Hermle 70989-030341 Westminster Wall Clock Instruction Manual

Introduction

Thank you for choosing the Hermle 70989-030341 Westminster Wall Clock. This precision timepiece features an 8-day mechanical movement, a 4/4 Westminster chime, and is housed in an exclusive solid wood case with front and side glazing. This manual provides essential information for the proper setup, operation, and maintenance of your clock to ensure its longevity and accurate performance.

Please read these instructions carefully before operating your clock.

Safety Information

• Handle the clock with care to avoid damage to the delicate mechanical movement and wooden case.
• Do not attempt to disassemble the clock mechanism. Refer all repairs to qualified clockmakers.
• Keep the clock away from direct sunlight, extreme temperatures, and high humidity.
• Ensure the clock is securely mounted on a stable wall to prevent falling.

Setup

1. Unpacking

Carefully remove the clock from its packaging. Retain all packing materials for future transport or storage. Inspect the clock for any visible damage.

2. Choosing a Location

Select a stable wall location away from direct heat sources, air conditioning vents, and areas prone to vibrations. Ensure the wall can support the clock's weight (approximately 6 kg).

3. Mounting the Clock

Securely mount the clock to the wall using appropriate hardware for your wall type. The clock must hang perfectly level for proper pendulum operation and accurate timekeeping. Use a spirit level to verify.

4. Installing the Pendulum

Gently unhook any shipping restraints for the pendulum. Carefully hang the pendulum onto its hook located behind the dial. Ensure it swings freely without obstruction.

Figure 1: Pendulum detail. Ensure the pendulum hangs freely.

5. Winding the Movement

Your Hermle clock features an 8-day mechanical movement. Locate the winding holes on the dial. Insert the winding key (not specified if included, assume it is) and turn it clockwise until resistance is felt. Do not overwind. Wind the clock fully once a week to maintain consistent power.

6. Setting the Time

To set the time, gently move the minute hand (the longer hand) clockwise until the correct time is displayed. Allow the clock to chime at each quarter hour and hour as you advance the minute hand. Do not move the hour hand directly.

7. Starting the Clock

Once the pendulum is installed and the clock is wound, gently push the pendulum to one side and release it. Listen for an even "tick-tock" sound. If the sound is uneven, the clock may not be perfectly level. Adjust the clock's position slightly until an even beat is achieved.

Operating Instructions

1. Westminster Chime Function

Your clock features a 4/4 Westminster chime. This means:

• Quarter Past the Hour: A portion of the Westminster melody plays.
• Half Past the Hour: A longer portion of the melody plays.
• Quarter To the Hour: An even longer portion of the melody plays.
• On the Hour: The full Westminster melody plays, followed by the clock striking the number of hours.

2. Night Shut-off Feature

The clock is equipped with a night shut-off feature, allowing the chime to be silenced automatically during nighttime hours. Consult the specific lever or switch located near the movement (often accessible through the front or side door) to activate or deactivate this function.

3. Strike Position Adjustment

If the clock strikes an incorrect hour after chiming, you can adjust the strike position. Gently move the hour hand (the shorter hand) to match the number of strikes. Do not force the hour hand; it should move freely.

Maintenance

1. Regular Winding

To ensure continuous and accurate operation, wind your clock fully once a week.

2. Cleaning the Case and Dial

Dust the wooden case with a soft, dry cloth. For the dial and glass, use a soft, lint-free cloth. Avoid using abrasive cleaners or chemical sprays directly on the clock.

3. Professional Servicing

Mechanical clocks require periodic professional servicing, typically every 5-7 years, to clean, lubricate, and adjust the movement. This will help preserve the clock's accuracy and extend its lifespan.

Troubleshooting

• Clock Not Running:
  • Ensure the clock is fully wound.
  • Verify the pendulum is properly installed and swinging freely.
  • Check if the clock is level; an uneven surface can stop the pendulum.
• Clock Running Too Fast or Too Slow:
  • The timekeeping accuracy is regulated by the pendulum. To make the clock run faster, raise the pendulum bob slightly by turning the nut at the bottom of the pendulum clockwise.
  • To make the clock run slower, lower the pendulum bob slightly by turning the nut counter-clockwise.
  • Make small adjustments and observe the clock's accuracy over 24 hours before making further changes.
• Chime Not Working or Incorrect:
  • Ensure the chime mechanism is wound (if it has a separate winding hole, which is common for chime clocks).
  • Check if the night shut-off feature is activated.
  • Verify the strike position is correctly set as described in the "Operating Instructions" section.
  • If the chime is still incorrect, gently advance the minute hand past the hour to allow the chime mechanism to reset.
