Tide & Time Clock

Please note these clocks take 3-5 working days to make and test
 
The clock measures approx 25 cm x 25 cm
 
Tide clocks or "indicators" show how much time before high or low tide. 
The lunar day, or time it takes the moon to reappear at the same place in the sky, is 24 hours and 50 minutes.  Most locations have two tides each day. Because of this, your clock rotates every 12 hours and 25 minutes or twice daily.
 
Set the time hands first using the adjusting wheel as the tide time will adjust with the time hands. This is normal. Then set the tide hand afterwards to the tide at your location using the bigger bottom adjusting wheel.
 
Please note the mechanism for this clock is deeper than a standard clock mechanism. As a result the clock will sit about 25mm away from the wall.
 
Clock is fitted with a gold metal hands for the time and a blue metal hand for the tide.
 
Slate thickness will vary as its a natural product but typically will measure between 3 mm - 5 mm thick. 
 
Clocks are etched onto reclaimed slate tiles or tile acquired from local roofers after job their is finished when possible. This means that some clocks may have 2 small approx 3mm holes used for fixing tiles to roofs.
Slate colours may vary from grey/green to dark grey depending on slates acquired at time.
 
As this product is Laser surface etched the colour of etching can vary from white to light grey depending on slate properties.
