Maximum Harbormaster Tide Clock

The Harbormaster is a tide clock with a patented quartz movement. Powered by a single AA battery, it tracks according to the average time between lunar high tides (12 hrs, 25 min).

Fluctuations in conditions, location and the distance of the moon from earth can affect this average. However, over a lunar month, the Harbormaster will provide a practical indication of local tides in a traditional brass dial.
