1929: The world's smallest movement

In 1929, at a time when demand for luxury objects had dwindled because of the international economic crisis, the Manufacture’s watchmakers set themselves the challenge of creating the world’s smallest watch movement.

They miniaturised the Duoplan calibre to the limit. The Calibre 101 weighed barely one gram and had 74 parts. Crafted in extremely small quantities, but in continuous production, its record is still unmatched to date. For her coronation in 1953, Queen Elizabeth II of England wore a watch that used this superlative mechanism.


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.
