The Atlantic brand was founded in 1888 in Lengnau, Switzerland, and for many years became a symbol of "durability and elegance," particularly in Central and Eastern Europe. In the 1950s and 1960s, the Worldmaster series rose to prominence as one of the brand's most recognizable models. The term "Superextra" was used at the time to designate models with higher-quality movements, exclusive settings, and superior material workmanship. This model is a classic Swiss watch with a simple yet powerful design. Its slim case, domed glass, and elegant dial represent both the aesthetics of its time and the golden age of mechanical watchmaking. The Worldmaster Superextra boasts a durable movement that has continued to function for over 60 years—a testament to its status as not just a timepiece but also a legacy of Swiss engineering. For collectors, this watch is a rare piece with both nostalgic value and reliable mechanical character. Its classic style makes it an elegant addition to everyday wear.
