1907: The world's thinnest movement

The collection of ultra-thin calibres designed in response to the challenge made in 1903 by Edmond Jaeger to Jacques-David LeCoultre is among the most extraordinary in watchmaking.

It includes several minute repeaters, chronographs, and double complications. But the most famous creation is still the LeCoultre 145 Calibre, produced from 1907 until the 1960s in some 400 copies, only 1.38 mm thick, which made it the flattest mechanism of its time.


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.
