Whether you’re summiting a mountain, relaxing at the campsite, or just strolling downtown, the Suunto Core Ultimate has you covered. Loaded with functionality, it features a built-in barometer to measure atmospheric pressure, an altimeter to measure altitude, a compass for navigation, and a series of weather functions to alert you in case of a storm or other inclement conditions. Also unique to the Core? The stainless steel top ring and luminescent details make for greater durability and visibility. Plus, this watch has a built-in stopwatch and alarm, and it will tell you when the sun rises and sets. At 49 millimeters, the case is large enough to see in low-visibility conditions like snow and rain. But, while relatively large, the watch weighs less than 2.5 ounces, so it won’t bog you down during physical activity.
