Hermle Bergamo Mantel Clock

1. Introduction

Thank you for choosing the Hermle Bergamo Mantel Clock. This exquisite timepiece combines traditional craftsmanship with a modern aesthetic, featuring a mechanical winding movement and a distinguished Westminster chime. This manual provides essential information for the proper setup, operation, and maintenance of your clock to ensure its longevity and accurate performance.

The Hermle Bergamo is crafted from cherry wood with transparent glass panels, offering a clear view of its intricate brass mechanism. It features an 8-day mechanical winding movement, a 4/4 Westminster striking mechanism on four polished bells, a seconds display, an 11-stone Swiss escapement, and an automatic night shut-off function for the chime.

2. Safety Information

• Handle the clock with care. Avoid dropping or subjecting it to sudden impacts.
• Place the clock on a stable, level surface to ensure proper operation of the movement and chime.
• Keep the clock away from direct sunlight, extreme temperatures, and high humidity, which can affect the wood finish and mechanical components.
• Do not attempt to disassemble the clock movement. Internal repairs should only be performed by a qualified clockmaker.
• When winding, turn the key gently and avoid over-winding, which can damage the springs.

4. Setup

4.1 Unpacking and Placement

1. Carefully remove the clock from its packaging. Retain all packaging materials for future transport or service.
2. Place the clock on a sturdy, level surface, such as a mantelpiece, shelf, or table. Ensure the surface can support the clock's weight and that the clock is not prone to tipping.
3. Avoid locations with excessive vibrations, direct sunlight, or significant temperature fluctuations.

4.2 Winding the Movement

The Hermle Bergamo clock features an 8-day mechanical movement and requires manual winding. There are typically three winding arbors (holes) on the clock face or back:

• Left Arbor: For the chime mechanism.
• Center Arbor: For the timekeeping mechanism.
• Right Arbor: For the strike mechanism (counting the hours).

To wind the clock:

1. Insert the winding key firmly into each arbor.
2. Turn the key clockwise until you feel firm resistance. Do not force the key past this point, as over-winding can damage the springs.
3. Wind all three arbors completely once a week, preferably on the same day and time, to maintain consistent operation.

4.3 Setting the Time

1. To set the time, gently move the minute hand (the longer hand) clockwise.
2. Pause at each quarter hour to allow the chime mechanism to complete its sequence. This synchronizes the chime with the time.
3. Do not move the minute hand counter-clockwise, as this can damage the movement.
4. The small sub-dial indicates seconds and will move automatically once the clock is running.

4.4 Chime Synchronization and Night Shut-off

The Westminster chime plays a melody at the quarter, half, three-quarter, and full hours, followed by the hour strike. The clock features an automatic night shut-off function, which silences the chime during specific nighttime hours (typically between 10:00 PM and 7:00 AM, though this can vary slightly by mechanism). This function is factory-set and does not require manual adjustment.

If the chime and hour strike are out of synchronization after setting the time, allow the clock to run for a few hours. The mechanism is designed to self-correct over time. If persistent issues occur, consult the troubleshooting section.

5. Operating Instructions

5.1 Regular Winding

For optimal performance, wind your Hermle Bergamo clock fully once a week. Choose a specific day and time each week to establish a routine. Consistent winding ensures the springs maintain adequate tension for accurate timekeeping and chime operation.

5.2 Time Adjustment

Minor time adjustments can be made by carefully moving the minute hand clockwise. If the clock is running consistently fast or slow, it may require regulation. This is an internal adjustment best performed by a professional clockmaker.

5.3 Chime Operation

The Westminster chime will automatically play its melody and strike the hours. The automatic night shut-off feature will silence the chime during the designated nighttime period, resuming in the morning. There is no manual override for the night shut-off on this model.

6. Maintenance

6.1 Cleaning the Case and Glass

• Dust the cherry wood case regularly with a soft, dry cloth. For a deeper clean, use a wood-specific cleaner sparingly, applied to the cloth first, not directly to the wood.
• Clean the glass panels with a soft, lint-free cloth and a non-abrasive glass cleaner. Spray cleaner onto the cloth, not directly onto the glass, to prevent liquid from seeping into the movement.
• Avoid using abrasive cleaners or harsh chemicals, which can damage the finish.

6.2 Movement Care and Oiling

The mechanical movement of your Hermle clock requires periodic professional servicing and oiling, typically every 5-7 years, depending on environmental conditions. This ensures the intricate gears and pivots remain lubricated and free from wear. Do not attempt to oil the movement yourself, as improper lubrication can cause damage.

6.3 Handling and Moving

When moving the clock, always lift it from the base. Avoid carrying it by the top or sides, especially if the glass panels are not securely fixed. For long-distance transport, it is recommended to secure the chime hammers and pendulum (if applicable, though this model is a mantel clock) and re-package the clock in its original protective materials.
