QUARTZ TIME and TIDE CLOCK
The action of the tide is very complex and involves many factors, which must be considered to describe the tide exactly at any given place. A computer usually does the calculations necessary for compiling the official Tide Tables. The Tidal Clock does not claim to give you the exact time of the tides at a given place, but it will give you the average state of the tide, which satisfies most peoples needs.
To set your Tidal Clock
1. At the back of the movement, you will find the knob for setting the regular clock hands (Small round plastic wheel positioned on the right) and the knob for setting the tide indicator hand (positioned right at the bottom of the clock movement, large wheel].
2.The tide indicator hand should be set to high tide when the next high tide in your area occurs. As a general rule, it is best to set the tide hand at high tide during a full or new moon. If this is not possible, we suggest you check the reading of the tide hand at the next full or new moon. If, at that time, the tide hand is not indicating to high tide, adjust it with the wheel. Further adjustment may be necessary from time to time.
For Fast easy set up
Time regulation - Your clock is set at the factory for a deviation of about 1-minute per year at a room temperature of 20 centigrade. Please note that high temperature changes may also effect the accuracy.
Your clock should run for about 1 year on the same battery. If the clock stops or starts to lose time - always check the battery. The battery must be changed within 2 years to avoid potential corrosion damage.
Your Tidal Clock movement has four hands - the tidal hand running 50 minutes late every 24 hours, thus indicating the average times of the tides at a given point, the regular hour, minute and second hand, giving you the regular time of the day.
