Updated October 2026.
The Apple Watch Series 10 introduced a thinner case, larger displays and faster charging. It remains a useful smartwatch for iPhone owners, although newer models now sit above it in Apple’s range. This refreshed review corrects the original sizes, battery figures and health claims.
Apple Watch Series 10 Review: Key Details
- Introduced: September 2024
- Case sizes: 42mm and 46mm
- Case materials: Aluminium or titanium
- Display: Always On Retina LTPO3 OLED
- Chip: S10 SiP with 64GB storage
- Original UAE launch price: From AED 1,599
- Battery claim: Up to 18 hours, or up to 36 hours in Low Power Mode
The Series 10 has been superseded in Apple’s current range. New stock may still appear through retailers, while refurbished and used examples are common. Prices should be assessed against battery condition, case material and cellular capability.
Design, Sizes and Comfort
The original article listed 41mm and 45mm sizes. Those figures apply to earlier generations. Series 10 uses 42mm and 46mm cases, and both are 9.7mm thick.
The wider angle OLED display is easier to read from the side. It reaches up to 2,000 nits and can dim to 1 nit. Aluminium versions use Ion X front glass, while titanium versions use sapphire crystal.
Size is a personal choice. The 42mm case suits smaller wrists and feels lighter. The 46mm version provides more screen area. Trying both sizes before purchase is worthwhile.
Health and Fitness Features
Series 10 includes heart rate monitoring, ECG support, temperature sensing, sleep stages and activity tracking. It can also support sleep apnoea notifications in eligible regions for eligible users. Availability varies by country and software version.
The original review incorrectly claimed that the watch tracks blood glucose. Apple Watch Series 10 does not provide direct blood glucose measurement. Health readings are not a substitute for professional medical advice.
Fitness tracking covers common workouts, pace, heart rate zones and training metrics. The watch is water resistant to 50 metres and includes a depth gauge for shallow recreational activities. It is not designed as a specialist dive computer.
Performance and Daily Use
The S10 chip keeps navigation and app launches responsive. The Double Tap gesture can handle selected actions without touching the screen. Cellular models can make calls, receive messages and use data without an iPhone nearby, subject to carrier support and an active plan.
Series 10 works best inside Apple’s ecosystem. Notifications, Apple Pay, Maps and workout data connect smoothly with an iPhone. Android phones are not supported.
Battery Life and Charging
The original 48 hour claim was inaccurate. Apple rates Series 10 for up to 18 hours of normal use. Low Power Mode can extend that to 36 hours. Real results depend on workouts, cellular use, display settings and battery condition.
Fast charging is a practical advantage. Apple says the battery can reach about 80 percent in 30 minutes with compatible equipment. A short charge before bed can make sleep tracking easier.

Frequently Asked Questions
Does Apple Watch Series 10 measure blood glucose?
No. It does not offer direct blood glucose measurement.
How long does the battery last?
Apple rates it for up to 18 hours in normal use and up to 36 hours in Low Power Mode.
Can Series 10 work without an iPhone nearby?
A GPS plus Cellular model can use supported services away from an iPhone. It needs carrier support and an active plan.
The Brief Review Verdict
Apple Watch Series 10 remains a polished smartwatch for iPhone users. Its thin case, larger display and fast charging are the main strengths. Battery life is still a daily consideration, and it is not a glucose monitor. At the right second hand or retailer price, it can be a sensible alternative to a newer model.
