The Apple Watch Series 4 has been essentially redesigned and re-engineered to assist you to remain more active, healthier and more connected. The first thing about Series 4 you will notice is its face. Apple purged the thick bezels around the display of the watch. You have 40 mm and 44 mm versions instead of 38 mm and 42 mm heights, with larger screens that touch the edges.

The whole underside of the series 4 is now ceramic as part of the back changes, instead of just the heart rate sensor. This is good when it comes to making it as non-comedogenic as possible. The Digital Crown was thinned a bit and now has haptic responses when you spin it, with a mild vibration slightly on your finger.


Both models of the Series 4 are slightly larger than previous models. There is a 368 x 448 display on the 44 mm series, with the 40 mm packing 324 x 394 pixels. Both series 4 models use OLED displays, offering Force Touch and 1000 nits of brightness. The touchscreen of the series 4 models is sharp with vibrant colors. The font is readable, and it is easy to see and interact with icons.


Apple Watch Series 4 packs the S4, a new 64-bit dual-core CPU and a new GPU that doubles the watch performance. Using less energy, a faster Bluetooth 5.0 that can send and receive information faster was added and Apps load faster. The series 4 also features auto-detect workouts, new yoga + hiking workouts, and more advanced features for runners such as alerts for cadence and pace.

With the Walkie-Talkie feature, Apple Series 4 watches can excellently execute phone calls and messages. These smartwatches can also be used with Apple Music and Apple Podcasts. There are also new ways to use your favorite Siri Shortcuts apps right on your wrist.

The series 4 fall detection is a feature that is automatically switched on for older folk if your profile informs Apple that you’re over 65. This feature analyzes and identifies a fall impact and then sends its user an alert after a fall, which can be dismissed or used to initiate a call to emergency services. If you do not respond within a minute, an SOS call to emergency services is made automatically. Lastly, the Series 4 features a new electrical heart sensor consisting of electrodes integrated into the Digital Crown and on the back of the watch.


The Series 4 really is the best Apple Watch, and also the best smartwatch on the market with the specs, new design, and new hardware. This a smartwatch for everyone.
