Jean Perret now adds rectangular models to its extra-thin “Slim Line” collection, probably the slimmest designs available in their price range. Their 10-micron goldplated cases are only 4.20 mm thick, fitted with a 10-micron goldplated bracelet or a leather strap. Swiss quartz movements. (JEAN PERRET “Slim Line”)
