White Wood Oyster Tide Clock

Product Features

• This handcrafted tide clock from France provides an effortless way to check the tides.
• With a natural beech frame, matching hand, and mineral glass face, it accurately indicates whether the tide is incoming or outgoing, as well as the time remaining until high or low tide. 
• Diameter is 12-in and depth is 1-5/8-in deep.
• Uses 1 AA battery (not included)
• To set, find a source for high and low tides for the location you want to track (easily found on the web or newspaper.)  Determine the exact time of high tide, use the dial in back of the clock to set it in the 12 o'clock position (high tide), and insert the battery.  The clock will then automatically track the tides from that point on.
• Please note that this product may not be accurate for locations in California or the Gulf of Mexico, as their tides are diurnal or mixed.
