great part of the bezel has broduit

This is a very good watch, light, compatible Windows and OSX, the heart rate monitor flawless operation.
For the GPS signal is very correct (exact).
The signal can be found, when you start looking in a few seconds up to 15 minutes of time (overcast) ... (It was therefore all the time to stretch ;-).
I have no comparison to other GPS watches. Maybe this is normal.

This does not work very well, it is the bezel technique. As soon as there is a bit humid (rain sweating) the bezel (it is not a touch screen) does not respond, or it changes in another mode (time, GPS settings).
For me, the next time it'd be a watch Garmin same quality, without bezel, so classic ;-).
