Very very light compared to a Suunto Ambit (one does not feel it), for much less against fashion. As much as we might consider wearing the Suunto Ambit in a professional environment, as this is considered a toy. Come to think, the Orange + White helps.
Garmin Connect is light years ahead of Movescount, ergonomics, reactivity etc ... And the possibility of making transfers directly WiFi is a treat. I have not used the watch with my phone (it is an Android, unsupported by Garmin).
This is not really a multisport watch as the Ambit .. The forerunner can be used for other activities such as cycling, but it is less versatile than the Ambit and does not work with all types of sensor .
