Large, rare and unusual Dent (Fred Whitlock) 'Concorde', Grasshopper escapement, weight driven, single wheeled skeleton clock.

Exceptionally rare and unusual 20th century large weight driven skeleton clock.

Stock No:   14030

Electrically wound, weight driven, remontoire operated, single wheel movement with a two-and-a-half-second beating, large compound pendulum and John Harrison's silent Grasshopper escapement. Also having unique 'without motion work' jumping hands.

The large, heavy gauge movement plates were designed on the Concorde aircraft Delta wing shape and have five large pillars. The hour and minute wheels are operated independently by a set of 'Dog' levers and the 'reserve power' weights are wound via a chain automatically every few minutes by a small Swiss, mains powered electric motor and operated by a mercury tilt switch. The weights are situated behind the backplate and 'load' a Remontoire spring at intervals that in turn drives the single large escape wheel. The large Grasshopper escapement is clearly visible and is fixed to the massive, slow swinging hypnotic 24 inch long pendulum that is pivoted centrally on knife edges and has a solid brass ball on each end.

The movement is sat on a polished mahogany stepped base and is covered by a large glass case however, the clock can be run with this removed.

The 'Concorde' clock was commissioned in the early 1970's by Dent of London as a limited number and produced by Fred Whitlock on an improved design similar to what is believed to be that of Martin Burgess.

It is believed that 25 Concorde's were produced and sold by Dent and upon Mr. Whitlock's retirement the parts for a further 10 were purchased from him by us. We have purchased one of the original 25 which we are currently 'correcting' and offer for sale. It is thought that these clocks were sold for £2,000.00 each in the early '70's. We sold the remaining 10 for £8,000.00 plus V.A.T. each, 30 years later. There are 35 of these rare clocks in existence plus the prototype and a larger example that we made to commission. We know the whereabouts of 12 of them. To date, only 2 examples have been sold at auction and have realised good prices.

This is a rare opportunity to purchase a unique, extremely rare concept clock that never needs winding manually and is not only a timepiece but a living piece of art. The quality is first grade and it is unlikely that there will ever be more than 35 of these clocks in the world because of the cost of manufacture. The 'Concorde' clock is featured in 'British Skeleton Clocks' by Derek Roberts.

*These clocks were developed from 1969 to 1972 and it is believed that 100 were commissioned by Dent from Mr. Fred Whitlock however, because of the complexity of this new concept clock, they unfortunately had inherent faults. I was told by Mr. Whitlock that Dent were not sympathetic to the situation and therefore abruptly cancelled the order after only 25 had been delivered. We purchased the further examples in various stages of manufacture and assembly and carried out further, extensive development. We worked closely with Mr. Whitlock and overcame all the technical issues related to the clocks. We have had several original examples in our workshops and have successfully 're-engineered' them. As is so often the case, a fabulous example of British ingenuity was short lived because adequate research and development could not be afforded. Hopefully, as the world's experts on these clocks, we can now allow such rare artistic pieces to successfully run reliably for generations to come. These are large, high quality, aesthetically 'perfect' and formidable clocks. They look stunning - unlike anything most have seen before! This 'Concorde' appears to be the only complete example for sale in the world.
