The weight difference between the models is not insignificant, but the robust construction ensures comfort throughout the day. The watch is water-resistant up to 50 meters (IP68) and passes MIL-STD-810G durability tests, meaning you can wear it while swimming and during more demanding daily routines. The straps use standard 20mm/22mm connectors, making replacements easy when you want to change your style without additional costs or trips to a service center. In short, the Galaxy Watch3 is engineered for everyday use but also for those who seek a touch more class in its finishing.
Hardware and Performance: What Lies Beneath the Premium Casing
Processor, Memory, and Storage
Under the hood lies the Exynos 9110 (10nm) dual-core CPU, offering responsive interaction thanks to 1GB of RAM and 8GB of internal storage. While one might expect a larger capacity in more modern wearables, it’s sufficient for everyday tasks, health tracking, receiving notifications, and running a few applications. An added benefit is the ability to install smaller apps designed for the Wear OS/Tizen ecosystem, enabling some functionalities to be used independently without constant phone connectivity.
Display, Battery, and Charging
The 45mm model is equipped with a 340 mAh battery, while the 41mm version uses a 247 mAh unit. This detail is crucial for the device’s longevity—the larger battery in the 45mm version typically allows for longer periods between charges, but its smaller counterpart can also be appealing for those who prioritize wrist comfort. Charging occurs via a magnetic cradle; the watch isn’t compatible with standard Qi chargers without a specific magnetic adapter, which is less of an issue in practice given the included full kit. In daily use, with regular usage (heart rate monitoring, notifications, occasional GPS and workouts), expected battery life usually ranges from 2-3 days, varying depending on the intensity of Always-on display and GPS tracking usage.
Sensors and Connectivity
Sensors include the standard accelerometer, gyroscope, barometer, and heart rate sensor. Additionally, there’s NFC for Samsung Pay, significantly simplifying quick payments on the go. LTE connectivity is also available (on select models), making the watch partially autonomous from the phone, but realistically, for a complete experience, a reliable smartphone connection is still expected. It’s noteworthy that potential versions with ECG (electrocardiogram) monitoring are not universally available; their availability depends on the market and regulatory approval, so expect concrete news to be publicly announced and rolled out over time in major regions.
