A Rare Thomas Weeks Twin Fusee Striking Balloon Clock with Exceptional Provenance.

18th century
Description

An extremely rare bracket clock by Thomas Weeks. The movement has circular plates with four pillars and twin chain fusees and spring barrels, strikes the hours on a bell and has Weeks’ signature exposed deadbeat escapement visible in front of the back plate. The back plate is engraved with delicate foliate scroll work in the rococo manner, as is the wedge-shaped pendulum. The movement is housed in a polished brass drum with convex glass doors to the front and back of the clock the bezels with millegrain detail to the edges, surmounted by a brass urn finial also with millegrain detail. The white enamel roman dial signed Weeks, Coventry Street London with pierced brass hands and a blued steel centre seconds hand.

The unusual pendulum is of particular note shaped to swing in the very narrow space afforded by wasted satinwood case, complete with hold fast, the pendulum can be secured in the case by the circular brass hatch on the back of the clock.

All other examples of this style of clock by Weeks that we know of are single fusee timepieces. The deadbeat escapement allows for the addition of the centre seconds complication, something Weeks may have developed from the work of James Cox for the Chinese market.

This clock was almost certainly commissioned by William Courtenay, 9th Earl of Devon during an extensive refurbishment of Powderham Castle, in preparation for his 21st Birthday in 1789. We recently acquired it from William Courtney’s descendants and it has been at Powderham Castle since it was made in the 18th century.

The celebrated Haymarket emporium established by the clockmaker & jeweller Thomas Weeks (1743-1834) was titled 'The Royal Mechanical Museum' from 1788. Weeks followed the fashion established by James Cox (d. 1788) and Henri Maillardet of the Swiss/French company of Jaquet Droz for exhibiting highly ornamental automaton clocks as part of London's great trade attractions.

Derek Roberts (Mystery, Novelty and Fantasy Clocks, Atglen, 1999, p.169) notes that when James Cox disposed of his museum by lottery in 1775 a number of pieces, including an automaton silver swan, now at the Bowes Museum, Barnard Castle, were purchased by Thomas Weeks who subsequently exhibited them in his own museum. According to 'The Picture of London 1802', 'The grand room, which is 107 feet long, and 30 feet high, is covered entirely with blue satin, and contains a variety of figures, which exhibit the effects of mechanism in an astonishing manner.'

The Weeks museum was in effect a very exclusive showroom, the public were required to subscribe to the museum at exorbitant cost; prior subscription would admit four people at the cost of 1 Guinea or if no prior subscription had been purchased it would cost one guinea on the door (roughly equivalent to £200 in today’s money) The tickets were directed specifically at the upper end of 18th century London society and were printed with the following;

“T.Weeks most humbly felicits the Nobility & Gentry, as early as possible to view his Specimen, which is Two Temples, near seven feet high, supported by Sixteen Elephants, embellished with Seventeen Hundred pieces of jewellery, in the first stile (sic) of exquisite Workmanship, abounding in Scenes at once picturesque and pleasing. These two pieces, engaged for the Emperor of China at Nine Thousand Pounds, may be seen every day from Twelve to Four and from Six to Nine at 2s 6d each.”

Weeks’ museum was a famous attraction in central London and operated as showroom for his and the Late James Cox’s work. Visitors could buy small luxury items like ink stands and telescopic silver toasting forks or commission more elaborate pieces such as secretaire bureaus with barrel organs fitted into the bases or in this case a clock.

William Courtney 9th Earl of Devon, known as Kitty to his friends, was an extravagant entertainer, known for his beauty and his acute artistic sensibility, Courtenay was a notable figure in Regency society.

Antiques are the ultimate green purchase. By choosing historical pieces over newly manufactured goods, you completely eliminate the carbon footprint of modern mass production while preserving exceptional, timeless craftsmanship.

A balloon clock is an English spring-driven timepiece named after its waisted case profile, which resembles an inverted hot air balloon. Emerging in the late eighteenth century during the Georgian period, this form remained fashionable through the Regency era, typically featuring a pedestal base, circular dial, and decorative brass mounts.

These clocks were predominantly crafted using wood veneers such as mahogany, satinwood, or flame veneer over an oak carcass. The mechanical interior usually incorporates a spring-driven twin fusee movement with wire or chain gut, an enamel dial with Roman numerals, and cast brass elements including ball feet and urn finials.

Authentic period examples feature hand-cut gears, heavy cast brass backplates, and a fusee cone mechanism visible within the movement. The dial often bears the makers name and location, while the veneered wooden case displays natural age-related patination, authentic wear around winding holes, and historic joinery techniques.

Position the clock centrally on a fireplace mantelpiece, sideboard, or study desk to serve as a focal point. Its warm timber tones and refined proportions pair effectively with minimalist art, modern architectural moulding, or classic library settings.

Keep the clock away from direct heat sources and sunlight to prevent the timber veneer from drying or cracking. The mechanical movement should be serviced by a qualified horologist every five to seven years, and the wooden case should be dusted with a soft, lint-free cloth and occasionally treated with beeswax.
