Outstanding Quality Antique Victorian Figured Mahogany Grandfather Clock with Painted Arched Dial and Moon Roller, 1850
Priced at £4,250 from London City Antiques
Introduced in the late seventeenth century following the invention of the anchor escapement.
Early antique grandfather clocks needed long cases to hide heavy weights and a long pendulum.
Notice how the dials changed from square brass plates to painted arched iron faces by the Georgian era.
Provincial makers bought standard movements from industrial hubs like Birmingham and fitted them to locally made cases.
Thomas Tompion built sophisticated longcase clocks in London during the late seventeenth and early eighteenth centuries.
George Graham, working alongside Tompion, pioneered the deadbeat escapement for greater timekeeping accuracy.
Research regional clockmakers like the Whitehurst family in Derby if you spot painted dials from the Midlands.

Early cases rely on pegged mortise and tenon joints in solid timber, reflecting basic seventeenth-century joinery traditions before specialized cabinetmaking evolved.
Tap the side panels to feel how later Georgian examples use thin cabinet-made framing to support expensive veneers.
Hand-cut steel pinions and brass wheels filed by individual craftsmen.
"Thirty-hour versions function on a single weight driving both the time and strike trains through an endless rope system."
"Moon phase dials above the main face helped rural owners plan night travel by moonlight."
"Count the clicks when winding, as original ratchets have a distinct, heavy mechanical sound."
Based on almost 25 years of Sellingantiques UK antique market data, Antique Grandfather Clocks appeared 2201 times (out of 1,100,000 antiques) which gives it a rarity score of 64/100.

Remove the pendulum and weights before moving the case. Transporting a clock with these heavy parts attached will rip the movement apart from the inside. Secure the suspension spring so it cannot bend.
Lay the case flat on its back if you cannot move it upright. Pack the hood separately in a padded box to protect the glass.
The case is probably not sitting level on the floor. An unlevel case throws the escapement out of beat, meaning the tick and tock are uneven. This causes the pendulum to lose momentum and stop.
Pack thin slips of wood under the base until the ticking sounds exactly even. If the floor is carpeted, the heavy case might settle unevenly over time and require adjustments.
Dust it gently with a soft dry brush. Do not apply liquid metal polish to an antique dial.
Polish gets trapped in the engraved numerals and reacts with the old silvering. It ruins the contrast and leaves a white crust that is difficult to remove.
Most eight-day striking movements have a simple warning system that can fall out of sequence. If you let the clock run down fully, the strike train might stop while the going train keeps ticking.
Wait until the clock strikes, count the chimes, and then carefully move the hour hand to match that number. The hour hand is usually held only by friction. Never force the minute hand backwards past twelve.
