Story & Heritage Atlantic is a historic Swiss watchmaker known for producing robust and practical mechanical watches with distinctive styling. The Worldmaster became one of the company’s best-recognized lines, combining reliable Swiss movements with excellent legibility and a strong everyday character. During the 1950s, contrasting bull’s-eye dials were valued not only for their visual appeal but also for their functionality. The concentric colour arrangement naturally directed the eye toward the hour markers and hands, allowing the time to be read quickly and clearly. This design language was closely associated with military, travel and sporting watches of the period. This example preserves that character beautifully. Its original silver and blue dial has developed a rich natural patina that records more than seven decades of history, while the 21-jewel mechanical movement and Incabloc shock protection reflect the practical engineering expected from a quality Swiss wristwatch. At approximately 36 mm, the case was generously proportioned for its era and remains extremely wearable today. With its unusual two-tone dial, red seconds hand and authentic signs of age, this Atlantic Worldmaster is not simply a vintage watch—it is a wonderfully expressive survivor from the golden age of Swiss mechanical watchmaking.
