Weems & Plath Night Watch Tide Clock

 

Photo-luminescent dials combined with corrosion resistant, black epoxy coated aluminum cases. The clock has a second hand to ensure proper movement, plus a tide indicator hand which is calibrated to the Atlantic lunar tide cycle. (Note: The clock will work for other tidal bodies of water but will need to be re-set more frequently.)

 

It uses a AA battery (included).
