Don’t weigh yourself down with more tech. Suunto’s new 3 series uses the GPS you’re already carrying (your phone) to tell you more about how you train. GPS data gives you access to your distance covered, speed metrics and more. The free Suunto app lets your smartphone communicate with your watch, and it provides access to more than just a GPS signal – it sends notifications, reminders and messages right to your watch. The 3 Fitness All Black features an optical heart rate monitor that takes pulse information straight off your wrist, doing away with the need to wear a finicky chest strap. As it learns your current activity level, the 3 Fitness All Black provides you with a personalized training plan that offers live updates, letting you know when to go harder or to slow down. It also adapts if you miss a workout, or if you crush it a bit harder than you have before. If a training plan isn’t your style, the 3 series is preloaded with 70 different activity profiles – there's one for everyone, unless you're into something really niche. When you're not training, the 3 Fitness All Black's activity tracker functionality keeps track of your steps and calories, and monitors the quality of your sleep at night. It then takes all of your data into consideration when calculating recovery times and tracking progress.
- Equipped with Valencell’s optical heart rate monitor (version 1.2), which provides more reliable constant heart rate data, and allows you to train without a chest strap. This sensor even works while swimming!
