Harbormaster is an east coast tide clock with a patented quartz movement. Powered by a single AA battery (included), Harbormaster tracks according to the average time between lunar high tides in the Atlantic Ocean (12 hrs, 25 min.). Fluctuations in conditions, location and the distance of the Moon from Earth can effect this average. However, over a lunar month, Harbormaster tide clock will provide a practical indication of local tides. PVD cases are ideal for instruments that do not receive regular cleaning and/or are exposed to harsh salt air environments. The process starts with a solid brass case. The case is then chrome plated and treated with a Titanium finishing coat that has been colored to re-create the beautiful brass finish you expect from Maximum. This process results in an incredible tarnish resistance for many years of a like-new, tarnish free appearance for your Maximum instrument. Our simple mounting system makes it easy to remove from the wall for battery replacement or to make adjustments for different locations.
