N2  - "Epmosphere" is the Franco-Swiss project for the renovation of the moving sphere clock in St. Petersburg by the watchmaking schools of Morteau and Porrentruy. This sphere is a rare planetary clock (there are only three to four examples in the world), made in France in the 18th century and whose condition required repair and the making of missing parts
