John C. Ermel ‘Square Circle’

At Baselworld 2008, John C. Ermel unveiled his new concept ‘Square Circle’, which he presented for the first time two years ago at the stand of the AHCI (Académie Horlogère des Créateurs Indépendants) in the form of a table clock, was miniaturised. He succeeded in compressing this hypotrochoid gearing, which is his own development, into the size of a wrist watch. In a mysterious way the hour indicator runs as a blue dot of sapphire (cabochon) on a square course without being visibly connected to the centre.

‘Square Circle’ Watch

Apart from the unique technology the geometrical basic forms of ‘square’ and ‘circle’ are also brought into the design of the watch. Inspired by the Art Déco style of the ‘Roaring Twenties’, John C. Ermel designed an unusual wrist watch, which has its special appeal through the combination of linear and circular elements. One of the icons of that exciting time is the legendary Chrysler Building in New York. The triangles on the bezel and at the minute hand are a tribute to it.
