- About this watch: The Seiko 7A28 is significant as the world’s first analog quartz chronograph, introduced in 1983 by Seiko. Unlike earlier quartz watches, it used fully mechanical-style gear trains to drive multiple hands, delivering precise chronograph functionality without stepping motors for each register. This innovation combined quartz accuracy with traditional watchmaking architecture, influencing future hybrid designs. The 7A28 also gained cultural relevance through its use in military-issued models and its appearance on Ellen Ripley in Aliens, cementing its legacy among collectors.
