The Greatest Horological Inventions of All Time: Why George Daniels’ Co-Axial Escapement Revolutionised Mechanical Watchmaking

Editor’s Note: Today, the final installment of The Greatest Horological Inventions of All Time. Here, Andrew Canter examines the story behind the co-axial escapement, invented by George Daniels, industrialized by Omega, and now considered one of the great watchmaking innovations of all time.  You can find more of Andrew’s work at the Mr. Watchmaster website here. George Daniels (1926 – 2011) was raised in London in poverty. Aged five, he pried open his family’s alarm clock and realised that it was a metaphor for his life – always moving inexorably onwards, but without outside assistance. He was determined to learn horology, despite his parents’ opposition. He was conscripted into military service in 1944 which unleashed his innate mechanical skills, and following the end of the war, he studied horology, while repairing watches in North London.  He gained access to the work of the greatest watchmakers, particularly Abraham-Louis Breguet, through a meeting with a collector, and when it seemed that quartz technology would overwhelm traditional watchmaking, Daniels ensured this would not come to fruition. He made a series of increasingly ingenious mechanical watches, heavily influenced by Breguet, teaching himself to make every part, now referred to as the ‘Daniels Method’. Essentially, he devised a virtually oil-free escapement – the now iconic co-axial escapement – which was later mass-produced by Omega. It was anything but an easy journey, but George D...

Larcum Kendall and K1: The Greatest Watchmaker and Watch You Have (Probably) Never Heard Of

You may have heard of a few or more of the following historical people and events: Thomas Mudge, George Graham, John Harrison, the Longitude Prize, Captain James Cook, and the mutiny on the 'HMS Bounty.' However, you are less likely to have heard the name of a horologist who played a pivotal role in all of the above: Larcum Kendall (1719–1790). Come with me on a worldwide adventure involving timekeeping and history.

Hands On: Urban Jürgensen and Derek Pratt Oval Pocket Watch

A storied example of artisanal independent watchmaking, The Oval was the masterpiece by Derek Pratt (1938-2009), perhaps the greatest unknown watchmaker. Pratt began work on the Oval in 1982 as his magnum opus, the ultimate realisation of his aesthetic and technical vision. While his work for Urban Jürgensen is perhaps his best known, Pratt was an independent watchmaker with a diverse repertoire, including working with George Daniels on the co-axial escapement. Amongst his creations was a replica of John Harrison’s H4 marine chronometer. These projects, as well as the fact that the Oval was mostly hand made, meant the pocket watch took some two decades to complete. Although it’s a sizeable watch, the Oval is finely detailed, reflecting the high level of Pratt’s craft and the years he invested in creating the watch from scratch. Beyond its artisanal execution, the Oval also stands out for its technical achievement. Besides a detent escapement, the Oval also contains a horological first – a constant force mechanism integrated within the tourbillon – along with a thermometer, power reserve display, and moon phase on the dial. We took an in-depth look at the Oval in 2021, thanks to its current owner, Dr Helmut Crott. But now as the Oval heads to the auction block at Phillips, it’s worth one last look before it disappears into a collection. A two-decade odyssey A contemporary and friend of George Daniels (1926-2011), Pratt was one of the most talented horologists o...
