NOTE:  If making a new TIDE clock, measure the thickness of your dial to make sure you have enough shaft length to go through the case.
If replacing an existing TIDE clock motor, remove non-working motor and compare your dimensions to our specs to select the correct movement.

Our tide clock motors work best for the Atlantic Ocean and its surrounding waterways due to their semidiurnal tides (2 high and 2 low tides per day).
