The Sixties Square Chronograph was first introduced in 2009, bringing a fresh twist to the iconic 1960's design. Glashütte Original then expanded the collection in 2017, offering new versions with unique dials in vibrant colors and textures, reminiscent of the classic round Sixties models. One such model, the Reference 1-39-34-24-32-04, boasts a striking red dégradé dial with a sunburst pattern.
