yet enabled.
  • AW5 got the first compass and AW3 got the first barometric altimeter, and AW6 claimed to have the altimeter always-on for the first time.
  • With the exception of AW3, every Apple Watch version modifies display functionality in some way whilst retaining a constant 326ppi resolution. AW SE retains the same screen as AW4 (kinda) and AW6 has a brighter screen in sunlight compared to AW5 and loses Force Touch 
  • AW4 saw increased screen sizes for both the ‘small’ and ‘larger’ screen models, so the size of the Apple Watch screen remaining constant is not a given. The rounded rectangle is a consistent format for the Apple Watch.
  • Apart from AW SE, every model has received a new processor (AW4/5/6/SE=64bit dual)
  • Apart from AW2/SE/6, every model has received increased storage (AW5/SE/AW6=32Gb)
  • RAM has never remained the same on 3 consecutive models. AW4/5 are both the same on 1Gb DRAM and AW6/SE is unknown
  • AW4/5/6 each had launch prices of $399+
  • AW4 saw Bluetooth 5.0 introduced (v5.2 is latest available standard, Dec 2019)
  • AW6 is the first with UWB capability (Ultra Wideband) but not (yet) with the precision finding component of Find My.
  • AW1 onwards had an ambient light sensor
  • No AW yet has been able to sense body/skin/core temperature.
  • Every AW has a different battery capacity using the same fundamental technology. AW6 has the best capacity so far.

That was all factual stuff you can check out on the Apple website and elsewhere.

Is caution needed when extrapolating from past evolutions?

Some of the historic trends from the previous section are relatively easy to see with some components updated annually and others less frequently. Thus AW7 will NOT have either a new WiFi chip or new optical HR sensor but it will almost certainly have a slightly faster S7 CPU.

There is usually at least one entirely new piece of tech capability that is introduced each year, despite AW6 appearing to be a ‘boring release’ it had these: new oHRM, new WiFi chip and new UWB. UWB seems ‘boring’ because there is no accessory hardware that currently works with that capability. Apple AirTag (locating tag, Q2.2021) WILL use UWB.

Looking at a seemingly unchanged specification item may disguise an underlying hardware improvement that either improves battery life OR has functionality that is not yet enabled. For example, it is feasible that the AW6 is still using the same GNSS chip as the AW3. Yet, there have been notable GNSS chip power consumption improvements elsewhere in the market and Apple needs efficient components…GNSS is a key place to achieve that. So, either they’ve already silently replaced the GNSS chip with a more efficient one or that change is well overdue.

Similarly, although Bluetooth 5.0 is the headline spec, Bluetooth 5.2 offers battery savings for audio playback and it’s inconceivable to think that Apple won’t soon pounce on those. BLE 5.2 also supports multiple pairings but AW7 doesn’t need those.

There have been no worthwhile leaks so far for the AW7 but there have been patents filed by Apple. This does NOT mean that the patent will be used in the next model, indeed a patent might never be used. Apple HAS filed patents for circular watches and for buttons that replace the crown.

Final Pass: Apple Watch 7 Specifications Speculations

Just extrapolating from the past and adding in some credible, known patent filings we deduce this

  • AW7 will be released in September 2021, probably Tuesday 10th or Wed 11th (news cycles are important)
  • AW7 will start at $399
    • The Hermes, Edition and Nike Collections will continue 99%
    • There will be a new strap design and/or strap colour 95%
  • AW7 will be slightly faster and slightly more battery efficient 🙂
    • delivering a marginally faster experience but, more importantly, a more energy-efficient architecture to support a close-to 2-day battery life 90%
    • a better-performing, smaller CPU, labelled S7 99%
    • 64-bit quad-core processor 95%, 128bit won’t happen.
    • 64 Gb storage 40%
    • 2 Gb DRAM 70%
    • Wholly new battery tech 10%
    • Improved battery capacity from 303.8 mA·h to perhaps 320 mA· close to 10% increase from a larger battery (see case size increases). 80%
  • AW7 will retain the current size formats, this time it will most likely be square-edged and rectangular although circular formats will be added in years to come (Analyst: Ming-Chi Kuo)
    • 40/44mm versions and LTE/non-LTE version will be retained, indeed the basic rectangular case design will be similar to AW6 30%  (41mm and 45mm rumoured)
    • Circular watch face as either a total redesign 1% or as an optional format 1%
    • More square-edged design but still rectangular 95%
    • Larger screen & Case sizes have been strongly rumoured from multiple sources – 90%
    • Slightly deeper/thicker design (9mm to 10.7mm) 95%
    • Removal of the crown? 30% The crown will eventually go on AW8/9 40%.
    • A ‘PRO’ Version (GPS+Cellular only model) makes sense from a price perspective and ties in with known EEC product codes and with other Apple product ranges, but what extra software features warrant a Pro model designation? 20%
    • Smaller, child-targeted version 0%
  • AW7 is due for an improved GNSS chip both in terms of modern levels of power consumption and the ability to support Beidou. AW6 could already have that chip, Beidou could simply be enabled.
  • AW7 will not have a new WiFi chip (will be the same)
  • AW7 will have new Precision Finding UWB capabilities for Find My (Aw6 may or may not get these)
  • AW7 will not have new barometric altimetry capabilities (will be the same)
  • AW7 does not need WR100 water resistance. (will be same)
  • AW7 will not get a new oHRM 99%. However, AW6’s sensor IS likely to find its way onto subsequent models including AW SE gen 2 (2022)  99%
    • Sensor fusion between the accelerometers and oHRM will enable more safety & wellness functions, that includes accidents (an elderly trip or a bike crash), sleep, medical alerts (AFib, SpO2), wider female health features and a ‘help mommy! I’m about to be mugged alert’ 80%. The commercial importance of some of these feature sets cannot be overstated.
  • AW7’s new sensor will be the accelerometer-based RESPIRATION RATE (100%) however there might also be a (basal) body temperature sensor (5%). Whilst that appears to be a #Shrug moment these two sensors would further improve sleep stage detection, fertility tracking accuracy and early detection of some illnesses. And those three features are BIG, BIG features on smartwatches. If you want to bet on an unknown…this would be the one. However, body temperature sensing has been leaked to happen on AW8
    • To include body temperature measurements 5% (AW8 in 2022 90%!)
    • Prototypes already exist for a LASER-BASED Apple Glucose monitor (blood sugar/diabetes) from component supplier Rockley Phototronics. The commercial imperative also exists to release this tech however I strongly suspect that Apple is a few years away from having finalised, non-invasive glucose monitoring with FDA approval. I even doubt the AW8 will have this. 5%
    • Sensor vendors already have blood pressure working, and Apple has some hardware patents here. I just can’t see Apple introducing a watch with a blow-up balloon on the underside nor one which requires periodic calibration against a good source (like Samsung). That said, there is a commercial imperative to deliver this feature! 5%
  • AW7 will get wider connectivity to external devices – AirTAG, we’ve already talked about 100%, I’m thinking more about GymKit (which is stated for the AW7 in 2021, albeit probably initially limited) 100% (phased). Support for Bluetooth/BLE/FTMS sensors already exists in the SDK, support for ANT+ is unlikely (1%). Wider GymKit capabilities might be announced slightly later in 2021 when expansions to the Fitness+ service are announced.
  • AW7 will still have a magnetic compass
  • AW7’s screen is more of an enigma. Something ‘new’ will happen as the current tech seems to have gone as far as it can. We could see a more battery efficient micro-LED/mini-LED screen or a round format as the next evolution….both together could be risky. 50% chance we will see one of them. Highly likely there will be other screen tweaks including new lamination and smaller unusable edge area (aka a larger screen)
  • AW7 may well not need increased capacity above 32Gb. Realistically, disk space is mostly used for music and cached maps/video. Disk space is cheap, the issue is that the physical unit would be very slightly larger (and hence the space for the battery very slightly less)
  • AW7 will NOT support lossless audio (ALAC CODEC) due to Bluetooth restrictions, although AptX Lossless (2021) shows that lossless over Bluetooth is just about possible.
  • AW7’s RAM is unknown. If the DRAM is currently 1Gb then will further increasing it make any material difference to the performance vs space equation?
  • AW7 gets Bluetooth 5.2 support to lower the power needed for audio playback 30%.

I don’t think any of those predictions are exciting. Sorry. But they don’t need to be exciting for the creep of ever-better Apple Watches to continue. Remember, Apple Watch is only 5 buttons and a decent battery life away from wiping Garmin from the NASDAQ. That’s not so much of a techy change for such a commercial upheaval.

Further cautionary points:

Apple was sufficiently secretive to be able to release the SE version without anyone knowing until Summer 2020! So it should be able to sneak something equally as significant out for 2021.

Extrapolating from the past is fine…until it isn’t. Thus the AW SE saw an unpredicted disruption to the annual AW release cycle. It’s a reasonable guess that the AW SE2 could move to a 2-year refresh cycle but why couldn’t the AW6/7/8 also move to a bi-annual cycle? Why not circular or PRO model iterations one year and the two rectangular ones iterate the next? Or a bi-annual PRO version? Or some variation on that theme?

Second Pass: Health & Fitness Features

MUST READ: watchOS 8 Known Features

Apple Watch is clearly an extension of your iPhone. Yet, the future of the Apple Watch uniquely lies in becoming ever more independent of the phone and able to sense biometrics from your body as well as sense environmental interactions, the latter includes sensing your ‘speed’ for fitness purposes.

Apple Watch is a wearable, an iPhone isn’t. AW also requires connectivity to external fitness sensors for the longer-term support of fitness and athletic endeavours beyond GymKit. I don’t think Apple has too much urgency on that aspect, remember Apple tends to focus on its ecosystem first and foremost.

Whilst the Fitbit Sense introduced EDA scans and core/skin temperature, I don’t believe that Apple has to respond to Fitbit per se. It’s more that Apple will progressively respond to the needs of a loyal and growing customer base.

Elsewhere there is a first-mover advantage and massive profits to be had. Financial urgency comes from a magical solution to non-invasively measured blood pressure, hydration and/or blood sugar. Blood pressure readings are plausible, the other two aren’t. The tech isn’t there yet despite a few patents that people will cite in the comments below. Then there is a micro-fine tightrope that needs to be walked with the FDA, if Apple claims to produce medical-grade devices then it has a whole host of responsibilities and risks to manage. Trying to claim that a blood pressure sensor is some sort of indicative health tool rather than a medical sensor wouldn’t pass with me, maybe the FDA are more of a pushover? Hmmm.

In my opinion, extended GymKit support and a BODY TEMPERATURE sensor are vastly more likely in the AW7 than a hydration sensor, a blood glucose sensor or a blood pressure sensor, simply because they are vastly easier and it makes sense to do the easy stuff first, so long as people want it. People patently DO want sleep, fertility and sport sensor improvements. That all said, the financial imperative IS there to deliver exotic health sensors because our populations are getting less fit by the year and high blood pressure and diabetes are mass-killers and mass consumers of funds to manage and treat them and their implications.

Take Out

There are a lot of details to mull over there.

New battery tech, new screen tech and new watch formats are the most exciting. Most likely, the excitement will come from the software improvements of watchOS 8 rather than new hardware in Apple Watch 7.

Any chance a future AW will get an in-built camera sometimes?
