Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz motion movements, both manufactured by Seiko, are frequently seen in their watches, yet subtle distinctions exist. The PC21J is generally considered the earlier model, featuring a standard three-hand display – hours, minutes, and seconds. Its precision is generally within ±15 seconds per period. In comparison, the PC21S represents a updated iteration, most notably known for its ability to show date information. This functionality adds sophistication to the movement and can slightly impact its overall consumption. While both movements share a akin architecture and function on the same fundamental principles, the PC21S's date feature results in a slightly higher parts total and potentially a marginally smaller battery duration.
