History & Legacy of Gruen

Founded in 1874, Gruen became one of America’s most important watchmakers, blending Swiss movement manufacture with U.S. design and distribution. The company’s Precision line represented its commitment to dependable, everyday timekeeping. Autowind models with bumper mechanisms—like the Caliber 460SS—capture a pivotal era when automatic wristwatches were evolving from novelty to mainstream reliability.

This Gruen Precision Autowind pairs a practical military/field dial with the characterful feel of a bumper automatic and the distinctive Guildite case finish. Fresh from service, it’s an excellent choice for collectors seeking a wearable slice of mid-century watch history.
