All the elements of the movement are especially assembled at the St Blaise/Neuchâtel Manufacture. Invented by three Swiss engineers René Quinting Willy Cleusix and Norbert Perucchi the unique "Quinting" watch is inspired by the principle of transparency which has fascinated watch and clockmakers ever since Robert-Houdin invented his "Mystery Clock" in the 19th century. Today that clock has become modernized in the form of a wristwatch. The first See-Through Watch was launched in 1999 after 7 years of research. Its technical and esthetic value was immediately recognized.
