Wrist Watch | Table Clock deutsche Version


A new concept consisting of design and technique for ‘squaring the circle’

Square Circle

Having developed this watch for many years, I can now present it to you as a hand made piece of my creativity.

I succeeded in compressing the hypotrochoid gearing, which is my own patented development, into the size of a wrist watch. The hour indicator runs in a mysterious way as a blue dot of sapphire (cabochon) on a square course without being visibly connected to the centre. Animation

Apart from the fascinating technology the geometrical basic forms of ‘square’ and ‘circle’ are also brought into the design of the watch. Inspired by the Art Déco style I designed an unusual wrist watch, which has its special appeal through the combination of linear and circular elements.

I would like to thank especially Philippe Dufour and Frank Jutzi, my ‘godfathers’ at the AHCI (Académie Horlogère des Créateurs Indépendants), for their helping support.
