What is an 18th-century longcase clock?

An 18th-century longcase clock, also known as a grandfather clock, is a tall, freestanding pendulum timepiece housed in a wooden cabinet, predominantly crafted in Britain during the Georgian era.

What materials were used to build Georgian longcase clocks?

Georgian longcase clocks were typically constructed from native hardwoods like oak, mahogany, or walnut, and featured internal brass movements, cast spandrels, and hand-engraved brass dials.

How do you identify an authentic 18th-century oak longcase clock?

Authentic period examples generally display hand-engraved brass dials, cast brass corner spandrels, hand-cut joinery within the case, natural wax patination, and period-appropriate weight-driven movements.

How do you style a longcase clock in a modern interior?

Positioned in an entrance hallway, stair landing, or formal dining space, a dark carved oak longcase clock provides vertical height, architectural interest, and a period focal point alongside contemporary decor.

How should an antique oak longcase clock be maintained?

The oak casing should be preserved using high-grade beeswax polish away from direct heat sources, while the mechanical movement requires periodic lubrication and servicing by a professional horologist.

Condition / Servicing Note:

Please note that antique clocks are complex and sensitive mechanical objects. While some clocks may be running at the time of listing we cannot guarantee ongoing performance without a full inspection and testing period by our specialist horologist. Where inspection, testing, or servicing is required this process can take between 2–12 weeks depending on the clock, the work needed, and current workload. This careful approach helps ensure the clock is properly assessed rather than rushed.

Clock Warranty

All clocks purchased from London City Antiques are supplied with a 12-month warranty from the date of purchase.

This warranty covers mechanical faults and failures arising from normal use. It does not extend to damage resulting from improper handling, unauthorised tampering, accidental or physical damage, environmental factors (including humidity, temperature fluctuations, or exposure to direct sunlight), or misuse.

Should a clock develop a genuine fault within the warranty period that meets the above conditions, we will, at our discretion and at no cost to you, arrange for the repair or replacement of any defective parts. All remedial work will be carried out by a fully qualified and experienced horologist.

In the unlikely event that a fault cannot be satisfactorily resolved, a full refund will be offered.
