Seiko TMI-VD57

The TMI-VD57 is a quartz chronograph movement manufactured in Japan by Seiko. Introduced in 2010, it features a tri-compax subdial layout with the chronograph seconds hand positioned in the 6:00 subdial rather than at the center—a distinctive arrangement that allows the central hand to function as a standard continuous seconds hand. The movement uses an SR920SW battery. It remains in production and is used across Seiko's chronograph collections.
