I looked at the clock gained as a running companion to have a Pace-control in training. The clock has cost about 230 and has measured off the track length and the speed of the heart rate with a chest strap. Unfortunately, the clock does not function cards. (Only when transmitting in the app) As a comparison, I have added myself free for my smartphone a run-app (Runtastic) with the same functionality. The Garmin-clock has me as opposed to the app - demonstrated absolutely no advantage, so that the high purchase price was absolutely not my value - up to wearing the arm. I think if the Deployment of Smart Watches establishes itself - on which then the running apps can be installed - manufacturers of such GPS watches will find it difficult. The GPS measurement seemed in "wooded areas" as being unstable, this and the high price cause the review with 3 stars.
