The Apple Watch Series 10 marks a significant leap in design and performance, blending aesthetics with cutting-edge health technology. Apple’s thinnest watch yet—only 9.7 mm thick—delivers a more comfortable wear without sacrificing functionality. Its new, larger display, available in 42 mm and 46 mm sizes, offers up to 30% more screen area, making it easier to read messages, track workouts, and navigate apps.
“In short, Apple Watch Series 10 is a meaningful upgrade focused on display, comfort, and health tech — but it may not be a must-have for all Series 9 users.”

The screen is not just bigger, but brighter from more angles, thanks to advanced OLED technology. Despite the size increase, the watch remains lightweight, especially in the aluminum and titanium variants. 
Under the hood, the S10 chip with neural engine enables faster on-device Siri and smooth performance while being energy efficient. The battery lasts up to 18 hours and charges to 80% in just 30 minutes—ideal for those on the move.
Pros compared to Series 9
- Thinner and more comfortable to wear
- Larger and brighter display
- Faster performance with new S10 chip
- On-device Siri for quicker responses
- New health features (e.g. sleep apnea alerts, water temp sensors)
- Faster charging
Cons compared to Series 9
- Higher price point
- Fewer visible design changes beyond screen and thinness
- Sleep apnea feature not yet approved in all regions
- Still no major battery life improvement beyond 18 hours
Summary
In short, Apple Watch Series 10 is a meaningful upgrade focused on display, comfort, and health tech—but it may not be a must-have for all Series 9 users.
