Atmos - The clock that lives on air

Leonardo da Vinci may have been able to demonstrate the physical impossibility of constructing a perpetual motion machine, but that hasn’t stopped people from continually trying to do so. In 1928, for example, a Neuchatel engineer called Jean-Leon Reutter built a clock driven quite literally by air. It took the Jaeger-LeCoultre workshop a few more years to convert this idea into a technical form that could be patented, and to perfect it to such a degree that the Atmos practically achieved perpetual motion. The technical principle is a beguiling one: a hermetically sealed capsule is filled with a gas which expands as the temperature rises and contracts as it falls, making the capsule move like a concertina. This motion constantly winds up the mainspring, a variation in temperature of only one degree in the range between 15 and 30 degrees centigrade being sufficient for two days’ operation. To convert this small amount of energy into motion, everything inside the Atmos naturally has to work as smoothly and quietly as possible.

The balance, for example, executes only two torsional semi-oscillations per minute, which is 60 times slower than the pendulum in a conventional clock. So it is not surprising that 60 million Atmos clocks together consume no more energy than one 15-watt light bulb. All its other parts, too, are not only of the highest precision. Admirers of advanced technology, however, are not the only ones who get their money’s worth.

Connoisseurs of elegant forms, precious materials and traditional craftsmanship do so as well, because every Atmos is still made entirely by hand. With some models a single clock takes a whole month to produce, not counting the five weeks of trial and adjustment that every Atmos has to undergo. Only then are Jaeger-LeCoultre master-watchmakers satisfied enough to authenticate an Atmos clock with a signature and allow another one to leave the workshop.

Subsequently, many end up in the very best of homes, because for decades the world’s most celebrated watchmaking country has been presenting its distinguished guest with this masterpiece of Swiss artistry. The Atmos has had the honour of associating with great statesmen, royalty, and other renowned people including President John F. Kennedy, Sir Winston Churchill, General de Gaulle and Charlie Chaplin.

The proprietors Father and Son, John and Mark Coxhead have a combined passion for collecting clocks and have turned their dream into a very successful business dealing in quality restored clocks. This family business established 18 years ago is located from a pretty 19th century shop in the Kings Road, Chelsea, London. This prestigious area is world renowned for fine quality antique shops and fine art galleries.

Mark and John have been selling and restoring clocks for the last 18 years and because they have a large amount of stock always for sale in their showroom they see a big cross reference of antique clocks having restored their own showroom clocks as well as customers clocks. They restore the clocks for the British Home Office and for the Royal Lifeguards, Hyde Park. We are also proud to have sold clocks to members of the British Royal Family.

All their clocks are restored by themselves and come with a full years guarantee in the UK. They also stock a wide selection of carriage and wall clocks ranging from unusual English station wall clocks to fine Regency period drop dial clocks.  Also they carry a variety of interesting French period carriage clocks ranging from simple timepieces to repeaters. All their carriage clocks have the original platform escapements and not replacement modern ones.
