The M71ti is set in a fashionable titanium case. Great for the person looking for some extra guidance with their workouts and a stylish time piece all in one. The OwnCal™ feature counts the calories and fat that you burn based on your effort level, not the treadmills. OwnZone™ takes the guess work out of finding your personalized target zone. The M71ti will determine your target zone based on how your body feels for that specific day, preventing you from over-exercising and possible injury.
