Samsung Galaxy Watch4 40mm Bluetooth Smart Watch, Black (UK Version)

Product Information

Apple Watch Series 9 has a water resistance rating of 50 metres under ISO standard 22810:2010. This means that it may be used for shallow-water activities like swimming in a pool or ocean. However, Apple Watch Series 9 should not be used for scuba diving, waterskiing, or other activities involving high-velocity water or submersion below shallow depth. Water resistance is not a permanent condition and can diminish over time. For additional information, see support.apple.com/en‑gb/HT205000. The list of available colour variations have also changed, moving to a more subdued palette in the form of Midnight, Gold, Silver and Graphite, just to name a few. While the design hasn’t changed much from the Watch 4 it is still a great looking device, with slimmer bezels than the Pixel Watch and a more premium construction than any Fitbit. This model has more memory and a better chip than older Samsung watches, and swiping through menus and booting up apps is speedy. The 40mm variant we tested was compact and stylish, but the 44mm model is the preferred option for anyone with larger wrists.

This speed isn’t as noticeable as it might be on a smartphone or a laptop, but it is noticeable when compared to other smartwatches, and it allows you to use a variety of apps while the GPS features are running, for example.

So, whether you’d like to use every single feature or just the ones that’ll improve your life, you can set the timepiece to work for you. These wearables are also made for health and fitness, offering several advanced features. They come with sensors to measure movement and vibration, so they know whether you’re standing, sitting still, walking or working out. Instead, this is Wear OS 3 but with Samsung’s own skin, called One UI Watch 3, on top. It includes a variety of Samsung apps that you’ll be used to if you’ve had a Galaxy Watch before, but this is primarily Wear OS. Battery life isn’t a huge concern on the Galaxy Watch 4, but it isn’t the longest lasting smartwatch we’ve ever seen. It’ll last up to around two days with normal to intensive usage, and around three days if you’re not working out or using features like GPS. For optimal reading accuracy, your Galaxy Watch4 Classic needs to be snugly fastened to your wrist. When you are not conducting readings, you may loosen the band to provide breathing room. On balance, your watch’s band should not be fastened too tight or loose: make sure that it feels comfortable around your wrist.

As with the standard Galaxy Watch 4 though, you can often find the Watch 4 Classic at reduced prices. Samsung Galaxy Watch 4 design and display Samsung Galaxy Watch 4: Design and display There’s nothing as fancy as temperature sensors, ECG readings or automatic crash detection like the flagship models from Apple and Samsung, but that’s not surprising given the price. We like the variety of exercise modes, and the readings reflected our efforts when tested in the gym. The 40mm version comes with a smaller 247mAh cell, and we’ve yet to be able to test how well this performs. Our experience with previous Samsung smartwatches has seen a slight difference in battery life between the smaller and larger model, but you shouldn’t expect the 40mm variant to be dramatically different. The big fitness changes come in the form of a new 3-in-1 BioActive Sensor that enables the watch to monitor heart rate, blood oxygen levels and body composition. The last in that list is the only new feature, but this is the first time the sensors have been combined. For those looking for a slimmer design, the Galaxy Watch 4 offers that, with two buttons on the right-hand edge and little else to detract from its sleek looks. It comes in two models, one with a 40mm watch face and another with a 44mm body.
