Ranked #2 in Best Smartwatches
Apple Watch Series 11
$329as of Jul 6

The Apple Watch Series 11 offers a refined iteration of its predecessor with notable improvements in display brightness and performance thanks to the S9 SiP chip. PCMag's Andrew Gebhart notes it's a 'small but meaningful step forward' without dramatic redesigns. CNET's reviewer calls it a 'goldilocks pick' but suggests it's becoming harder to recommend over newer models. The watch maintains its strong position in health monitoring with enhanced ECG capabilities and always-on display improvements, though it lacks major innovations that would distinguish it from previous generations.

Strengths
  • Improved brightness with up to 2,000 nits peak brightness for better visibility in sunlight
  • Enhanced always-on display functionality with improved readability
  • Faster S9 SiP chip delivering better performance and efficiency
Watch-outs
  • No significant design changes from Series 10
  • Still lacks standalone cellular connectivity in entry-level models
OnePlus Watch 3
Ranked #3 in Best Smartwatches
OnePlus Watch 3

The OnePlus Watch 3 delivers exceptional battery life with its 500 mAh capacity and dual-engine architecture, making it one of the most reliable Wear OS smartwatches. CNET praised its impressive endurance, while GSMArena highlighted its durable design with MIL-STD-810H certification and IP68 rating. The 1.5-inch LTPO AMOLED display offers excellent brightness and resolution. However, reviewers noted the charging cradle's alignment requirements and subpar audio quality during calls. This watch is ideal for users seeking long battery life and robust build quality, though those wanting eSIM functionality or better call quality should consider alternatives.

Strengths
  • Impressive battery life with 23% increase in capacity to 500 mAh
  • Durable build with MIL-STD-810H certification and IP68/5ATM ratings
  • Large 1.5-inch LTPO AMOLED display with 466x466px resolution and 2,200 nits brightness
Watch-outs
  • Charging cradle requires precise alignment
  • Sound quality during calls is tinny with average microphone performance
  • No eSIM support despite Bluetooth and Wi-Fi connectivity

How they stack up

Apple Watch Series 11

The Apple Watch Series 11 improves upon its predecessor with a faster S9 chip and enhanced display brightness, but unlike the Apple Watch Ultra 2, it lacks rugged durability and specialized outdoor features. Compared to the Apple Watch SE, it offers more advanced health monitoring and a premium feel, though it doesn't provide the budget-friendly value that the SE delivers. It's a refined upgrade for existing Apple Watch users but doesn't break new ground in terms of design or functionality.

OnePlus Watch 3

The OnePlus Watch 3 excels in battery life and durability, surpassing the Apple Watch Series 11 and Apple Watch SE in both areas, but it lacks the advanced health sensors and app ecosystem of Apple's offerings. Compared to the Garmin Venu 3, it offers better display resolution and a more comfortable fit, though it doesn't match the Garmin's sleep tracking or third-party app support. It's a strong contender for users who prioritize endurance and build quality over smart features.
