Best Apple Watch deals To make matters simple, we’ve compared the Apple Watch Series 6 to the Watch SE and Watch Series 3 here so you can see exactly what the differences and similarities are, whether you’re looking to upgrade or take the smartwatch plunge. For the avoidance of doubt, the Series 6 is very similar to the now-gone Series 5 with a few new features. squirrel_widget_2670420 Design Series 3: 11.4mm thick,5ATM waterproof Watch SE: 10.7mm thick,5ATM waterproof, Compass Series 6: 10.7mm thick,5ATM waterproof, Compass, Electrical heart rate sensor, Blood oxygen sensor Straps compatible across all models All the Apple Watch models being compared here feature a solid rectangular body with the Digital Crown and separate button on the right, along with a speaker and microphone on the left. They are all swim-proof up to 50-metres and they all have a heart rate monitor positioned on the underside of the watch body, along with the release buttons for switching out the straps. There are some differences between the Series 3, SE and Series 6 though. Firstly, the Series 3 is slightly thicker than the Series 6 and SE model. Secondly, in the case of the Series 6 (and Series 4 and 5), the Digital Crown has an electrical heart rate sensor built into it, which is in addition to the optical heart rate sensor on the underside of the watch. The Watch Series 6 also has a blood oxygen sensor, which is the main differentiating factor between it and the Series 5 and 4. Display Series 3: OLED Retina display with Force Touch Watch SE: LTPO OLED Retina display with Force Touch Series 6: LTPO OLED Always-On Retina display with Force Touch All the Apple Watch models being compared here have OLED Retina displays with Force Touch built into them, allowing for different functions depending on the force with which you press. The Series 6 and the Watch SE have a 30 per cent larger display than the Series 3 with rounded edges however, making full use of the space available and resulting in a bolder design. The larger display ratio makes the Series 6 and Watch SE (as well as the Series 4 and 5) look quite different from the Series 3 despite a similar design overall. In addition to the display increase, the Apple Watch Series 6 also offers an Always-On Retina display, which the Watch SE and Series 3 don’t. The Always-On display means you don’t have to raise your wrist to wake the display up, with the screen always visible. A raise of the wrist or a tap on the display will brighten the Series 6 (and Series 5) display instead.
