Antique clocks are more than just functional timekeepers; they are intricate pieces of history that combine mechanical engineering with fine artistry. To be officially considered an antique, a clock must generally be at least 100 years old. Whether you have inherited a family heirloom or are looking to start a collection, understanding the basics of identification, valuation, and maintenance is essential.
Common Types of Antique Clocks
Antique clocks come in various shapes and sizes, often designed to fit specific areas of a home. Identifying the style of your clock is the first step in determining its history and value.
Longcase (Grandfather) Clocks
Longcase clocks, commonly known as grandfather clocks, are tall, floor-standing timepieces driven by weights. They typically stand between six and eight feet tall and feature a pendulum housed within the wooden case.
There are also smaller versions known as grandmother and granddaughter clocks. Grandmother clocks are usually between five and six feet tall, while granddaughter clocks are typically under five feet.
Mantel and Shelf Clocks
Mantel clocks are designed to sit on a fireplace mantel or a sturdy shelf. They are usually spring-driven rather than weight-driven, which allows them to be much more compact than longcase clocks.
These clocks were very popular in the 19th century and come in various styles, including French ormolu, wooden beehive shapes, and black mantel clocks made of slate or marble.
Wall Clocks
Wall clocks are mounted directly to the wall and can vary significantly in design. Common styles include the “Banjo” clock, which has a distinct neck and circular base, and the “Regulator” clock, known for its high accuracy.
Cuckoo clocks are also a popular type of wall clock. Originating in the Black Forest region of Germany, these feature a wooden bird that emerges to announce the hour.
How to Identify an Antique Clock
Identifying the maker and age of a clock requires a close inspection of several key features. Start by looking for a signature or a trademark on the clock face or the internal movement.
Check the Dial and Backplate
Many clockmakers engraved their names or company logos on the dial (the face) or the backplate of the internal movement. You may need to open the back of the case to see the movement markings.
If you find a name, you can research it in horological databases to find the years the maker was active. This provides a reliable window for the clock’s production date.
Examine the Materials
The materials used in the clock’s construction can offer clues about its age. Early clocks often used hand-forged iron or brass parts, while later 19th-century models used mass-produced components.
The wood used for the case also tells a story. Mahogany and walnut were common in high-end English and American clocks, while oak and pine were often used for more modest pieces.
Look at the Glass and Screws
Antique glass often has slight imperfections, such as small bubbles or a wavy texture, which indicates it was hand-blown. Modern replacement glass will look perfectly smooth and flat.
Similarly, handmade screws from before the mid-19th century will have irregular threads and off-center slots. Uniform, perfectly machined screws usually suggest a later date or more recent repairs.
Determining the Value of an Antique Clock
The value of an antique clock depends on several factors, including its rarity, condition, and whether it is in its original state. A clock that has been heavily modified may be worth less than one with all its original parts.
- Authenticity: Clocks with original movements, dials, and cases are the most valuable to collectors.
- Condition: A clock that is in good working order and has a well-preserved case will command a higher price.
- Provenance: If a clock has a documented history or belonged to a notable person, its value can increase significantly.
- Complexity: Clocks with “complications,” such as moon phases, calendars, or complex chiming melodies, are generally more sought after.
Essential Care and Maintenance
Proper care is vital to ensuring an antique clock continues to function correctly. Because these are delicate mechanical instruments, they require a gentle touch and regular attention.
Winding Your Clock
Most antique clocks need to be wound every 30 hours or every eight days. It is a common myth that you can “overwind” a clock; the resistance you feel when the spring is tight simply means it is fully wound.
Always use the correct size winding key to avoid stripping the winding arbor. If you feel excessive resistance or hear a grinding sound, stop immediately and consult a professional.
Setting the Time
When setting the time, it is usually safest to move only the minute hand in a clockwise direction. If the clock strikes the hour, allow it to finish chiming before moving the hand to the next position.
Never move the hands counter-clockwise on a clock that strikes or chimes, as this can damage the internal synchronization mechanism. Some modern antiques allow this, but it is best to avoid it as a general rule.
Placement and Environment
The environment where you keep your clock affects its longevity. Avoid placing antique clocks in direct sunlight, as this can fade the wood finish and dry out the internal oils.
Keep clocks away from heat sources like radiators or fireplaces. Fluctuations in temperature and humidity can cause the wooden case to expand and contract, potentially leading to cracks.
Professional Servicing
Just like a car, a mechanical clock needs regular oiling and cleaning. Every five to ten years, you should have a professional horologist (a clock specialist) inspect the movement.
They will remove old, gummy oil and apply fresh lubricant to the pivot points. This prevents friction from wearing down the delicate brass and steel parts of the movement.
Common Problems and Quick Fixes
If your clock stops running, it may not necessarily need an expensive repair. There are a few common issues that you can check yourself before calling a professional.
The Clock is Not Level
For a pendulum clock to run, it must be perfectly level. If the clock is tilted even slightly, the “beat” (the tick-tock sound) will be uneven, causing the clock to eventually stop.
Listen to the rhythm of the tick. It should be steady and even, like a metronome. If it sounds irregular, use small shims to level the clock until the beat is symmetrical.
The Hands are Touching
Sometimes the hour and minute hands can become slightly bent and catch on each other or the glass. This creates enough friction to stop the movement.
With the clock stopped, gently check to see if there is clearance between the hands. If they are touching, very carefully bend one hand slightly away from the other to clear the path.
Buying and Selling Antique Clocks
If you are looking to buy or sell, it is important to do so through reputable channels. This ensures that you are getting a fair price and an authentic item.
Specialized antique auctions and established dealers are the best places to find high-quality pieces. When buying online, always ask for photos of the movement and a video of the clock running and chiming.
If you are selling, consider getting a professional appraisal. Knowing the specific model and current market demand will help you set a realistic price and attract serious collectors.
Antique clocks are fascinating links to the past that add character and a sense of history to any room. By identifying your clock correctly and following a regular maintenance schedule, you can ensure that your timepiece remains a functional and beautiful part of your home for many years to come.
