What Is the Hermle 791-081 Clock Movement?

Hermle 791-081

If your grandfather clock has stopped chiming or keeping time and you’ve found “Hermle 791-081” stamped on the back plate of the movement, you’re in the right place. This model is a well-known, high-quality German cable-driven clock movement found in many top-tier grandfather clocks sold over the past several decades. At Clockworks, we regularly help customers identify, replace, and restore this exact model.

In this article, we’ll walk you through what makes the Hermle 791-081 unique, how to properly replace or service it, and what parts you’ll need to complete the job right the first time.

What Is the Hermle 791-081 Clock Movement?

The Hermle 791-081 is a mechanical, cable-driven, triple-chime movement made in Germany. It runs for 8 days on a full wind and powers three separate trains: time, chime, and strike. The movement includes a triple chime selection (Westminster, Whittington, or St. Michael), with quarter-hour chimes and hourly strike.

This model powers some of the most prestigious floor clocks, offering:

• Smooth operation
• Deep, rich chime tones
• Precise timekeeping
• Long-term durability with proper maintenance

If you own a Howard Miller, Ridgeway, or another premium grandfather clock, there’s a good chance the 791-081 powers it.

How Do You Identify a Hermle 791-081 Movement?

To identify this movement, remove the clock’s dial or view the back of the movement inside the case. Look for a stamp on the brass back plate that reads something like:

“Hermle 791-081”

Sometimes followed by a pendulum length (e.g., “114cm”) and a date code (e.g., “94” for 1994).

The “791” refers to the series, and “081” refers to the specific model within that series.

If you’re unsure about the model, take clear photos of the front and back of the movement and measure the pendulum length and hand shaft. Clockworks can confirm the movement for you and help recommend a compatible replacement.

What Makes the 791-081 Different from Other Hermle Movements?

The 791-081 stands out due to several key features:

1. Cable-Driven Operation

Unlike chain-driven movements, the 791-081 uses steel cables wound around drums and pulleys. This setup is smoother and more refined, often found in high-end clock models.

2. Triple Chime Functionality

This movement includes three selectable chime melodies. A switch on the dial or side of the case lets you choose between:

• Westminster (classic Big Ben style)
• Whittington (flourishing and lyrical)
• St. Michael (bright and regal)

3. Durability

The 791-081 is built with hardened pivots, brass plates, and quality gearwork that, with proper care, can run reliably for decades.

What Parts Come with a Hermle 791-081 Replacement Kit?

When you order a replacement movement kit from Clockworks, we include:

• Brand new Hermle 791-081 movement (not refurbished)
• New chains or cables, depending on the drive system
• **Pendulum leader and suspension spring
• **Hand nut and mounting hardware

You can also order the movement pre-oiled and tested if you prefer a ready-to-run solution.

If your original movement is more than 25–30 years old, replacement is often better than repair. New movements are built to exacting standards and come with a warranty.

Can I Install the 791-081 Movement Myself?

Yes—with care and attention to detail. Many DIY clock owners successfully install their replacement movement at home using simple tools. Here’s what you’ll need:

• Screwdrivers
• Pliers
• A level (for accurate pendulum setup)
• Time and patience

Installation steps include:

1. Remove the dial and hands carefully
2. Disconnect the weights and pendulum
3. Unscrew and remove the old movement
4. Install the new movement with the included hardware
5. Attach the pendulum leader and suspension spring
6. **Reinstall hands, chime rods, and weights

Should I Repair or Replace the 791-081?

If your Hermle 791-081 movement has never been serviced, is over 25 years old, or is showing signs of wear (such as poor chime quality, inconsistent ticking, or gear play), we strongly recommend replacing it instead of repairing.

Re-bushing and cleaning an older movement can cost more than a new one—and doesn’t guarantee the same long-term performance. Plus, modern replacements from Clockworks come pre-tested, factory-oiled, and ready to install.
