Pierre DeRoche: Mysterious Story about Movement

Ann — Fri, 12 Feb 2010 08:23:55 +0000

In 2007 the managing director of Pierre DeRoche Pierre Dubois found in his friend’s antique shop an interesting movement that used to power a pocket watch of the 19th century. He bought the watch and brought it to his father. From the very beginning the watchmakers were certain that it was a LeCoultre movement, but they couldn’t prove their guess. The only clue in the investigation of the movement’s story was the patent number 8172 on the main plate. In the Swiss federal register this number corresponded to a “new watch with a crown”. The patent was given on May 5, 1894, to some Noma Robert-Vaelti, a watchmaker from La Chaux-de-Fonds. But neither reputable historians of horology nor specialists from the watch museum in La Chaux-de-Fonds knew this watchmaker.

The watchmakers from Pierre DeRoche decided that the story of the movement is as follows: at the end of the 19th century the movements by LeCoultre were sold to many renowned brands, but unknown watchmakers could buy them too – like for example the mysterious Noma Robert-Vaelti. He improved the movement he had bought and patented it. Later the watchmakers managed to find the small seal of LeCoultre – a tiny engraving on the movement.

Pierre Dubois decided to present the old movement with a new life. The result of his work is the new Pierre DeRoche Grand Cliff TNT BelCanto powered by the unique antique movement carried to perfection in the workshops of the company. The watchmakers from Pierre DeRoche not only re-assembled the movement but also decorated it with Cotes de Genève. In total the company produced only three copies of the watch: with antique movement, with repeater and quarter-of-an-hour gong and with chronograph.

Rudis Sylva Harmonious Oscillator

Ann — Fri, 29 Jan 2010 11:03:52 +0000

Mika Rissanen, the watchmaker specializing in design and creation of complicated movements, has designed a new revolutionary watch system for the Rudis Sylva brand.

The new movement boasts two tooth balance wheels that are operated by one escapement mechanism. The wheels are connected with each other and guarantee the same amplitude. With innovative technicity, this design can boast a more accurate setting capacity than a conventional tourbillon, thanks in particular to the asymmetric deployment of the mainsprings in all positions, hence the name “Harmonious Oscillator“. This world first with two toothed balances exhibits a resonance effect from the first oscillations. The tourbillons run inside a cage with pure but stylised decorations.

The uniqueness of the new Rudis Sylva movement is enhanced by the perfect shape that houses the timepiece’s heart: the case is crafted from gold or platinum. The case back is decorated with an enamel image of the sundial. This dial is a reproduction of that adorning the wall of the “Les Rosées” farm, in the village of Les Bois, formerly known as Rudis Sylva.
