The Seiko 7025 caliber, introduced in the late 1960s, is a 17-jewel automatic movement that powered a range of Seiko 5 and dress watches during the 1970s. Operating at 21,600 beats per hour, it features a quickset date function and a bidirectional winding system with a "frog leg" rotor design, allowing efficient energy transfer regardless of rotor direction. With a diameter of 27mm and a height of 5.3mm, the 7025 is a durable workhorse, equipped with Seiko’s Diashock shock protection for enhanced resilience. While it lacks hacking seconds and manual winding capabilities, its robust construction and ease of maintenance have made it a favorite among vintage watch enthusiasts. The movement’s design laid the groundwork for later calibers, such as the 7S26, reflecting Seiko’s evolutionary approach to watchmaking. Its reliability is evidenced by stories of unserviced examples running accurately for decades, as noted in collector discussions, making it a cornerstone of Seiko’s vintage legacy.
