A Simple Guide to Setting up A Vienna Regulator Weighted Clock

  1. Hang the case on the wall making sure that the fixing screw/nail is 100% secure with no chance of it pulling out the wall. The wall must be plumb or you will have problems with the running of the clock.
  2. Using a small spirit level, make sure that the case is also level, use the side of the case to level it up first, then across the bottom.
  3. Take the pendulum and hang it onto the suspension spring at the top of the inside of the case. The suspension has a pin, the pendulum has a hook which is slid up through the spring and dropped into place, it should hand nice and easy, and not be touching the gong.
  4. Take out the dial and movement and turn it around. You will see a metal rod with a small “hammer” at the end, this is for the chiming. When you slide the movement into place, you must lift the hammer up and out of the way. This is to allow the leader to slide into the slot on the pendulum. If you do not lift the hammer out of the way, it will hit the pendulum and the movement will not slide all the way into place.
  5. Check that the weight lines are on the large spools and haven’t dropped down the front and are trapped, this will also mean the clock will not run.
  6. Slide the movement into place by means of the mounting piece on the backboard of the case. Remember to lift the hammer out of the way. After the leader (which is a metal pin hanging from the back of the movement) has been slotted through the slot in the pendulum, the hammer can be lowered into place behind the pendulum. Make sure now that the pendulum is hanging completely free, if it is rubbing on the back of the movement, or the wire chiming gong, the clock will not run. The hammer should now be resting just slightly above the gong.
  7. When you are satisfied that the pendulum is completely free, go down to where the weights are hung. The pulleys will be upside down, hanging on the weight lines. Turn them the right way up, and run the lines around the pulley so that the hook where the weights are hung are at the bottom. Now simply hang the weight on. Repeat for the other side if the clock is a two weight.
  8. Now gently swing the pendulum, if the clock is level, you should hear an even ticking, similar to someone walking, tick, tock, tick, tock. If the beat is uneven, ie. tick, tock ... tick, tock ... tick, tock - you must adjust the pendulum leader. Next to the pin which goes through the pendulum, there are two nuts, one either side. Take one and turn it clockwise, just a little. If the ticking is now more even than before, turn a little more until you are satisfied that the ticking is absolutely even, very important. If after turning the nut, the ticking is LESS even, then simply turn it the other way, and repeat until you have it even. Set the time by moving the minute hand, let the clock chime fully on each hour and half hour when doing this.
  9. To regulate the time, there is a nut at the bottom of the pendulum. If the clock is running slightly fast, turn the nut to the left to enable the pendulum bob to lower, this will make the clock run slower, just a little at a time. If the clock is running a little slow, turn the nut to the right to lift the pendulum bob, this will make the clock run a little faster. Adjust once a day until the clock is accurate. Vienna regulators are precision clocks, if they do not run, it is normally due to something rubbing, (ie the pendulum), or the clock is not perfectly “in beat”.
  10. Enjoy your clock.
