The Sixties Square Chronograph first came out in 2009, offering a fresh interpretation of the 1960's aesthetic. In 2017, Glashütte Original expanded the collection with unique dials in vibrant colors and textures, inspired by the round Sixties models from the past. One standout is Reference 1-39-34-26-32-04, featuring a stunning tangerine dial with a gradient effect and a sunburst pattern. It's a perfect blend of retro charm and modern flair.
