Interesting clock housed in a glass dome with bronze base.  The clock is similar to a pocket watch movement but is fixed onto a base and then covered with a glass dome - the dome can be unscrewed and removed.  The front of the clock face bears the words CLEMENT FRERES 1880 & the reverse has the writing MADE FOR ROYAL NAVY LONDON.  The bottom of the clock has a winder.  It overall stands 4.5" high & 3" wide.
