Complete Description: This part appears to act as a coupling between the pusher in the center of the crown, and the chronograph operating lever. It is not fitted to every caliber 19.73 movement.

Caliber 19.73 was manufactured for 15 or 20 years starting about 1898. While the basic caliber remained the same, there were variations over the years.

Unable to find either a Longines factory part number or an official part description.
