Seiko

Seiko's meca-quartz hybrid chronograph module combining quartz timekeeping accuracy with a mechanical chronograph module for a sweeping chronograph seconds hand. The VK63 features a date display at 4 o'clock and provides the satisfying mechanical pusher feel of a traditional chronograph at a fraction of the cost. Battery powered with approximately 3 years of life, it has become the movement of choice for affordable quartz chronographs.
