Marathon Watch Company ETA High-Torque Quartz

The ETA High-Torque Quartz is a quartz movement manufactured by Marathon Watch Company. It delivers high torque output specifically engineered for marathon's dive instruments, providing the increased power needed to drive larger hands required in professional diving applications. The movement powers the JSAR (Jumbo Search and Rescue) quartz diver, a model designed for military and search-and-rescue operations. It remains in production and is used exclusively in Marathon's professional-grade dive watches.
