I am already in possession of two sports watches, the Garmin Running Watch Forerunner to a 620 HR Incl. Premium RF chest Run and the Nike + SportWatch GPS powered by TomTom Running Watch with shoe sensor, model 2012, so a bit dated. First, the pleasant appearance is striking, although it still looks a little cumbersome. The workmanship is good and the reconciliation between black and red, I find it very successful. Is supplied in small handy box in which there is for the bike except the clock, even a bracelet, charger, manual and mounting. The included manual is equipped with the most important points. The manual, as well as key functions also obtained via the website of TomTom, much is explained here in detail and easily understandable in videos. The initial setup is quick and easy, only the multifunction button on the everything is controlled, is getting used to at first. The entire operation takes place only on this button and the adjustment menu is clearly laid out, the condition slightly overall and even for novices to understand immediately. The clock wears comfortable, where the bracelet is slightly stretchy and therefore itself is not disturbing at close Create. It must be used while running, biking and swimming, the latter but without heart rate monitor. The GPS signal is found even faster than with the Garmin and was significantly faster than the Nike, which is much older. The display is readable even in direct sunlight without any problem, and the font so large that they can be read also in strenuous direct state and during running. The display is limited to three pieces of information (the selection is quite varied, however), so you should be in front of the run make about what information you need ideas. There is no key lock, but with a light, but this comes only from a corner and just sufficient so. The heart rate monitor because of the skin perfusion is at fixed stop quite well, from time to time I have time discrepancies, but the technology is more pleasant than a chest, only slightly less accurate. Currently appearing relatively many firmware updates that information as obtained on the specified e-mail address upon registration. The online portal, and the app for the iPhone (from 4S) are sufficient, but still room for improvement. The only thing that bothers me is the battery, which is not enough at my clock, without any activity by 24 hours. Conclusion: Truly an alternative to my Garmin Running Watch, which has grown to me in no time to the heart, especially the Herzfequenzmesser enough for me in this form without additional chest strap from. However, because the battery only three stars because of not enough.
