The newest version of the Timex Health Tracker watch features a Walk Sensor and Diet Diary to help take the guesswork out of diet and exercise. The watch automatically records steps, distance, calories burned and active time throughout the day by sensing natural swinging motions of your arm -- and it can also discretely store the number of calories or units consumed, eliminating the need for a pen and journal at every meal. It also includes an intuitive Workout Mode with pace and distance, Seven-Day Activity Log, Countdown Timer, Alarms, 50 meter water-resistance and night-light. (Available in May 2011.)
