The watch case houses the 1.78-inch AMOLED display, which boasts a resolution of 368 by 448 pixels for sharp text and graphics. The device earns an IP68 rating, indicating a high degree of protection against dust ingress and against the effects of temporary immersion in water. This makes it suitable for workouts, daily tasks, and exposure to the elements. The unit operates within a temperature range of 0 to 45 degrees Celsius, defining its functional environment.

Size and Practical Fit

With case dimensions of 45.2 millimetres in width, 37.2 millimetres in height, and a 10.4-millimetre depth, the RS4 Plus presents a balanced profile on the wrist. It is paired with a 20-millimetre wide strap that can be swapped for alternative styles.

Event or Professional Use

The 105 predefined workout modes cover a vast array of sports and physical activities, from running and cycling to more niche exercises, allowing for tailored tracking. The inclusion of a heart rate sensor, motion sensor, and SpO2 (blood oxygen) sensor supports 24/7 health monitoring, providing data that can inform training schedules and recovery. The IP68 rating ensures the device can withstand demanding conditions, including sweat and rain during outdoor sessions.

Everyday Home Use

Beyond dedicated workouts, the RS4 Plus functions as a daily wellness companion. The 24-hour heart rate monitoring and SpO2 tracking offer insights into general health trends.
