At its heart lies the Seiko 5126A automatic movement, operating at 19,800 beats per hour. This 23-jewel movement includes a day-date complication, with the date quickset function activated by pressing the crown. Notably, it lacks hand-winding and hacking features, which were more common in higher-end models of the time. The movement's architecture is distinctive, utilizing reverser wheels for the automatic winding mechanism, differing from Seiko's typical pawl and transmission wheel system.

It runs strong with vary good accuracy.
