A Detailed Look the George Daniels Space Traveller I

space traveller's watch i

The Space Traveller II is the most famous George Daniels pocket watch, having set the record for a Daniels timepiece when it sold for the equivalent of US$4.32m two years ago .

Not only is it an exceptionally valuable watch, the Space Traveller II is mechanically intriguing, being driven by an independent double-wheel escapement. That in turn allows for twin time displays, of both mean solar time, which is the conventional, 24-hour day, and sidereal time, measuring using Earth’s rotation relative to fixed stars.

The second Space Traveller was a watch Daniels kept until the end of his life, along with the recently sold Grand Complication .

The first Space Traveller, on the other hand, disappeared from public view after it was sold in 1988. When asked about the watch recently, Daniels’ protege Roger W. Smith responded that he has never encountered the original Space Traveller – until now.

When Daniels finished the first Space Traveller in 1982, it was sold by English antiquarian watch dealer Bobinet. The buyer subsequently sold the watch at Sotheby’s in Geneva on November 17, 1988, for 220,000 Swiss francs.

The collector who paid what was then a world record price for a watch was late German billionaire Erivan Haub , who was once the fifth richest man in the world according to the 1992  Forbes  rich list. A dedicated collector, Haub owned one of the world’s most important collection of pocket watches – totalling over 800 timepieces.

Sotheby’s will soon sell Haub’s collection, which has been named Mastery of Time , over several auctions . The Space Traveller I is part of the first sale that takes place in July 2019 at Sotheby’s London, and despite a modest estimate of £700,000-1.0m, it will undoubtedly finish as the most expensive watch of the collection.

The origins

The first Space Traveller came about after Daniels had completed five pocket watches – entirely hand-made as all Daniels watches were – equipped with the independent double-wheel escapement that he invented in 1974 with the help of the Derek Pratt, a lesser known but equally talented watchmaker .

Inspired by Abraham-Louis Breguet’s short-lived échappement naturel , or “natural escapement”, the Daniels independent double-wheel escapement features twin escape wheels with a detent in-between, each powered by its own barrel and gear train. Because the contact between the escape wheels and detent is tangential, the escapement operates with almost zero friction.

The barrels and gear trains mirror each other, explaining the symmetry of the movement

But as Breguet discovered two centuries before, the independent double-wheel escapement was a dead end, being too tedious to manufacture, assemble, and maintain.

Daniels instead moved on to the co-axial escapement that is now synonymous with the Daniels name. He spent several years refining the invention, and also fitted it to several of his watches, including the flagship Grand Complication, before finally selling it to Omega.

It’s likely at least a million Omega watches with the co-axial escapement have been produced since the first ones rolled off the production line in 1999, proving the longevity and practicality of Daniels’ invention.

Notably, the independent double-wheel escapement recently made it into a wristwatch, over four decades since Daniels first realised it. The escapement was miniaturised for the first time by Charles Frodsham and installed in their Double Impulse Chronometer Wristwatch  that was launched last year.

Before the Space Traveller watches, the very last pocket watch Daniels constructed with the independent double-wheel escapement was sold to the late Theodore Beyer, the seventh generation of his family to run watch retailer Beyer Chronometrie, which is now run by his son Rene.

Writing in his autobiography, All in Good Time , Daniels described Beyer as “a most serious collector of watches”. He also recounted a 1978 dinner with Beyer in Zurich, where Daniels was carrying the fifth pocket watch featuring the independent double-wheel escapement he had made; the first had been commissioned by Illinois millionaire Seth Atwood , an obsessive collector who founded the now defunct Time Museum of clocks and watches.

“During the course of the meal [Beyer] demands to see what I was wearing… he asked if he could buy it… He was adamant that he would not go home without it.” Daniels relented, because “I could, after all, make another.”

Twin trains, twin times, and a lot of math

And make another he did. As he explained in All in Good Time , “It occurred to me to make a solar/sidereal watch utilising the same principles of design but with separate calculations for each train.”

In short, he envisioned a movement with the independent double-wheel escapement but with a different time display for each going trains, an idea that took four years to realise.

Though Daniels himself managed to design a sidereal gear train with an error of just 1.27 seconds a year, he thought “there might be a better solution” as he put it in his autobiography. So he approached a friend at Cambridge University in search of a mathematician who could help him perfect the going train.

He was then introduced to Dr Henry Ellis Daniels, a prominent statistician who also happened to be a watchmaker. Dr Daniels was able to respond with “a better solution within days, and modestly claimed he had found the answer in a book.” The solution was an error of just 0.4 seconds a year.

As a result, Daniels named the watch Daniels Squared, in acknowledgement of Dr Daniels’ contribution. But the watchmaker also christened his creation the Space Traveller’s Watch, a catchy name that was a reference to the then recent 1969 Moon landing.

Achieving the 0.4 second deviation per year required deft calculation and subtly different gearing for each going train. Although each wheel train has the same layout and operates on identical principles, they are minutely different.

Both going trains have identical barrels, centre and third wheels. While the mean solar time train continues as in a conventional movement, Daniels opted to insert an additional wheel between the seconds and escape wheels on the sidereal train in order to change its gear ratios.

That also allowed for a sidereal time seconds hand on the dial, but more importantly optimised the reliability of the movement by avoiding having to use wheels with large number of teeth further up the gear train.

Although they look identical when examined through the display back, the twin escape wheels are different – that on the sidereal train has 14 teeth, while the escape wheel for mean solar time only 13.

For the aesthetics of the watch to fit the movement he devised, Daniels looked to Breguet, unsurprisingly. Specifically, he was inspired by the 19th century Breguet pocket watches no. 2807, 3862 and 3863.

In fact, it was possible that Daniels himself had worked on pocket watch no. 3862 when he worked at Breguet in Paris when it was owned by the Brown family. Now in the Breguet Museum, watch no. 3862 was started between 1821 and 1824, then left unfinished until it was completed and sold in 1968.

Watch no. 2807 is in the Patek Philippe Museum, having sold for 2.26m Swiss francs in 2002, while watch no. 3863 is in a royal collection in the Middle East, most likely that of the Sultan of Oman.

All three watches have a dial layout similar to the Space Traveller, with symmetrically placed twin sub-dials, one for mean solar time and the other for apparent solar time, along with Sun and star emblems for each. The crucial purpose of these watches was to display the equation of time – the difference between mean solar time, or the standard, 24-hour day, and apparent solar time, or the day according to the movement of Sun.

But the three watches are all powered by a single barrel and going train. Daniels, in other words, invented a new movement incorporating Breguet’s natural escapement to suit the 19th century watchmaker’s dial design.

The Space Traveller I returns

Although unseen in public for almost 31 years, the Space Traveller I is well known enough that it has almost become mythical. Such exalted status might be a set-up for disappointment if the watch doesn’t live up to its reputation.

Fortunately the Space Traveller I is impressive in the metal. It is a large watch at 62mm in diameter, and entirely in 18k yellow gold. Though the watch is weighty, the case is relatively slim, giving it a refined profile.

george daniels first space traveller watch 1

The hallmarks inside the case that indicate it is 18k gold, imported into the United Kingdom, and hallmarked in 1983.

Visually it is typical of Daniels designs, which was in turn heavily inspired by Breguet. It is made of solid silver that’s been finely engine-turned, with all the markings engraved by hand.

george daniels space traveller I watch 2

The dial is characterised by several sub-dials, but arranged symmetrically, with all elements sensibly laid out and legibly styled.

george daniels space traveller 1 watch 19

Executed with Roman numerals and gold hands, the right sub-dial displays mean solar time – hence the tiny gold Sun right above it – and the aperture on its lower edge is an annual calendar, showing the day of the month on a ring scaled for the full year. The calendar advances twice per day as the hands turn.

george daniels space traveller 1 watch 22

Denoted by a tiny silver star, the sub-dial on the left is for sidereal time, where a day is approximately 23 hours, 56 minutes, and 4 seconds. It is shown on a 24-hour dial with Arabic numerals matched with blued steel hands, easily setting apart the two time displays.

george daniels space traveller 1 watch 23

Incorporated into the sub-dial is a moon phase display, and on the lower edge of the sub-dial, the age of the moon indicator, or in other words, the day of the month. Like the calendar, the moon phase display advances twice per day.

george daniels space traveller 1 watch 18

At 12 o’clock on a fan-shaped display is the equation of time, which is the difference between mean solar time and apparent solar time, which is time based on the orbit of the Earth around Sun.

george daniels space traveller I watch 12

The movement mirrors the dial in its symmetry and sensibility. Twin barrels sit at the top of the movement, with each wheel train flowing downwards to its own escape wheel, which meet under the large balance wheel.

A key made of blued steel and gold – attached to the watch by an appropriately intricate gold chain – accomplishes both winding and setting. The wide end of the key inserts into the large socket and wind both barrels simultaneously, while the narrow end is used for setting the individual indicators.

Winding is done counter-clockwise as indicated by the arrow

Mean solar time is set via the socket above “Daniels” on the going train bridge, while the sidereal time socket is on the opposite end of the bridge, engraved “London”.

And just below each end of the train bridge are two additional, smaller sockets for the calendar and moon phase respectively, both of which can only be set clockwise.

george daniels space traveller 1 watch 29

If there is one shortcoming in the Space Traveller I, it is the mechanical and visual similarity between it and the preceding five watches with the independent double-wheel escapement. Though unique, the first Space Traveller does have some close relations.

With the second watch now safely residing in the United Kingdom, and unlikely to reemerge in public for a lifetime, it is no longer possible to compare the two Space Travellers. But the differences between the two are well known, thanks to Daniels’ own archive and commentary over the years by his successor Mr Smith.

One crucial complication separates the two watches – the Space Traveller II has Daniels’ “compact chronograph”, while the first version does not. That is obvious through the single display back of the second Space Traveller; notably, the Space Traveller I has a display back under a hinged hunter back.

george daniels first space traveller watch 3

More intriguingly, the chronograph can be switched between the two trains, meaning it can record either elapsed mean solar time, or elapsed sidereal time, thanks to a clutch visible in the centre of the movement.

Invented by Daniels and premiered in the second Space Traveller, the compact chronograph was later built into two other watches, including a wristwatch that also featured a tourbillon .

So named because it was designed to occupy minimal space, the compact chronograph was constructed on top of the movement.

Compared to the first Space Traveller, the second has a narrower and thinner going train bridge, so as to accommodate the chronograph mechanism. It also meant the repositioning of the balance cock, which is vertical in the first but becomes a horizontal bridge in the second.

Despite those changes, along with several other smaller tweaks, the two movements are share the same basic construction, with the key components remaining in the same position on both base plates.

Concluding thoughts

The Space Traveller I is unquestionably an important and valuable timepiece, but is it more valuable than the second Space Traveller?

While the Space Traveller II is more complex and mechanically compelling, the first version has a functional elegance that embodies the lineage from Breguet to Daniels.

george daniels space traveller 1 watch 32

The Space Traveller I was also the first one built, which is usually matters as watches go, hence the value of an earlier Royal Oak A-series versus one with a serial number over 1000.

That, combined with the overall rise in values of Daniels watches since his passing, as well as the heavy hitters reputedly interested in the watch, will likely see the Space Traveller I sell for as much, if not more, than the second version.

George Daniels Space Traveller I Watch Sold For £3.6m, Record for World's Most Expensive English Watch

George Daniels (1921 - 2011), a legendary horologist, created the one-of-a-kind Space Traveller I watch in 1982. And just yesterday, the watch was sold in London for over £3.6m (US$4.6m), breaking the world auction records of an English watch as well as of an independent watchmaker.

Many are familiar with luxury watch producers like Rolex and Patek Philippe but very few might have heard of the name George Daniels. To find out how his watch achieved such an extraordinary price, we must get to know the story of this outstanding watchmaker.

George Daniels

Born in 1926, George Daniels came from a working-class family in London, suffering through poverty and abuse in his early years. The only place where he found joy was in the mechanics of timepieces. In 1944, Daniels joined the British army and left in 1947.

With only £50 of gratuity in his pocket, Daniels bought some tools and became a watch repairer. He also attended horology classes at night to improve his skills. After a decade of hard work, in 1960, he finally opened his first watch repair and cleaning shop in London. Daniels was particularly interested in the works of the early 19th-century French watchmaker Bruget and soon became an expert on Bruget. 

Daniels started out as a watch repairer

Draft of the Space Traveller coaxial escapement design 

Meanwhile, Daniels became good friends with Sam Clutton, who was a vintage watch dealer. Daniels began to investigate into expensive handcrafted watches, and under Clutton's convincing, he embarked on a journey of watchmaking. In 1969, Daniels sold his first handcrafted pocket watch to Clutton for £2,000.

One of the most prominent achievements of Daniels was creating the coaxial escapement in 1974. Traditional escapements had to use lubricants but this eventually caused problems with accuracy as oil thickened over time. However, the coaxial escapement used radial friction instead of sliding friction, making lubricants unnecessary. This design was widely used in the 1990s Omega watches.

Throughout his life, Daniels only produced 23 watches, Space Traveller I being one of them. Created in 1982, the name of the watch pays tribute to the NASA Apollo missions.

Daniels expressed his interest in space exploration in an interview, saying that space technology is the world's most advanced technology and hoped to become part of it. He incorporated the mean-solar and sidereal times, age and phase of the moon as well as the equation of time indications in the Space Traveller I for the needs of astronauts. 

Dial with Arabic numerals located on the right shows the sidereal time, dial with Roman numerals shows the mean solar time; second dials are located below

Space Traveller's design layout 

Solar time is the time system that we use, measured according to the apparent time and the path of the sun, which means that a solar day is 24 hours long. Sidereal time is measured according to how long it takes for the sun to rotate a full circle which takes 23hrs 56m 4.1s.

As the Earth's axis of rotation is tilted, there is a time difference between the actual times of sunset and sunrise and the time shown on the watch. Therefore, the inverted fan-shaped dial on the watch shows the time difference, according to different seasons. The largest difference is 16 minutes. 

Space Traveller II sold for £3.2m in 2017

With such a delicate and complicated mechanism, Space Traveller watches are unique in their design and extremely valuable. In 1982, Daniels sold Space Traveller I to a collector but quickly realised that he regretted it. In the following year, he produced another one named Space Traveller II.

The present Space Traveller I was first auctioned in Sotheby's Geneva in 1988 for CHF220,000 (US$222,987). 30 years later, its price has soared to over £3.6m (US$4.6m) which is almost 30 times its previous selling price.

As to where the Space Traveller II resides, the watch had been in Daniels' collection until his death in 2011. In 2017, Space Traveller II was sold in Sotheby's London for £3.2m, setting the auction record for an English watch at the time. The record is now replaced by Space Traveller I.

space traveller's watch i

Sotheby’s to sell one of the world’s “most important” watches

George Daniels' Space Traveller I watch up for auction at Sothebys

One of the world’s most important watches could sell for more than $1 million when it goes up for sale at Sotheby’s in London next month.

Made in 1982, the Space Traveller I pocket watch has been described as “one of the most important watches of modern times”.

The timepiece is the work of George Daniels, the British horologist widely regarded as the greatest watchmaker of the 20 th century.

Offered from one of the world’s pre-eminent watch collections, the Space Traveller I will cross the block on July 5 with an estimate of £700,000 – £1 million ($900,000 – $1.2 million).

The original Space Traveller I pocketwatch, estimated at $900,000 - $1.2 million

George Daniels (1926 – 2011) built just 23 pocket watches throughout his remarkable career, and the Space Traveller I is considered perhaps the most significant.

Daniels originally conceived the watch as a tribute to space travel, which had inspired him during the 1960s, and set about creating a timepiece which could be useful to an astronaut.

To this end the Space Traveller I features both normal mean-solar time and sidereal time – the standard used by astronomers, based on the amount of time it takes the Earth to turn on its axis.

It also includes Daniels’ famous independent double wheel escapement, a mechanism which enables a watch to remain highly precise without the usual large number of wheels and trains.

Once completed in 1982, Daniels treasured the watch and often wore it to showpiece events. However, that same year he was persuaded over dinner to sell it to a private collector.

The watch is regarded as perhaps Daniels' finest work, and has remained unseen in public for over 30 years

He regretted the decision almost immediately, and swiftly began working on a replacement – the Space Traveller II – which remained in his personal collection as one of his most treasured watches until his passing in 2011.

In December 2017 the Space Traveller II sold at Sotheby’s for $4.3 million, almost doubling its pre-sale estimate.

The Space Traveller I passed through the hands of two collectors before being acquired by a third in 1988, during a Sotheby’s auction in Geneva.

For over 30 years it has remained unseen in the same private collection, the entirety of which will now be sold at Sotheby’s across four sales in London, Geneva, Hong Kong and New York.

“For me, ‘Masterworks of Time’, as we’ve called it, is absolutely one of the best private collections ever formed,” said Daryn Schnipper, Chairman of Sotheby’s International Watch Division.

“It is a collection put together by someone who wanted to tell the story of time through watches; someone who knew his subject, trusted his eye, and had a real sense of what was ground-breaking, both in terms of technology and of artistry. It’s a collection that’s unrivalled in its scope and breadth.”
