Model: System One (DTS103-53-02) Gender: Unisex Frame Size (mm): Lens Width Bridge Temple 53 19 143 Frame Materials: Titanium, Acetate Frame Description: Meticulous craftsmanship and bold design join forces in System-One, an exuberant "navigator" style that unites the spirit of a classic aviator with the shape of a traditional square lens. The frame's muscular details evoke the tatara ironworking method that allowed early Japanese blacksmiths to forge elaborate creations from clay blast ovens; their legacy would go on to inspire a generation of modernist designers - most notably the esteemed architect Frank Lloyd Wright - to incorporate Japanese craftwork into the structures, furnishings, and objects of the early 20th century, which influenced the frame's etched temples and intricately sculpted end-pieces.
