Designed for Winter 2013 collection, Classic Structura is characterized by skilled metalwork on the Francis arms inspired by early 20th century constructions. This model matches cold, unpolished silver metalwork with a sleek black acetate for a particularly rough industrial appeal. Classic Structura sports lenses by ZEISS in black. The box contains a soft case and a cleaning cloth. Size: R Lens Width: 55mm Frame Front: 140mm Frame Side: 145mm Product Code Size R: NQS
