- Tides 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 12.5 hours instead of the normal 12, indicating the state of the tide for a chosen location.
- They have hefty solid cast brass casings, scuttle clamps, bevelled glass fronts and brass hands with black subsidiary indicators on light cream faces.
- Outside diameter 9", face diameter 5.5", depth 2.25".
