1620 An Outstanding Collection of Early Clocks
2009 SOLD 205 K€ with no applied buyer's premium
PRE SALE DISCUSSION
Clockmaking was invented to provide an audible indication of the time, that the sundial could not enable. The English language followed for these instruments the Latin onomatopoeia clocca, which became Clock. This technique was first developed for the purpose of regulating activities and prayers in religious institutions.
The invention of the wound spiral spring allowed the miniaturization of these instruments. Regulating mechanisms improved the accuracy: the fusee was a conical piece of transmission, and the stackfreed had a pressure effect. These techniques compensated for the gradual loss of force of the spring. The dial and hand were soon rendered necessary to add a continuous reading to the discontinued audible information.
In the sixteenth century the development of complications attested the ingenuity of craftsmen. Many secondary information, especially astronomical, became the necessary complement in the most sophisticated instruments. The study of movements led to the creation of automaton animated clocks at that early time.
On May 24 in Milan, Patrizzi auctions an exceptional collection of these instruments of the Renaissance.
One of these clocks, made in South Germany in 1570, includes many complications including the length of the day.
POST SALE COMMENT
This specialized auction was a great success. All 70 lots were sold (white gloves!) for a total of € 2.6 million in excess of 60% to the estimates.
Here are the results of the three lots that I included in my previews:
A gilt brass complicated astronomical revolving table clock, Southern Germany, circa 1570 (as announced in my article above): 125 K €.
A gilt brass and ebony revolving monstrance table clock, probably Germany, circa 1620: 205 K €.
A French alarm table clock, Gilbert Martinot, Paris, dated 1565: 170 K €.
It is both the hammer price and the price paid by the buyer, as Patrizzi auction house does not charge a commission to the buyer, who for that reason does not pay VAT.

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.

1664 The Very Long Nights of a Lit Pope
2009 SOLD 90 K€ with no applied buyer's premium
PRE SALE DISCUSSION
Many discussions on time instruments deal of progress and complexity of mechanisms, but the craftsmen were also to be attentive to the needs of their customers.
Thus Pope Alexander VII, who was an insomniac, wanted a table clock where he could read the time at night. He required it to be silent in order not to disturb him if he slept.
The business was entrusted to Giuseppe Campani, who put a candle behind a pierced dial, named his invention the Notturno, and made it an object of fashion for the Roman aristocracy. He worked with artist Carlo Maratta, whom style is recognized in the colorful religious scenes which adorn the center of the dial. Doing everything to please his specific customers, Campani used for his pieces the external shape of a Baroque altar or of a church facade.
A Notturno clock will be auctioned by Patrizzi in Milan on 28 and 29 November. With a total height of 1 m on a 68 cm base, it is decorated with an oil on copper showing the Assumption of the Virgin between Saints Dominic and Philip. It is very similar to another copy dated 1664, and is estimated 120 K €
Online bidding is powered by LiveAuctioneers, who share the image and catalog.

1665-1667 The Clockmaker of Oxford
2014 SOLD 287 K£ including premium
PRE SALE DISCUSSION
The invention in 1656 of the pendulum clock by Huygens immediately interested the craftsmen of London. It takes the simple form of a cubic box or of a tall furniture in two bodies named longcase clock that may include a longer pendulum.
In the very beginning, it is difficult to distinguish a particular style distinguishing the production of a specific workshop. Fortunately many of them were signed : Samuel Knibb, or Ahasuerus or Johannes Fromanteel, or Edward East. A table clock signed by Samuel Knibb was sold for £ 460K including premium by Bonhams on July 9, 2013.
Samuel Knibb started his business in Newport Pagnell, where he apprenticed his cousin Joseph Knibb. The movings of Samuel to London and of Joseph to Oxford seem simultaneous, in 1662 or 1663.
On March 11 at Donnington Priory in Berkshire, a grandfather clock 1.90m high signed by Joseph Knibb in Oxford is estimated £ 80K by Dreweatts & Bloomsbury, lot 143 in the catalog shared here on LiveAuctioneers platform. This piece directly influenced by the clocks of London was made between 1665 and 1667.
Joseph Knibb moved in his turn to London in 1670, certainly to succeed Samuel. Joseph then left his Oxford business to his younger brother John. The pieces made by Joseph in London are the masterpieces of old English clocks. Aluxurious table clock from the Daniels collection was sold for £ 1.27 million including premium by Sotheby's on November 6, 2012.

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.
Here are the links to the catalogue for the table clock and for the longcase clock.
POST SALE COMMENT
Clocks made by Joseph Knibb were the stars of the George Daniels collection of ancient clocks.
The table clock discussed above was sold £ 1.27 million, and another less luxurious example reached £ 340K. The grandfather clock has not been sold.
Among other makers, let us mention at £ 300K a table clock made around 1697 by Thomas Tompion.
These results include premium.

1698 A Longcase Clock by Thomas Tompion
2009 SOLD 240 K£ including premium
PRE SALE DISCUSSION
Thomas Tompion is considered the most important English watchmaker. Wikipedia tells us that he manufactured about 650 clocks and 5500 watches. His workshop was in London. He was one of very few watchmakers who were admitted to the Royal Society, and was buried in Westminster Abbey.
All of his clocks were numbered. The serial number 301 comes up for sale at Christie's in London on June 4. It is 2.27 m high with a walnut case and dates from around 1698 (then William and Mary). It has an autonomy of one month.
The estimate is 200 K £. In its catalog, Christie's provides three higher results for pieces of similar models. The most expensive, sold in September 2004 for 520 K £ including expenses, had a royal provenance. A visit to their archives allowed me to view a regulator sold 620 K £ including fees in July 2003.
POST SALE COMMENT
The clock remained at its lower estimate. It was sold 240 K £ including premium. I had seen in the catalog that this serial number 301 was a bit (a very little bit) simplified in its decor compared to usual models.

1740 Tall case clock by Peter Stretch in Philadelphia
2004 SOLD for $ 1.7M including premium by Sotheby's
Link to catalogue.
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.
I invite you to watch the video shared by Christie's.

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.
