The Presentation Tide Clock in spun brass makes a valuable Retirement/Anniversary/Wedding gift  for anyone living near tidal water. The clock will predict the average state of the tide once it has been correctly set for the area to be monitored.

Full instructions will be provided to set and use your clock.  Battery driven which is provided.  Please use good quality alkaline batteries and replace every 12 months to avoid battery leakage.  We recommend Super Alkaline 1.5V GP Battery – we do NOT recommend the use of rechargeable batteries.

The primary controller of the tides is the moon.  The average duration between two transits of the moon around the earth is 24 hours 50 minutes and 30 seconds – this is referred to as the lunar or tidal day.  It means the tidal day – to which the tide indicating hand is geared – is 50 minutes and 30 seconds longer than the solar day of 24 hours. 

The west coasts of Europe and Africa and the east coasts of North and South America follow the semi-diurnal pattern of two high and two low tides each day, more or less equally spaced, so your tidal clock can be used.  However certain others coasts such as the west coasts of North and South America are not semi-diurnal, therefore the tide indicating part of your tidal clock will not function in these areas

 

There is a matching Clock, Barometer and Hygrometer/Thermometer in this range for home use.
