2011: Atmos 561 by Marc Newson, unique piece

Invented in 1928 by the Neuchâtel engineer Jean-Léon Reutter, developed and manufactured by Jaeger-LeCoultre, the Atmos perpetual clock flirts with one of humanity’s oldest dreams: perpetual motion. Drawing its energy from the slightest changes of temperature, it consumes 65 million times less energy than a 15-Watt light bulb.

A change of one degree is enough to run the clock for 48 hours. Having served as the official gift of the Swiss government for over half a century, the Atmos has become an emblem of Swiss watchmaking excellence, and a cult object for its many fans. The Artcurial sale will offer several very rare models from the 1930s. For its part, the Jaeger-LeCoultre Manufacture is offering a unique piece especially made for this sale, with the proceeds to be donated to a charitable association, the AMM (The Monaco Association against Muscular Dystrophy).

The Atmos 561 by Marc Newson is housed in a special Baccarat crystal case the making of which required a number of special operations, in particular the technique of glass frosting, followed by the application of several acid baths to obtain a sand-blasted crystal effect.


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.
