How to Find Out Who Made Your Clock

That mysterious antique clock on your wall or mantle might be worth more than just sentimental value—but only if you know where it came from. Whether you found it at an estate sale, inherited it from a family member, or picked it up at a flea market, discovering who made your clock is the first step to unlocking its full story.

Clockmakers left many subtle clues hidden inside the movement, printed on the dial, or stamped into the case. This guide will walk you through exactly how to investigate your clock’s origin and narrow down its manufacturer using clear, proven methods.

Why Clockmaker Identification Matters

Every clock has a history. Identifying the maker gives you insight into its age, value, and mechanical design. It also helps you decide whether restoration is worthwhile, what parts it might need, and how to properly care for it.

More importantly, knowing the clockmaker can dramatically affect value. For instance, a German-made Hermle or Gustav Becker movement carries more resale potential than a mass-produced modern replica. Similarly, a Seth Thomas or Ansonia movement made in the U.S. often commands collector interest due to historical significance.

Start by Inspecting the Clock Movement

The first and most reliable place to check is the movement—the mechanical system that powers the clock. To access it, gently open the back of the case or remove the faceplate (only if you’re comfortable doing so). Use a flashlight and magnifier to check for the following:

• Stamped Names or Initials – Look on the back plate, front plate, or movement base.
• Serial Numbers – Many manufacturers used number sequences to identify batch and year.
• Logos or Symbols – Some brands used icons instead of names, such as an anchor, a bell, or a gear.
• Country of Origin – “Made in Germany,” “France,” or “USA” can help narrow it down quickly.

If you see a mark like “No (0) Jewels Unadjusted” or “E. Ingraham Co.” engraved into the brass, you’re on the right track.

Don’t Rely on the Dial Alone

Many dials feature names printed or painted across the front—but don’t take this as definitive. Retailers often branded the clocks they sold, even if the internal movement came from a different company.

For example, department stores in the 19th and 20th centuries would buy clocks in bulk and request custom dials featuring their own store names. That means your clock may say “Marshall Field & Co.” on the face, while the movement inside was made by Sessions or New Haven.

When there’s a mismatch, trust the movement over the dial. The internal parts usually reveal the actual manufacturer.

Check for Labels, Stamps, and Stickers

Look for any printed or stamped information on the clock’s case. These may appear:

• On the backboard
• Under the base
• Inside the case behind the pendulum
• Glued to a panel or shelf

These labels may list the maker, city of origin, model number, and even instructions for operation. Some are decorative, while others are plain black-and-white manufacturer labels. Even if a label is partially missing or faded, you can often compare fonts or slogans with known examples to verify the source.

Keep in mind: paper labels were most common in American clocks from the 1800s and early 1900s. British and European clocks were more likely to use stamps or engraved plates.

Use Online Clockmaker Databases and Reference Books

Once you’ve located markings, match them to a reliable source. There are excellent books and online databases that catalog trademarks, logos, and movement layouts used by known clockmakers. A few examples:

• Clock and Watch Trademark Index by Karl Kochmann
• Trademark and logo image galleries by clock enthusiast communities
• Historical archives maintained by museums and restoration groups

Compare your markings to known logos or search by movement features such as gear layout or chime function.

If your clock has a logo that resembles a crown, an eagle, or an anchor—it’s likely European. Cross-reference the symbol with maker charts to narrow it down.

Identify the Style and Time Period

Clocks often reflect the design trends of their time. While not definitive, recognizing the style can help you narrow down the era and country of origin. Consider these common pairings:

Use these clues alongside your movement inspection to cross-reference possibilities.

Common Makers and What to Look For

Here are just a few well-known makers and the clues they often leave behind:

• Seth Thomas – Stamped “S.T.” or full name, often on 8-day mantel/wall clocks.
• Ansonia Clock Co. – Marked with “A.C.Co.” or full name on movements and labels.
• Gustav Becker (Germany) – Often includes a crossed anchor and GB logo.
• Hermle – Modern movements marked “Hermle” and date-coded.
• Junghans (Germany) – Recognizable star logo with a “J” inside.

There are hundreds of others, especially among European and English makers. If you find a unique marking, it may point to a regional or short-lived manufacturer—which often makes your clock even more collectible.

When to Ask an Expert

If you’re unable to identify the maker or need help restoring the clock, reach out to an experienced clock repair specialist. They can examine gear structure, materials, movement construction, and case style to help confirm the origin.

Photos also help. Be sure to photograph:

• The movement from multiple angles
• The dial and hands
• The case front and back
• Any labels or markings

With that, an expert can usually point you in the right direction—or even provide an appraisal.

Final Thoughts

Finding out who made your clock is part mystery and part craftsmanship appreciation. Once you learn how to inspect the movement, cross-check symbols, and interpret the design, you’ll uncover far more than just the name of a company—you’ll understand the clock’s legacy.
