1687 The Universal Philosophy revealed to the World
2016 SOLD for $ 3.7M including premium
Isaac Newton was the most brilliant scientific innovator of all time. Late in his life he laid down the rules that had guided his unprecedented method. One of these rules summarizes in a simple sentence how he created the modern physics : to the same natural effects we must, as far as possible, assign the same causes.
One of his outstanding skills was to develop mathematical methods of high complexity to analyze and support his own physical theories. Even before he was 30, he compared the motion of the planets and the fall of the bodies. Essentially preoccupied with his own understanding of the mechanism of the universe, he published sparingly.
In 1684 in London, the scientists of the Royal Society challenged themselves to find the mathematical formulation of the law of motion of the planets described by Kepler. All failed. Halley visits Newton in Cambridge. He is stunned : Newton knows the solution but has lost his calculation notes. The orbital movement of a celestial body is an ellipse whose position of the other body is one of the foci.
The scientific stake is highly important and Halley manages to persuade Newton to disclose in their entirety his results concerning the law of universal gravitation. Edited and financed by Halley, Newton's Latin book entitled Philosophiæ Naturalis Principia Mathematica is published in 1687 with the imprimatur of the Royal Society.
The book is difficult in the opinion of the author himself and the circulation probably did not exceed 300 copies but it is of such scientific importance that Halley and Newton took care of organizing their sale through booksellers. One of them named Samuel Smith is more specifically entrusted to the supply onto the Continent and receives about 50 copies for that purpose.
On December 14 in New York, Christie's sells a copy in a luxury binding in inlaid morocco, presented in that state by Smith to an unidentified recipient. It is estimated $ 1M, lot 167.
Another association copy with a binding of a comparable luxury is known. It was offered to King James II, patron of the Royal Society. This book was sold for $ 2.5M including premium by Christie's on December 6, 2013 over a lower estimate of $ 400K.

1884 The Oldest Marquise
2011 SOLD 4.6 M$ including premium
The meeting between the aristocrat de Dion and the mechanical engineers Bouton and Trépardoux was successful. The steam had proved effective with the locomotives. By developing a propulsion system of small volume that could be mounted on a tricycle or quadricycle, the team actually invented the automobile.
La Marquise, made in 1884, with two pairs of different-size wheels, is the first successful prototype and is still the oldest car capable of running. Its general shape is already not like a boiler, but that of a real car.
In 1887, La Marquise won the first event considered as a car race between Paris and Versailles, without difficulty because it was the only competitor.
Yet the experiments of Benz, begun in 1885, would soon show that the petrol engine was a better choice than steam.
La Marquise was a sensation at Pebble Beach on August 19, 2007, when it was sold $ 3.5 million including premium by Gooding on an estimate of $ 1.5 M. Before this sale, it was illustrated in the article shared by LeBlogAuto.
Certainly, La Marquise likes auctions. It is for sale on October 7 in Hershey PA by RM Auctions. It is conservatively estimated $ 2M.

1923 Photography on Flexible Film
2018 SOLD for € 2.4M including premium
In 1911 Oskar Barnack was hired by Leitz. Founded in the mid-19th century, the Optische Werke Ernst Leitz company established in Wetzlar specialized in precision mechanics for optical instruments.
In the development phase of the cinema, setting the exposure time was an issue. To test it Barnack has the idea in 1913 to insert a 35 mm flexible film horizontally in a still camera. He builds two prototypes of this Leca that will later be spelled Leica for Leitz Camera. The horizontal position makes it possible to use 8 perforations per frame instead of 4 for the vertical rolling in a movie camera. The 24 x 36 mm was born.
Until then the usual practice for positive photography is the contact printing. Barnack loves hiking but he is sick and must avoid heavy equipment. He considers reusing his miniature 24 x 36 mm format. The positives will be achieved by enlargement. He makes a third prototype between 1918 and 1920.
Barnack convinces his boss Ernst Leitz II to continue this innovative experience. To evaluate the feasibility of a production and to test the market, Leitz authorizes in 1923 a small series of 31 cameras numbered from 100 to 130, the 0-Series (in German: Nullserie) of the Leica. It seems that some of these numbers were not finally used.
The 0-Series Leica has some improvements compared to its three precursors, including to allow loading and unloading the film in daylight. The lens cover is now essential for not fogging the film when arming.
The Leica 107 in B- condition was sold for € 1.32M including premium by WestLicht on May 28, 2011 over a lower estimate of € 350K. I commented this great result by stating that the 0-Series Leica is the absolute dream for any collector of cameras. The serial number 116 also graded B- was sold for € 2.16M including premium on May 12, 2012 by the same auction house over a lower estimate of € 600K.
In B+ condition the Leica 122 is one of the best preserved of the series. Its lens cover, folding viewfinder and paintwork are original. It is estimated € 700K for sale by WestLicht in Vienna on March 10, lot 3 here linked to the LiveAuctioneers bidding platform.

1953 The Release of the Secret of Life
2013 SOLD 6.05 M$ including premium
The day after the announcement of the sale of Francis Crick's Nobel medal by Heritage, discussed yesterday in this column, Christie's issued a press release about an extraordinary document of the same origin, to be sold by them in New York on April 10.
Through a mathematical approach to X-Ray views that had been difficult to analyze, Crick and Watson built the model of the double helix of DNA. Copernicus had used a somehow similar method to raise the heliocentric hypothesis when seeking to simplify an apparently too complex data.
Very excited (as he told it), Crick could not keep the secret. The listener is well chosen: he explains with great foresight the result and its consequences in a seven-page handwritten letter dated 19 March 1953 to his son Michael then twelve years old, a college student out of home for his school time.
This first digest work of one of the greatest discoveries is signed Daddy. We see with great pleasure that this research was an actual team work honoring equally the two scientists, "Jim" Watson and Daddy. The schematic diagram of the double helix has a beautiful clarity.
On April 2, Watson and Crick submitted the first official text to the professional review Nature, which published it on April 25. The contrast is striking between the enthusiasm of Daddy's letter and the short and careful scientific release, not illustrated, soberly explaining that the fundamental breakthrough of the new theory is the relative position of the chemical elements in the molecule.
Their theory was right, and was soon validated by all biochemists in the world. Daddy's letter is a true treasure in the history of science, unparalleled except perhaps by some letters from Einstein. The estimate is quite open: $ 1M to 2M.

1961 From Sputnik 1 to Gagarin
2011 SOLD 2.9 M$ including premium
Sputnik 1 demonstrated in October 1957 the feasibility of orbital flights. It was only a small sphere of 58 cm in diameter, but the Soviets had other plans ready in their boxes.
Only a month later, Sputnik 2, a large conical capsule of 4 meters high and 2 meters in diameter at the base, established unequivocally that the goal of the Soviets was a successful manned flight.
The death of the dog Laika during the flight of Sputnik 2 showed that this test was premature. The Russians, embarrassed by this event, waited 45 years to confess that her death was due to excessive heat. Anyway, the martyred dog would not have passed the conditions of reentry.
Thereafter the program was held step by step. In August 1960, two dogs, a rabbit, two rats and 42 mice came back alive after a full day in orbit.
The Soviets were now ready to send the first cosmonaut in space. Becoming cautious, they made a last rehearsal on March 25, 1961, with the dog Zvezdochka aboard Sputnik 10. The success of this mission provided the green light for the flight of Gagarin on April 12, 1961.
Half a century has passed since that historic flight. On April 12 in New York, Sotheby's will sell the Vostok 3KA-2 capsule used for the Sputnik 10 mission. This prestigious carcass was emptied for a long time of its equipment. It is illustrated on the press release shared by Artdaily.
It is identical to Gagarin's capsule, and unique of its kind on the market. Its price is hard to predict. The auction house announces a very opened range of estimates: between 2 and 10 million dollars.

1962 The Invention of the Molecular Biology
2014 SOLD for $ 4.8M including premium
The birth of molecular biology is the result of a multidisciplinary cooperation between chemists, physicists and biologists. The existence of nucleic acids in the cell nuclei had been identified in the nineteenth century. From 1939, advances in micro-radiography X gave hope to understand the structure of these molecules.
Scientists had identified two types of acids, RNA (ribonucleic acid) in the cytoplasm of the cell and DNA (deoxyribonucleic acid) in the chromosomes. They appreciated that these acids held the key to the functioning of life.
Two British laboratories of crystallography worked collaboratively. Francis Crick, assisted by the young US doctor James D. Watson, was at Cambridge. In London, Maurice Wilkins was assisted by Rosalind Franklin who perfected the techniques of observation and realized the radiograms. The untimely cancer of Rosalind Franklin is probably due to an excess of radiation dose.
The single helix of RNA structure and the two strands of DNA were among the first discoveries. In 1953, Watson understood that the shapes of the elements of the two DNA strands were identical although these elements were different. Crick and Watson immediately developed the model of the double helix, which was the biggest breakthrough of all time in the field of life sciences.
The letter written by Crick to his young son showed that he was aware of the importance of the discovery. It was sold for $ 6,05M including premium by Christie's on April 10, 2013.
The Nobel Prize in Physiology or Medicine was awarded to Crick, Watson and Wilkins in 1962. Crick's Nobel medal and diploma were sold as a single lot for $ 2,27M including premium by Heritage on April 11, 2013.
Watson, now 86 years old, entrusted Christie's to sell his Nobel memories, offered in three lots on December 4 in New York. The Nobel medal with its case is estimated $ 2.5M, lot 1. His handwritten notes for the acceptance speech are estimated $ 300K,lot 2.
The manuscript of his Nobel lecture on the role of RNA in protein synthesis is estimated $ 200K, lot 3. Less than ten years after the discovery of the double helix, this theme highlighted the fact that the physicochemical mechanisms of life were already fully explained.
A portion of the proceeds from the sales will be donated by Dr. Watson to the benefit of scientific research and charities.

1982 The Equation of the Astronauts
2019 SOLD for £ 3.6M including premium
Throughout his career George Daniels has imitated and improved the most daring complications of pocket watches, often taking Breguet as an example. For the sidereal hour, his model was George Margetts, a contemporary of Breguet who worked in London. Daniels however did not emulate another remarkable specialty of Margetts, the tidal dial.
The equation of time is the difference between the apparent time, which can also be read on a sundial, and the sidereal time which takes its reference in the position of the fixed stars. This difference is an annual cycle due to the obliquity of the Earth and the ellipticity of its orbit.
The first pocket watch in which Daniels included the equation of time is his ninth opus, Elsom II, in 1975.
George Daniels was known for his wit. In 1979 he states that the accuracy of measurement obtained by Margetts, 1.8 seconds per year, is not sufficient for the control of time by an astronaut on his way to Mars. An astronomer from Cambridge University calculates for him a ratio between the two escapement wheels that will reduce the variance to 0.4 seconds per year.
The first pocket watch incorporating these new data is George Daniels' fifteenth opus, the Space Traveller, which also offers the annual calendar and the phases of the Moon. In 1982, shortly after finishing his Space Traveller, Daniels sold it to a collector, probably to meet a prior commitment.
Frustrated that he had parted away from his Space Traveller I, Daniels realized in 1983 the Space Traveller II, on which he added a chronograph and a thermometer. He did not let go this specimen that allowed him to behave like an astronaut in the salons. His fourth and last pocket watch to include the equation of time is the Grand Complication, in 1987.
The Space Traveller I is estimated £ 700K for sale by Sotheby's in London on July 2, lot 143. Space Traveller II was sold for £ 3.2M including premium by Sotheby's on September 19, 2017. Grand Complication was sold for CHF 2.4M including premium by Phillips on May 11, 2019.

1982-1983 George Daniels as a Sidereal Traveller
2017 SOLD for £ 3.2M including premium
On November 6, 2012, Sotheby's sold the collection of George Daniels including historical timepieces and watches from his invention. I discussed the latter group as pasted below :
Fascinated by watches, George Daniels chose to devote his professional life to them. A repair craftsman of great skill, he became a specialist of Breguet and then made his own watches with an increasing complexity.
In the era of quartz watches, Daniels managed to demonstrate that mechanical watches could still be fully competitive. His invention of the co-axial escapement which suppresses the need for a lubricant is one of the most important advances in watchmaking since Breguet.
In a career that began in 1970, Daniels has completed 37 watches made entirely in his workshop from elementary components to final assembly. Sotheby's devoted an exhibition to them in London in 2006.
Daniels was a lover of great mechanics. The remarkable Bentley Blower racing car sold for £ 5M including premium by Bonhams on 29 June 2012 came from his deceased estate.
I am listing below four watches from his personal work. These 2012 results include the premium.
Made circa 1982, the Space Travellers' watch including a double-wheel escapement was sold for £ 1.33M.
Made around 1987 the Grand Complication watch is a very good example of Daniels' co-axial escapement. It was sold for £ 915K.
As its name suggests, the First wristwatch made circa 1991 is a rare example of a wristwatch incorporating the co-axial escapement. It was sold for £ 385K. A more recent watch made in 1994 was sold for £ 660K over an estimate of £ 300K.
The Space Travellers' watch comes back to Sotheby's in London on September 19, lot 121 estimated £ 1.2M. It is a great opportunity to revisit its remarkable complication. Made in 1982 the only other example is simpler, without a chronograph function : the 2012 catalogue reminded that it was sold for CHF 220K by Sotheby's on November 17, 1988.
Based on a different denting of the two wheels Daniels had been able to realize a watch compensating at the will of the user the difference of 3.555 minutes per day between solar and sidereal times. Well aware that it was a sensational horological feat Dr Daniels exhibited it sometimes at events as a dress watch, stating that it was the suitable instrument to control the time in a long telephone conversation during a trip to Mars.
Please watch the video shared by Sotheby's before the 2012 sale.

1987 The Complications of George Daniels
2019 SOLD for CHF 2.4M including premium
The mastery of watchmaking by George Daniels equaled that of Breguet, whom he admired. In 1980, 157 years after the master's death, he is the first inventor to patent a basic innovation : his coaxial escapement reduces the friction to the point that mechanical watches no longer need a lubricant.
His watches were entirely hand made by himself. His understanding of mechanics was such that he made very few preliminary drawings for developing a new complication. In addition to the clocks and to a commercial series of 58 watches in 1999, he built during his career 23 pocket watches and 4 wristwatches.
His effectiveness was outstanding. The watches equipped with his coaxial escapement are reaching an accuracy below 1 second per month, better than any quartz watch in his time.
Built in 1987, the Grand Complication appears as the ultimate achievement of George Daniels' pocket watches, before he entered a miniaturization phase for creating wristwatches.
Daniels worked with his intuition under no other influence than Breguet. The Grand Complication includes mechanisms entirely invented by him for the annual calendar and for the repeating of minutes. Built on a one-minute coaxial escapement tourbillon, it also offers the moon phases, the power reserve indicator, the equation of time and even a bimetallic thermometer, all of that in a 62 mm diameter case. The dial is highly readable.
Daniels died in 2011. In the auction of his collection by Sotheby's on November 6, 2012, the highest price rewarded the Space Travellers watch, sold for £ 1.33M including premium over a lower estimate of £ 400K. In the same auction room on September 19, 2017, it reached £ 3.2M including premium.
In the 2012 sale the Grand Complication was estimated £ 500K, thus being announced as the most important of Daniels' prototype watches. It had been sold for £ 915K including premium, lot 10. It is now on sale by Phillips in Geneva on May 11, lot 34.

2018 Sympathique with the Rubidium
2019 SOLD for $ 2.9M including premium
The advancement of timekeepers includes the complications, of course, but also the search for the best accuracy. In the last century, for George Daniels, Abraham-Louis Breguet remained the absolute reference for mechanical watchmaking. Urwerk, a Swiss brand created in 1997, takes over.
One of Breguet's most avant-garde designs was the Breguet Sympathique, a pocket watch that did not need to be touched for winding, time setting and regulation. When its power reserve approached depletion, it was inserted into a clock to which it was mechanically coupled. The word Sympathique is an evocation of the coupling, by its etymology meaning 'functioning by affinity'.
Obtaining the three settings simultaneously was a mechanical feat that was achieved by his workshop for the duc d'Orléans in 1835, twelve years after Breguet's death. Restarted to working condition by Daniels in the 1970s, the complete system was sold for $ 6.8M including premium by Sotheby's on December 4, 2012.
The Urwerk AMC (Atomic Mechanical Control) system unveiled in 2018 at Baselworld Miami is an adaptation of the Sympathique to the modern technologies. Without a direct application identified, this technical feat paves the way for new developments.
The time reference is provided by a 45 x 30 x 18 cm atomic clock weighing 35 Kg. It uses the quantum energy transitions of the rubidium atom, known by physicists to provide the best stability with a 1 second error for 317 years when it is associated with a garnet of yttrium and iron. It provides the stability of a wristwatch by coupling, without manual winding, without quartz, without battery.
Urwerk announced the production of the system in three units. A price of $ 2.7M was announced in period on the web by a specialized website. The titanium mechanical watch with the serial number 001 associated with its atomic clock is estimated to exceed $ 1M for sale by Phillips in New York on December 10, lot 8.
