Your Tide Clock's unboxing is meant to be fun, easy and, if needed, educational!
The Tide Clock mechanism (seperate to the silent clock hands) runs on batteries. Once these are inserted, the clock can be switched on. It will do one or two full rotations of the tide scenery and then sit at "high tide".
We then recommend that you consult your local tide times via the internet and when your next high water is at a convenient time, turn the clock off and then on again. This will mean the clock is at 'high tide' when your local real tide is also at the same. The clock is now in sync and will move every half an hour to update itself
