Thats the Suunto Gem compass. They also have the comet which has a bit bigger ruler and a thermometer.
If the bezel is like the clipper, its not smooth, it clicks into place at every point marked around the bezel.
I havent seen either the Gem or Comet, but I have a couple of clippers and they are a good little compass.
