Maintaining the timeless elegance of your Montreux Anniversary Clock requires occasional care, including changing the pendulum. This intricate process demands precision and a delicate touch to ensure the clock’s accuracy and longevity. Follow this comprehensive guide to navigate the task seamlessly, restoring the rhythmic swing of your cherished timepiece.
Before embarking on the delicate task, gather the necessary tools: a small screwdriver, a pair of needle-nose pliers, and a new pendulum that is compatible with your clock model. Ensure that you have a well-lit and stable workspace to prevent any unnecessary accidents. With proper preparation and attention to detail, you can confidently embark on this essential maintenance procedure.
Removing the Old Pendulum
The first step in changing the pendulum on a Montreux Anniversary Clock is to safely remove the old one. Follow these detailed instructions to ensure the process is done correctly:
- Safely position the clock: Place the clock on a stable and flat surface, preferably with a soft cloth underneath to prevent scratching.
- Identify the pendulum anchor: Locate the pendulum anchor, which is usually a small metal hook or bracket mounted on the movement’s frame. It is the point where the pendulum is suspended.
- Immobilize the pendulum: Gently grasp the pendulum bob (the weighted end) and carefully pull it upwards until it comes to a stop. Holding it in this position will stabilize the pendulum and prevent it from swinging during the removal process.
- Remove the pendulum suspension pin: Locate the pendulum suspension pin, a small metal pin that holds the pendulum rod to the anchor. Use a pair of pliers or needle nose tweezers to gently grip the pin and carefully pull it straight out. Note the orientation of the pin, as it needs to be inserted in the same way when installing the new pendulum.
- Detach the pendulum rod: With the suspension pin removed, the pendulum rod will now be free to detach from the anchor. Carefully lift it straight up and out of the clock movement.
Locating the Pendulum Assembly
To effortlessly locate the pendulum assembly within your Montreux Anniversary Clock, follow these detailed steps:
- Unveil the Access Panel: Begin by unhooking the pendulum from its mounting point at the bottom of the clock, allowing it to swing freely. Next, cautiously lift the wooden or glass access panel located at the front of the clock.
- Gently Remove the Bezel: Inside the access panel, you’ll encounter a circular bezel encompassing the clock face. Carefully lift or unscrew the bezel, exposing the inner workings of the clock.
- Locate the Pendulum Aperture: Once the bezel is removed, you’ll notice a central aperture or opening within the clock. This aperture serves as the point of suspension for the pendulum assembly.
- Retrieve the Pendulum Assembly: Reach gently through the pendulum aperture and grasp the top of the pendulum suspension rod. With a gentle pull, remove the pendulum assembly, which consists of the pendulum bob, suspension spring, and mounting bracket.
Tip: To protect the delicate suspension spring, stabilize the assembly by holding the wooden pendulum bob or the mounting bracket during retrieval and handling.
Safety Note: Before handling any clock components, ensure the clock is disconnected from any power source or batteries to prevent electrical shocks.
Unscrewing the Pendulum
Installing the New Pendulum
Step 1: Remove the old pendulum
To remove the old pendulum, gently grasp the bob and pull it straight down. Be careful not to damage the clock or the pendulum itself.
Step 2: Install the new pendulum
To install the new pendulum, simply insert the shaft of the pendulum into the hole in the suspension spring. Make sure that the bob is hanging straight down and that the pendulum is not touching any other parts of the clock.
Step 3: Adjust the pendulum length
The length of the pendulum will determine the speed at which the clock runs. To adjust the length of the pendulum, use a small pair of pliers to bend the suspension spring. By bending the spring upwards or downwards, you can shorten or lengthen the pendulum.
Step 4: Test the clock
Once you have adjusted the length of the pendulum, test the clock to make sure that it is running accurately. Start the clock and observe the pendulum. If the pendulum is swinging too quickly, you will need to shorten the pendulum. If the pendulum is swinging too slowly, you will need to lengthen the pendulum. Continue to adjust the length of the pendulum until the clock is running accurately.
| Pendulum Length | Speed of Clock |
|---|---|
| Short pendulum | Faster clock |
| Long pendulum | Slower clock |
Setting the Pendulum Swing
Adjusting the pendulum swing ensures accurate timekeeping for your Montreux Anniversary Clock. Follow these steps:
- Check the Level: Ensure the clock is level using a spirit level.
- Start the Clock: Wind the clock and let it run for a few minutes to stabilize.
- Observe the Swing: Open the front door and observe the pendulum’s swing.
- Adjust the Bob: If the swing is too fast, move the brass bob up slightly. If it’s too slow, move it down.
- Fine-Tune: Make small adjustments to the bob until the pendulum swings about 2 inches (5 cm) from left to right.
- Check the Time: After adjusting, monitor the clock for a few hours to ensure accurate timekeeping.
- Repeat Adjustments (if necessary): If necessary, repeat the fine-tuning process until the clock keeps time accurately.
Troubleshooting Swing Issues
If the pendulum swing is still irregular after adjustment, consider the following:
Issue
Solution
Pendulum hits the clock case
Adjust the bob height or reposition the clock.
Pendulum swings erratically
Check for obstructions or drafts that may be affecting the swing.
Pendulum stops swinging
Verify that the clock is wound and check for any mechanical issues.
Pendulum swings too far
Move the bob up slightly or reduce the amplitude of the initial swing.
Verifying Proper Timekeeping
To ensure accurate timekeeping, verify that the pendulum is swinging freely and without obstruction. Adjust the pendulum’s length by turning the nut at its bottom. For every 1/8 of an inch (3 mm) of adjustment, the clock will gain or lose approximately 30 seconds per day. Adjust the nut until the clock keeps time accurately.
Note:
It is essential to make small adjustments gradually and allow the clock to run for at least 24 hours before making further changes. This allows the movement to stabilize and provides an accurate indication of the timekeeping performance.
Determining the Proper Length:
To determine the proper length for the pendulum, observe its swing. If it swings too far, the length needs to be shortened. If it swings too little, the length needs to be increased.
Swing Time:
The ideal swing time for a pendulum is one second from one extreme to the other and back again. This corresponds to a period of two seconds per complete cycle. Use a stopwatch or timer to measure the swing time and adjust the pendulum’s length accordingly.
As a reference, here is a table showing the approximate pendulum lengths for different beat rates:
Beat Rate (Beats Per Minute)
Pendulum Length (Inches)
60
39.2
72
32.4

Maintaining the Clock’s Accuracy
Pendulum clocks rely on the rhythmic swinging of the pendulum to keep time accurately. Maintaining the pendulum’s proper length and adjustment is crucial for optimal precision.
10. Adjust the Pendulum’s Length
The pendulum’s length directly affects the clock’s rate. To fine-tune the accuracy, follow these steps:
Problem
Solution
Clock is running fast
Shorten the pendulum by raising the nut
Clock is running slow
Lengthen the pendulum by lowering the nut
Adjust the nut in increments of 1-2 turns at a time and observe the clock’s performance over a few hours. Repeat the process until the desired accuracy is achieved.
Remember that temperature changes can affect the pendulum’s length. In colder temperatures, the pendulum will contract and the clock may run fast. In warmer temperatures, it will expand and the clock may run slow.
