Based on our testing in the full reviews — full review of Apple Watch SE 3, full review of OnePlus Watch 3, and full review of Samsung Galaxy Watch Ultra — the design philosophies differ significantly.
Design and Build
The Apple Watch SE 3 prioritizes comfort with lightweight aluminum construction and comfortable bands suitable for all-day and overnight wear. By comparison, both the OnePlus Watch 3 and Samsung Galaxy Watch Ultra utilize premium titanium construction, with the OnePlus adding sapphire crystal for flagship-level build quality at a mid-premium price. The Samsung model carries military-grade durability certifications but its large 47mm case size may feel bulky on users with smaller wrists.
While the Apple Watch SE 3 focuses on lightweight practicality, the competing Android watches deliver more robust premium builds that justify their higher prices. The OnePlus straps, while comfortable, attract dust and lint more readily than alternatives, whereas the Samsung’s titanium design excels in rugged scenarios.
Performance and Features
The Apple Watch SE 3 impresses with its S10 chip that delivers flagship-level speed and responsiveness exceeding expectations at this price, alongside comprehensive fitness tracking featuring accurate GPS and heart rate monitoring that rivals more expensive models. However, its approximately 18-hour battery life requires daily charging for most users, it lacks an always-on display, and it omits advanced health features like ECG, blood oxygen monitoring, temperature-based cycle tracking, and sleep apnea detection.
The OnePlus Watch 3 and Samsung Galaxy Watch Ultra both deliver exceptional battery life that far surpasses the Apple, with the OnePlus reaching up to 14 days of typical use and the Samsung providing multi-day performance that outperforms most competitors. Both offer advanced AI health coaching with personalized insights, though some advanced metrics on the OnePlus are locked behind a subscription after the trial period, and certain Samsung features deliver full functionality only when paired with a Samsung smartphone. The OnePlus provides class-leading performance with smooth Wear OS 5 operation, rapid app launches, and highly accurate dual-band GPS, while the Samsung excels with its latest Exynos chipset, optimized Wear OS 6, and a bright display that performs excellently in direct sunlight and low light conditions.
The Apple Watch SE 3 delivers seamless integration with iPhone that Android alternatives cannot match, but the Wear OS ecosystem on the OnePlus and Samsung still lags behind watchOS in app quantity and optimization. The Samsung’s always-on display can drain battery faster than expected during heavy usage, while the OnePlus lacks cellular LTE connectivity, requiring a nearby phone for full functionality.
Pricing and Value
At $189.99, the Apple Watch SE 3 delivers the strongest value with its 89/100 overall score, five years of watchOS updates for excellent long-term value and security, and performance that exceeds expectations at this price point. The OnePlus Watch 3 at $249.99 and Samsung Galaxy Watch Ultra at $239.95 both command mid-premium pricing that reflects their titanium builds and superior multi-day battery life, yet the OnePlus is limited by three years of software updates and subscription-locked health metrics.
The Samsung offers exceptional durability and display performance for its $239.95 price, making it a worthwhile investment for users who need ruggedness, though its premium positioning makes the Apple Watch SE 3 the more accessible daily driver for most buyers. Overall, the Apple provides the best long-term value for iPhone users, while the Android options suit those willing to pay more for battery endurance and premium materials.
