Sorry, this is my first time here and I messed up the pics. This should get it right.

The pictures below (taken from the Heuer stopwatches page on this site), give a good idea of how it looks.

Its buttons and crown resemble those in this picture, although there is another button on the right of the crown, and the top of the crown is flat.





Its case and face are like those in the next picture, except there are 100 divisions in the outer ring, there is no hour counter, and the split hand is black.
