The Weather Watch Pro

It’s big, but then again it’s the Pro version…
“The Weather Watch Pro uses a Swiss-made impeller for current, average, and maximum windspeed. One of the impeller fins is magnetized, highlighted in green and always points North. This allows you to mechanically determine wind direction. The display is Backlit and the unit is water resistant. Weather Watch Pro can be detached from the wrist strap and worn on a lanyard.”
