Introduced in the late 1970s, these models offered enhanced functionality, including higher-beat movements for improved timekeeping and a quick-set date mechanism. They retain the classic 36mm case proportions of their predecessors while offering a wide variety of dial, bezel, and bracelet configurations. Luminous models also retain tritium, allowing for the development of distinctive and highly individual patina over time. The present example features an era-appropriate onyx 'Sigma'dial and is accompanied by a service receipt documenting the factory dial replacement in May 1996. The combination of its minimalist aesthetic and period documentation makes it an especially appealing example for collectors.
