The RS800CX watch is the ultimate training computer for multi-sport athletes. As a heart rate monitor, the RS800CX works by first checking your daily condition, and then guiding you to the ideal training intensity for your age and fitness level. Knowing your heart rate not only helps you reach your personal fitness goal, but also improves your physical condition in general, as it’s vitally important to train at the appropriate intensity level. If you exercise too hard, you may quit before you reach the real benefit, but if you work out too leisurely, you’ll struggle to lose weight at all. The RS800CX helps overcome these problems by encouraging you to map out a complete fitness routine. The watch also displays heart rate info in several ways, including as a percentage of your maximum heart rate, as beats per minute, and within a graphical target zone indicator. And should your heart rate exceed or dip below your target zone, the RS800CX will sound an alarm that helps you return to form.

The RS800CX also offers a variety of proprietary Polar functions. The ZonePointer, for example, is an audible and visual feature on the display of your watch that shows you where your current heart rate sits within your target heart rate zone. The Polar OwnZone mode, meanwhile, provides a customized target zone for individual exercise sessions. Finally, the Polar OwnCal mode shows your energy expenditure during one exercise session, as well as your accumulated kilocalories during several exercise sessions. You can also set daily and weekly exercise goals in terms of calorie expenditure, helping you achieve both short-term and long-term goals. Other proprietary Polar functions include a Polar fitness test that measures your aerobic fitness at rest in just five minutes; a ZoneLock button that activates a target zone alarm while exercising; and an OwnOptimizer mode designed to keep you from undertraining or overtraining–a must when trying to improve overall performance.

The watch comes with the cyclist-specific CS Speed Sensor W.I.N.D. Serious athletes will appreciate in the built-in altimeter, which measures your altitude, cumulative ascent, and cumulative descent. It’s the Polar ProTrainer 5 software, however, that really helps the watch stand out. You can use the Polar ProTrainer 5 to plan your workout in advance–including creating maps and routes in conjunction with the G3 GPS sensor (sold separately)–and then transfer the settings to the RS800CX watch. Then, after training, you can analyze the results using versatile, customizable graphs to ensure a deeper understanding of your speed, exertion level, and distance. The software also includes a custom calendar that functions as a complete training log. Each time you transfer an exercise file to the program, the calendar automatically creates a diary entry with all your training data–a terrific option for athletes who want to monitor their workouts over the long term. The software even lets you export your GPS mapping routes to Google Earth, so you can view your exact training route or calculate mileage on the spot.

This version of the RS800CX comes with Polar’s CS Speed Sensor W.I.N.D., a wireless bike-mounted sensor that helps you evaluate and analyze your cycling performance. In competition cycling, time is of the essence–you simply can’t afford to fall too far behind the pack whether on the open road or in the velodrome. Thanks to the lightweight, aerodynamic CS sensor, however, you can take note of your current, average, and maximum speed readings throughout your training rides, so that you can get it right once the big race arrives. The CS communicates this speed data directly to the RS800CX, which analyzes the data in a variety of ways so that you can hone your long-term performance. The RS800CX also supports other optional W.I.N.D. sensors (sold separately) that are custom built for various training needs. The S3 Stride Sensor, for example, measures every stride you take while running, helping you perform better in competitive situations, while the aforementioned G3 GPS sensor accurately tracks your movement during less-traveled sports, such as canoeing, mountain biking, rowing, or Nordic skiing. With the purchase of all three W.I.N.D. sensors, your RS800CX will become an extremely versatile multi-sport training computer.

Other watch features include several recording options to help track your heart rate, calorie expenditure, distance, and more and save it in an exercise file (with 99 total files); water resistance to 50 meters; a Polar WebLink connection for transferring exercise data from your wrist unit to a computer; a 12/24-hour clock with a day/week indicator; a built-in backlight; an alarm with a snooze; and a low battery indicator. Sporting an attractive silver housing, the watch carries a two-year warranty.
