Seiko 8T67

Seiko caliber 8T67 is a mecaquartz chronograph movement made in Japan. It combines a quartz timebase with a mechanical chronograph module, giving it the accuracy of quartz with the tactile feel of a mechanical stopwatch. The movement has zero jewels and the stopwatch hand advances in 1/5 second increments. It uses the vertical 12-6-9 subdial layout and is the Seiko-branded version of the TMI VK67.
