Apple Watch 3 vs Apple Watch 2

The recent inaugural event at the Steve Jobs Theatre saw Apple unveil the bulk of its product line-up for the year ahead. Among the new devices announced were the iPhone X, iPhone 8 and 8 Plus, the Apple TV 4K, plus a significant step forward for the Apple Watch.

In this article we look at how the newest version of Apple's timepiece compares to its predecessor, and whether you should be looking to upgrade from the Apple Watch Series 2 to the Apple Watch Series 3.

Apple Watch 3 release date

The Apple Watch 3 was released on September 22. As usual a number of configurations are available, but the cheapest non-cellular models cost £329 (US $329) for the smaller 38mm version, and £359 ($359) for the 42mm.

If you want the LTE equipped models - and as that's one of the biggest selling points of the Apple Watch 3 we're guessing you might - then the starting prices are a little higher, with the 38mm costing £399 ($399) and the 42mm coming in at £429 ($429).

Apple has retired the Apple Watch 2 now, so buying one will require sourcing other retailers who are selling off older stock.

The Series 1 has survived the cull, though, and at £249 ($249) for the 38mm and £279 ($279) for the 42mm, it seems a good deal for those who aren't too fussed about GPS tracking.

What's new in the Apple Watch 3?

LTE capabilities

The most obvious advance offered by the latest model is that of LTE cellular compatibility on the GPS + Cellular variants. This is quite a big deal as it moves the watch closer to being a standalone device - but only in your home country, because they do not support roaming.

The Apple Watch 2 brought built-in GPS, allowing wearers to go for a run without their iPhone and still record the data. This would then be transferred to the iPhone once the two were reunited.

The Apple Watch 3 takes this independence a step further by including a rather clever electronic SIM, which shares your iPhone's number, so the device can connect to the internet over 3G or 4G signals.

The shared number also means you'll be able to receive calls on the Apple Watch 3, as well as receive messages and notifications, all while in the swimming pool, gym, or anywhere that iPhones fear to tread.

Having internet access will enable you to stream songs from Apple Music on the new device, which can be played back on your Apple AirPod headphones, or other compatible Bluetooth headsets.

Of course, these features will involve data usage. The one thing that has been confirmed is that the Apple Watch 3 will need to be on the same carrier as your iPhone, and at the moment EE is the only choice available in the UK.

You can register your interest online with EE. The company has offered further contract information:

"The Apple Watch Series 3 Cellular standard 38mm version is available free on a £25 per month Smart Watch plan, including unlimited data. The standard 42mm version has a one off upfront cost of £29.99, the 38mm steel version has a one off upfront cost of £129.99 and the 42mm steel version has a one off upfront cost of £159.99 - all are available on the £25 per month Smart Watch plan."

Improved hardware

Internally the Apple Watch 3 has seen some significant hardware upgrades, with the new dual-core S3 processor being claimed to offer a 70 percent improvement in speed over the Apple Watch 2.

Wi-Fi and Bluetooth connectivity also received a boost, thanks to the introduction of the W2 wireless chip. Apple states this will improve Wi-Fi performance by around 85 percent, while halving the energy demands.

A new barometric altimeter has also been included, which can sense when you're going up and down stairs. This is great news for those who track their steps and have previously been short-changed for their efforts.

Finally, Siri can talk to you on the Apple Watch 3, as well as being accessible away from the companion iPhone.

Is it bigger than the Apple Watch 2?

With all these hardware advances, it would be reasonable to expect that the casing could also show signs of growth. But, in a feat of engineering that should be applauded, Apple has managed to keep the chassis almost exactly the same.

To achieve this the design team turned the screen itself into the LTE antenna. They really do have some clever people over in Cupertino.

Apple did make one change to the casing, though, and that was to put a red dot at the end of the Crown. As far as we can tell this is purely an aesthetic choice, but it does mean that people will be able to tell at a glance that you're wearing the latest and greatest.

(The red Digital Crown indicates cellular models. The GPS-only versions of the Series 3 don't have this.)

Surely all of these extra features will drain the battery faster?

Again, a perfectly sensible and valid assumption. Therefore, it came as quite a surprise when Apple revealed that, thanks to the various energy efficiencies brought by the new chips, the Apple Watch 3 will return the same battery life as the Apple Watch 2.

Official figures are 18 hours when a mixture of Wi-Fi and LTE are used. We can't confirm this yet, but it's something you can be sure we'll thoroughly test in our upcoming Apple Watch 3 review.


With the Apple Watch Series 3 it does feel like Apple has finally released a wearable that realises its potential. The LTE-equipped models have a freedom that is truly useful, especially in terms of health and fitness, but also for conveniently staying in touch without the need for your iPhone. 

Not only that, but to increase performance and features, all without sacrificing battery life or size, is truly impressive.

If you can find a good deal on the Apple Watch 2 then it's still a very good device, but the newer models are a big step forward for the platform and would definitely be the ones we'd choose.
