I got a used, but in
good shape Lungman. They are hard to get on the one hand, but on the other
they are not very wanted. I guess it's for the pretty insecure Heat Rate
measurement and it's asymmetrical shape. It has also a Stopwatch with 30 lap
memory on board, so it was designed to be a runners watch, as you also can
see on the picture of an ostrich on the back.
