The 21st SIHH from January 17th to 21st 2011 will welcome 19 exhibitors, the same number as in 2010, in 30,000 sq m of floorspace at Palexpo, Geneva. The Beyer Clock and Watch Museum in Zurich will show some eighty of the most significant pieces from its collection, in an exhibition that traces the history of time measurement from the sundial to the twentieth-century wristwatch. A richly illustrated catalogue in French, German and English will accompany the exhibition.
