You do need to get the gesture right though, and too often we found that Siri wasn’t in fact listening, which turns you off from using a voice assistant instantly, especially if other people can see you. Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB‑C Cable. Testing conducted by Apple in August 2022 using pre‑production Apple Watch Ultra (GPS + Cellular) paired with an iPhone; all devices tested with pre‑release software, Apple Watch Magnetic Fast Charging USB‑C Cable (Model A2515) and Apple 20W USB‑C Power Adapter (Model A2305). Charge time varies with region, settings and environmental factors; actual results will vary.

The Series 6 also features Apple's signature digital crown on the top right side. Press this button to return to the watch face; press and hold it to talk to Siri; or turn it to scroll, zoom, or adjust. Placing the Watch higher up our arm helped with the accuracy (as it’s easier for the sensor to read the pulse through the skin here), but it wasn’t comfortable and fell forwards eventually.

In the box with the watch, Apple includes a charging cable, but you don't get a USB power adapter. Apple says it made this decision to help the environment, and it will have the same impact as eliminating 50,000 cars from the roads. Design The Series 6 is light and comfortable on my wrist, even when I wear it to bed. The 40mm and 44mm aluminum models weigh 1.07 ounces and 1.28 ounces, respectively, without the strap. The stainless steel models are the heaviest at 1.40 ounces and 1.66 ounces, and the titanium models weigh 1.22 ounces and 1.45 ounces. One nice improvement is that the Series 6 charges faster than the Series 5, which takes around two hours to fully charge. The Series 6 charges to 80 percent in about an hour and to 100 percent in 90 minutes.

The display, using OLED technology, is as bright and clear as ever – we didn’t notice any extra brightness outside, despite the claims made by Apple, but equally we never struggled to read the display, thanks to the rich colors and good contrast ratios.

Charge times are from 0–80% and 0–100% using the included Apple Watch Magnetic Fast Charging USB‑C Cable.

Charge time varies with region, settings and environmental factors; actual results will vary. In ‘normal’ use, that is with the SPO2 sensor and always-on display firing, the Watch 6 will last 20% less than the Watch SE in the same usage conditions, although of course you can always turn these features off– you won’t be getting the same functionality, but it is a way to get the best battery life on any Apple Watch.
