Below are some questions  you may have concerning a product you purchased from Coastal Tide Clocks.   


a. Make sure you have a new alkaline battery and that the battery is installed correctly (positive/negative ends).  Be sure the metal tabs are making good contact with the battery.

b. Check the hands to make sure they are not touching each other or touching the dial, lens, or glass. First, make sure the base of the hand (where the hole is) is parallel with the dial or the surface, not tilted up or down. This can make the hand be low on one side of the dial and high on the other side.  In most cases, that will solve the problem. If not, then carefully bend the hand(s) so they will clear.  








c. If you are using a cap nut to hold the minute hand on make sure it is on tight and flush on the minute shaft so the minute hand will not rock up and down. If the hands are on correct you may still need to bend the hand up slightly.


    d. In rare cases, the bottom of the second hand where it attaches to the pin shaft could be pushed down too far and rubbing or touching the top of the minute shaft.  In this case, raise the second hand a little so it will not touch the top of the shaft.

 2. MY CLOCK IS RUNNING SLOW:  Keep in mind, old, weak, or defective batteries can make the movement run slow or stop. 

3. MY CLOCK IS RUNNING FAST:  Movements may gain or lose a few minutes a year - this is not a defect. 


a. The hour hand shaft on the movement is tapered (small at the top and bigger at the bottom).  The more you push the hour hand down on the shaft, the tighter on the shaft the hand should get.  Gently push the hand down on the shaft.  If your hand has a brass bushing, it may be slipping (if your hour hand has a bushing). 

b. Gears could be stripped in the movement.  To check this, make a mark on the shaft with a marker and turn the wheel on the back of the movement.  Check to see if the mark moves.  If so, it is probably NOT a stripped gear.


a. There only two types of minutehands that Coastal Tide Clocks sells are:

    1) ROUND holes  that PUSH ON like the hour hand.  NOTE:  Not all push-on style hands are compatible with all motor shafts.

    2) OBLONG (not round) holes that use a nut.  This minute hand has to be lined up with the oblong shaft of the movement before it will drop on the shaft to allow the open or cap nut to be installed.  Our minute hands with oblong holes are called "I" shafts and use a nut.  They are NOT push on. 



The cap nut or open nut is not tight, cross-threaded, or stripped.  Look at the cap nut to see if it is on the minute hand shaft straight.  If not, remove the cap nut and replace it correctly on the shaft.  It should go on smoothly and be square to the shaft, not angled up or down.  Hold the minute hand in place with one hand and tighten the nut with your other hand until it makes good flat contact and is reasonably tight to keep the minute hand from flopping.  DO NOT OVER-TIGHTEN as you can strip the brass nut or shaft.  

7. SHAFT CAP NUT, OPEN NUT, PIN CAP OR SECOND HAND WILL NOT FIT MY MOTOR:  Not all cap nuts, open nuts, or pin caps are interchangeable.  Example: a quartex movement shaft may be different than a quartz movement shaft, and the pins in the shaft may also be a different size, making it so a pin cap or second hand will not fit each other.

8.  REPLACEMENT OF SECOND HAND PIN  Sometimes when removing the second hand or cap from any quartz-type clock movement the pin may come out of the movement. The pin can be easily re-installed by feeling for the hole in center of the SECOND HAND WHEEL inside the movement.  Then push the pin in flush to the minute hand shaft. If it does not go in flush, it is not in correctly.  When re-installed correctly, you will be able to see the second hand or cap turning. 

9.  INFORMATION ABOUT THE 724 - 7-DAY AND/OR 24-HOUR MOVEMENT :  This motor has a switch on the  back and two wires out the top  In the 7 day mode the switch is to the left and 24-hour switch is to the right. To change or put it in the mode you want, you must FIRST remove the battery and move the switch back and forth a few times to the correct mode, this will reset the mode. Then place the battery back in the motor or connect the red wire to the positive and the black to negative to the remote battery. These wires maybe cut if not used just make sure the bare wires do not touch or the motor will not work.   NOTE:  If using the 7-day mode, you will not be able to see the hand move as it takes one week for the hand to move around the dial ONE TIME. In the 24-hour mode, you will see the hand move around the dial in 24 hours.  If you feel the motor is defective,  1) Try a new battery, making sure the battery is installed correctly.  2) Hold the motor to your ear.  In the 7-day mode you will hear a tick once every 7 seconds.  In the 24-hour mode you will hear a tick once every 2 seconds. This will tell you if the motor is working and if in correct mode. If you do not hear the tick, the hand could be touching something to prevent the motor from running.  To check for this issue, take the motor out of the clock and recheck steps 1 and 2 above. You can also lay the motor on the table and reinstall hand, keeping in mind the hand moves slowly.


10. HOW TO TEST A TIDE CLOCK MOVEMENT: The tide movements used and sold by Coastal Tide Clocks are semi diurnal and will rotate every 12 hours and 25 minutes, or one full rotation, from High tide to High tide indicator (at the 12:00 position on the tide dial). To test your tide clock do the following: set your clock at high tide and a time clock at any hour of the day.  (For example,1)  set your tide clock at high tide 2) set your time clock at 9:00 a.m. 3) come back 12 hours 25 minutes later at 9:25 p.m.)  Your tide clock should be once again on the high tide mark after having rotated one time. Keep in mind, no mechanical quartz tide movements will precisely correspond with tide chart tables.
