Survey Chronometer with Bond's make and break circuit (now sadly removed). The chronometer was purchased in a Hamilton box that was sold to someone in need of a box for his model 21. The pot number also does not match the movement number and the movement is largely unnumbered.

Still with all its weaknesses, it is quite interesting.

It resides in a box that came from Russia with my Dent Staple Balance chronometer. That generic box provides a comfortable home for Mr. Bond.
