Today only, save 42 percent on a water-resistant Activité Steel activity tracking watch from Withings. The body is made of stainless steel and it has a silicone strap that makes it comfortable to wear while working out. The watch measures your steps, swimming distance, running distance, and how many calories you've burned. It also analyzes your sleep patterns. Its big strengths, though, are the sophisticated look (it comes in two colors) and its use of a standard watch battery, which means you'll get up to 8 months of battery life. You can get it today for $75.
