WWI Dogtag watch fob with attached profile

This is an interesting watch fob with a WWI dogtag attached. measures 51/2 inches overall. Dogtag has the the following engraving: "E.P. Lawsing,
12-15-17, 10-16-88, U.S.N.R.F." on one side and a thumbprint on the other side. The women's face looks like it is a repro of some famous profile (I could be wrong here) and the pocket watch connection is engraved with "9C." 9 carat gold. Any info on this item would be appreciated, it is quite unique... Thanks ChuckG Marion, MA
