1663-1670 Pioneers of the Pendulum Clock
2013 SOLD 460 K£ including premium
The invention of the pendulum clock by Christiaan Huygens in 1656 revolutionized the accuracy of the time measurement. Easy to make, the new instrument had all the qualities to become immensely popular.
The craftsmen of London managed very quickly to operate specialized workshops. It is generally accepted that the first of these pioneers was Ahasuerus Fromanteel. Two types are available: the table clock and the longcase clock.
On July 9 at Bonhams in London, a table clock signed by Samuel Knibb in London is estimated £ 200K.
Only five clocks are known by this master, and no anonymous instrument can be attributed to him because of the similarity of his production with that of Fromanteel. The clock for sale was made after his arrival in London in 1663 and before 1670 as no later activity of Samuel Knibb has been identified.
Joseph Knibb, who was a younger cousin of Samuel, was his apprentice before 1663. He will be the most outstanding clockmaker in London at the end of his century and his production is abundant.
George Daniels, who was the best connoisseur of antique clocks, appreciated the work of Joseph Knibb. At the auction of his collection at Sotheby's on November 6, 2012, two table clocks were sold respectively £ 1.27 million and 340K including premium.
In the same sale, a longcase clock made about 1685 also by Joseph Knibb had not been sold, probably due to a rebuild of the case. It is listed again, now with a reasonable estimate of £ 40K, at Sotheby's in London on July 10. Here is the link to the catalog.

1677 The Grandfather Escapement
2012 SOLD 1.27 M£ including premium
The use of oscillating pendulums in instruments for measuring time was invented by Christiaan Huygens in the late 1650s. The English will be the pioneers in the manufacture of these pendulum clocks.
Not only it was one of the most useful of all inventions but also, by raising the skills of the mechanical craftsmen, it was certainly a key to the start of the industrial revolution.
Joseph Knibb, who worked in London since 1670, was one of those masters of the time. Skilled clockmaker, he was a precursor and perhaps one of the inventors of the anchor escapement, a basic accessory designed to ensure the isochrony of the pendulum as a function of the deflection angle.
Back to the beginnings of his career. The horological collection of the watchmaker George Daniels, which will be dispersed on November 6 in London by Sotheby's, includes two clocks made by Joseph Knibb, in ebony, with Roman numerals on the dial.
The most luxurious, dated 1677, has the shape already usual in his time of the table clock, a cube with a handle. It is estimated £ 600K.
The other, made around 1685, is a longcase clock, or in a more familiar wording, a grandfather clock. This type of model is an early easy approach to improve the accuracy thanks to the lengthening of the pendulum. It is estimated £ 200K.
Here is already the link to the announcement of the sale.

1693 A Little Clock for Queen Mary
2019 SOLD for £ 1.93M including premium
Established in London since 1671, Thomas Tompion became the best English manufacturer of clocks and watches by the accuracy of his mechanisms, the choice of the best materials and the employment of the best workers. He belongs to the second generation of pendulum clock manufacturers. Sponsored by Robert Hooke, he certainly benefited from the experience of the pioneering Oxford clockmakers.
Aware of the quality of his production, Tompion numbered his instruments, an exceptional practice in his time for a manufactured product. He mixes in a single serialization list the table clocks and the long case clocks. His clocks have a long autonomy. His grande sonnerie pieces offer a repetition of quarters over a long duration.
From 1692 or 1693 Tompion improves the elegance of his design with his Phase Two which includes the cushion dome, the thistle bud handle, the bellflower keyhole and the operation of the mechanism from the front face.
The master seems more interested in standardization than in miniaturization. Nevertheless Number 215 appears as the first of a small series of Phase Two table clocks with a total height of 28 cm including the raised handle. It was sold for £ 170K including premium by Bonhams on December 13, 2011.
Number 222, made especially for Queen Mary II in 1693 and known as the Q Clock, is the smallest clock ever made by Tompion with an ebony case. It is 20 cm high overall with the handle raised. It offers the quarter repetition and an autonomy of eight days.
Re-assembled in 1949 by a collector with its original movement, the Q Clock was sold for £ 440K including premium by Christie's on June 30, 1993. It will be sold by Bonhams in London on June 19, lot 103. The May 20 press release is announcing for this silver mounted royal clock an estimate in excess of £ 2M. A modern replica is joined to the lot.

1705 Longcase Clock by Tompion
2004 SOLD for £ 520K including premium by Christie's

1708 Astronomical Regulator by Tompion
2003 SOLD for £ 620K including premium by Christie's

1725 Astronomical Regulator by Graham
2002 SOLD for $ 1.77M including premium by Sotheby's
narrated in 2021
King Charles II founded the Royal Observatory in Greenwich in 1675. Its objective was to calculate the longitude through the position of the stars to ensure the control of the seas. The first Royal Astronomer, John Flamsteed, established a catalog of stars of unprecedented precision.
The length of the sidereal day is four minutes less than the length of the solar day. In 1691 Thomas Tompion executed a sidereal clock designed by Flamsteed for Greenwich.
On July 11, 2003, Christie's sold a longcase regulator at lot 156 for £ 620K including premium from a lower estimate of £ 150K. This instrument one-of-a-kind in its time displays both solar and sidereal time on a dial with two concentric rings, with a one month reserve. The combination of the two mechanisms is a technical feat, including a wheel with 586 teeth for sidereal time and a wheel with 244 teeth for solar time.
Numbered 483 by Tompion, this regulator was made in his later career. The terminus ante quem is the end of his association with Edward Banger, around 1708 : a plaque bears these two names.
George Graham, who had worked for Tompion since 1688 and will be his successor, is not identified on these plaques. The escapements fitted to 483 are of anchor type with deadbeat, a mechanism tested in 1676 by Tompion from an invention by Towneley, and which will later be known as Graham escapement.
Made circa 1725, the regulator numbered 634 by George Graham offers the very rare and perhaps unique combination of the functions of the 483 with a perpetual calendar. The sidereal and solar time dials are separate. 634 was sold by Sotheby's on June 19, 2002 for $ 1.77M including premium from a lower estimate of $ 150K, lot 172.

1740 Tall Case Clock by Peter Stretch
2004 SOLD for $ 1.7M including premium by Sotheby's
narrated in 2021
Peter Stretch is the nephew of a Staffordshire clockmaker. He knows the best London manufacturers including Thomas Tompion. Fleeing religious persecution, he joins the Quaker community in Philadelphia in 1703 with his family.
This skilful craftsman produced until his death in 1746 all kinds of timepieces, and even some scientific instruments. His works are not dated, but he follows and influences the changing tastes of the rich bourgeoisie of Philadelphia, of which he is a prominent member.
The grandfather clock on the Tompion model became the most spectacular element in bourgeois homes. Stretch first made them in solid walnut and then in mahogany, with a beautiful dark brown color that responded to the Queen Anne taste reinterpreted in Philadelphia around 1740.
A mahogany clock was sold by Sotheby's on October 29, 2004 for $ 1.7M including premium from a lower estimate of $ 600K, lot 205.
273 cm high and very richly carved, it is typical of the later career of Peter Stretch, notably with a signature sarcophagus shaped top. It has remained close to its original configuration. The decoration takes precedence over watchmaking sophistication. The dial is silvered with a date aperture. Its complications are the phases of the moon and the seconds hand.

1755 The Workshops of Newport
2018 SOLD for $ 610K including premium
In Boston, Newport, Philadelphia or Providence, the wealthy New England paterfamilias are fond of luxury furniture to demonstrate their social importance. Dynasties of craftsmen perform this work in local styles. The tall case clocks with complications are technical feats that add to the prestige of their owners.
In October 2004 Sotheby's sold for $ 1.7M including premium a clock made around 1740 by Peter Stretch in Philadelphia. The catalog does not indicate any complication but insists on the magnificence of its 2.73 m high mahogany case.
At the same time the families of cabinetmakers Townsend and Goddard have their workshops in the Quaker district of Newport. They develop for their high quality furniture the Block and Shell decoration which is certainly also imitated by their local competitors and becomes the signature feature of the furniture from that city.
The clockmaker William Claggett was established near Townsend and Goddard. He died in 1749. James Wady who was his apprentice and son-in-law continued his clock models for a few years and died in 1759. Thomas Claggett, son of William, in turn rented a shop in 1755 to make similar clocks.
Wady's activity as a shop owner appears as brief, perhaps only the time to settle the estate of William Claggett who was deemed a bad payer. Towards the end of his career Wady adds the phases of the moon above the main dial and improves the readability of the sub-dial of seconds and of his signature, allowing now to classify in four chronological groups his nine surviving clocks.
A 2.35 m high clock from the third group with a mahogany block and shell case attributed to one of the Townsends was sold for $ 670K including premium by Christie's in January 2002.
A clock of similar size and design but from the last group was sold for $ 440K including premium by Christie's in New York on January 21, 2000. It is estimated beyond $ 200K in the same auction room on January 19, lot 159. It includes a very rare complication which was favored in Newport, the time of the tides.

1766 A Flat Desk with its Clock of Cartonnier
2015 SOLD for € 2.22M including premium
Philippe-Claude Montigny is a cabinetmaker at the end of the reign of Louis XV. Cousin of René Dubois, he is also an occasional collaborator to Etienne Levasseur who is at that time the skilled successor of Boulle. The large bureau plat in the style of Boulle naturally becomes one of his specialties.
All accessories are designed for writing: drawers and pull in the desk, black leathered top and the very tall serre papier now named cartonnier or filing cabinet which is surmounted by a clock.
The desks stamped by Montigny are rare. One of them is estimated € 2M for sale by Christie's in Paris on November 4, lot 510. It retained its matching cartonnier with its original clock as they were described in the inventory of the estate of a former intendant of Louis XVI in 1795. Two period écritoires are joined to complete the equipment.
The desk is adorned with a leafy garland in antiquisant style 'à la grecque' which was fashionable in the early 1760s. It certainly dates from the very beginning of the accession to the maîtrise by Montigny in 1766. The sets of furniture of this period in which desk, cabinet and clock were never separated are of extreme rarity.

1766 Exuberance of George III Timepieces
2013 SOLD 480 K£ including premium
On 12 December 2012, Bonhams sold for £ 385K including premium a clock that had belonged to the collection of King Farouk. Here is the link to their catalog. It is now for sale at Christie's. I repeat below my previous article after changing the information related to the sale:
The clockmakers of London were once the best in the world. In the mid-eighteenth century, James Cox was one of those who maintained this tradition. The Swiss will soon become their main competitors thanks to the progress started by Jaquet-Droz.
The best clocks made by Cox are works of art, with the heavy figuration so appreciated at that time including volutes, animals and masks. A musical clock is estimated £ 150K, for sale by Christie's in London on July 4. Here is the link to the catalog.
With an overall height of 37 cm, this piece dated 1766 is a three-body composition mounted on four high legs terminating on full elephants. It is in gilt bronze adorned with agate panels on the lower chest.
The main dial, at the top, is still surmounted by a winged dragon in silver perched on an urn. The intermediate level offers two dials, one of the main face for the phases of the moon, and the other on the back. The piece retains its original key.
The Qianlong emperor had a predilection for European clocks, and Cox is one of the leading English watchmakers who have exported to China, probably later in his career.
POST SALE COMMENT
Sold for £ 480K including premium, the clock realized a good gain in less than seven months.

1770-1773 French Rotating Spheres
2015 SOLD for £ 600K including premium
From the early eighteenth century, the best English and French clockmakers develop mechanisms simulating the movements of the planets. These instruments are named orrery clocks in England.
The Enlightenment fosters the scientific precision. In addition to the technical achievement already in combination with multiple complications, very competent astronomers such as Lalande and Cassini adjust the astronomical tables and mathematicians like Camus position their gears and wheels.
At the end of the reign of Louis XIV, Jean Pigeon realizes a moving sphere clock on the principle of Copernicus and publishes his invention in 1714. The astronomical clock by Passemant is presented in 1749 at the Royal Academy of Sciences and is used to set the official time of the kingdom. It is kept at Versailles.
The Prince of Conti had little skill in politics but became the greatest collector of his time. Resolutely dismissing the academies and corporations, he commissioned around 1770 the most complex astronomical clock of his time. The clockmaking is made by Mabille and the spheres by Baffert, certainly before 1773 which is the date of bankruptcy of the latter.
The clock displays all the possible elements for measuring time and a beautiful dial for the position of the moon. Extended to the outer planets, the planetary includes six rotating spheres with the highest scientific accuracy. It also marks ecliptic, solstices, equinoxes and zodiac.
Janvier, who had this piece in hand after the Révolution, noted that it is better than Passemant's clock by the accuracy of its annual rotation because it incorporates the calculations published by Camus in 1749.
The planetary clock of the Prince de Conti is estimated £ 600K for sale by Christie's in London on July 9, lot 9.

ca 1774 Régulateur de Parquet by Berthoud
1999 SOLD for £ 1.93M including premium by Christie's
narrated in 2020
The mastery of the seas requires the precise measurement of longitude. The English effort paid off : John Harrison invented the marine chronometer.
The marquis de Choiseul, raised to duc de Praslin in 1762, swapped in 1766 the Ministry of Foreign Affairs for the Ministry of Marine, just as strategic. To cancel the French backwardness, he commissions the two most skilful watchmakers established in Paris, Pierre Le Roy and the Swiss born Ferdinand Berthoud. It is Praslin who conceives the first official French circumnavigation, whose captain is Bougainville.
In 1764 and 1765, Praslin acquires Fouquet's castle in Vaux and a residence in Paris, built on the banks of the Seine for Fouquet's grandson, which becomes the hôtel de Choiseul-Praslin. The luxury of its decoration, including some furniture by Boulle, is worthy of the minister disgraced by Louis XIV.
The régulateur de parquet (longcase clock) from the hôtel's grand salon is a work by Berthoud, with a case stamped by Lieutaud and gilded bronzes by Caffiéri's son. This is of course the best in Paris for that sort of piece. It includes the calendar, complications related to Sun and Moon, a needle barometer, as well as the équation de Berthoud revealed to the Académie des Sciences in 1752 to differentiate between apparent and mean solar times.
This sumptuous 2.66 m high piece of time and furnishing was sold for £ 1.93M including premium by Christie's on July 8, 1999, lot 207. For the date, the only reference is a spring marked 1774.

In 1764 and 1765, Praslin acquires Fouquet's castle in Vaux and a residence in Paris, built on the banks of the Seine for Fouquet's grandson, which becomes the hôtel de Choiseul-Praslin. The luxury of its decoration, including some furniture by Boulle, is worthy of the minister disgraced by Louis XIV.
The régulateur de parquet (longcase clock) from the hôtel's grand salon is a work by Berthoud, with a case stamped by Lieutaud and gilded bronzes by Caffiéri's son. This is of course the best in Paris for that sort of piece. It includes the calendar, complications related to Sun and Moon, a needle barometer, as well as the équation de Berthoud revealed to the Académie des Sciences in 1752 to differentiate between apparent and mean solar times.
This sumptuous 2.66 m high piece of time and furnishing was sold for £ 1.93M including premium by Christie's on July 8, 1999, lot 207. For the date, the only reference is a spring marked 1774.
