Apple Watch Series 9 41mm GPS vs Apple Watch Series 10 46mm Cellular

Both are current Apple Watch models with the same 4.8 rating, so the choice comes down to size, connectivity and sensors. The Series 10 46mm is the bigger, newer watch with an S10 chip, a larger 416x496 display, cellular built in, sleep tracking and skin temperature sensing. The Series 9 41mm is the smaller, lighter option with an S9 chip, a 352x430 screen and GPS only, so it needs your iPhone nearby for calls. Buy the Series 10 if you want a larger screen, standalone cellular and the newest chip; buy the Series 9 41mm if a smaller, lighter watch on your wrist matters more and you always carry your phone.

• Choose the Apple Watch Series 9 41mm if you have a smaller wrist, want the lightest fit, and always keep your iPhone within range.
• Choose the Apple Watch Series 10 46mm if you want the bigger screen, built-in cellular for calls without your phone, and the newer S10 chip.
