Portable Brass Cabin Tide Clock With Tracking [JWDn1dCk]

Our Cabin Porthole Range of Clocks, Barometers and Tide Clocks have hefty solid cast brass casings, scuttle clamps, bevelled glass fronts and brass hands with black subsidiary indicators on light cream faces. The movements are good quality - battery-operated quartz for the clocks and silvered aneroid for the barometers. 

Tide Clocks are influenced by the orbit of the moon around the Earth. To show this, our tide clock has an extra hand, which makes a complete sweep at the lunar rate of approximately 12½ hours instead of the normal 12. (Please note: because the lunar cycle varies with the Earth's, there are times in a month when actual tides are a few minutes ahead or behind the clock.)
