With the Galaxy Watch9 and the Galaxy Watch Ultra2, Samsung is expanding its smartwatch offering. The new generation includes five variants for everyday use, sports, and diving.
With Samsung's new smartwatches, the decision starts with the size. The Galaxy Watch9 is available in 40 or 44 millimeters, and each with 4G or without a SIM. The Galaxy Watch Ultra2 is significantly larger at 47 millimeters and is also designed for diving.
Galaxy Watch9: 40 or 44 millimeters
The two sizes differ mainly in display, battery, and weight. The smaller model has an aluminum case measuring 40.4 × 42.7 millimeters and weighs 31.5 grams without the strap. Its OLED display measures 1.34 inches and has a resolution of 438 × 438 pixels.
The larger version measures 43.7 × 46 millimeters and weighs 34 grams. Its 1.47-inch display offers 480 × 480 pixels. According to Samsung, both versions achieve a maximum brightness of 3000 nits.
The small model contains a 390 milliampere-hour battery. The 44-millimeter version has 445 milliampere-hours. Both watches can be charged wirelessly via the included charging station. Samsung does not provide specific information on battery life.
The Galaxy Watch9 is available in Cream (White), Graphite, and Silver. The aluminum case is protected against dust and water according to IP68. Samsung also states a water resistance of five ATM, so you can wear it while swimming. It is not intended for diving.
With 4G or without SIM
Both sizes are available with 4G or without a SIM. The models without a SIM connect to your Android smartphone via Bluetooth or access a known Wi-Fi network.
The 4G versions establish a mobile connection themselves via a compatible eSIM. This allows you to leave your smartphone at home while running, for example, and still receive calls or messages. For this, you need a suitable plan from your mobile provider.
Models of the same size do not differ in display, storage, sensors, or processor.
Sensors for training and health
All variants are powered by the Snapdragon Wear Elite. They also come with two gigabytes of RAM and 32 gigabytes of internal storage. Samsung uses Wear OS 7 with One UI 9 Watch as the operating system. The watch requires a smartphone with at least Android 13 and 1.5 gigabytes of RAM.
Features include sensors for heart rate, skin temperature, and blood oxygen. The watch also collects data on body composition via bioelectrical impedance analysis.
The Samsung Health app analyzes the measurements. The Energy Score summarizes sleep, activity, and heart rate data, among other things. In addition, there is an analysis of vascular stress during sleep and a running coach with customized training plans. The watch can also indicate possible signs of sleep apnea.
For positioning, the Watch9 uses dual-frequency GPS. It supports GPS, Glonass, Beidou, and Galileo.
Galaxy Watch Ultra2 for outdoor sports and diving
The Galaxy Watch Ultra2 has a 47.1 × 47.4 millimeter titanium case and weighs 61.5 grams. Its 1.5-inch OLED display reaches up to 5000 nits, according to Samsung, and should therefore remain readable even in bright ambient light. Samsung has installed the Snapdragon Wear Elite, two gigabytes of RAM, and 64 gigabytes of internal storage in this model.
The battery has a capacity of 784 milliampere-hours and is said to last up to 60 hours, according to Samsung. For use in water, the case is designed for up to ten ATM. In addition, the watch meets the EN 13319 standard for diving instruments and is suitable for dives up to 40 meters.
Samsung offers the Galaxy Watch Ultra2 exclusively with 4G. For the mobile connection, you need a compatible eSIM and a suitable plan.
