Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz system movements, both produced by Seiko, are frequently encountered in their watches, yet subtle differences exist. The PC21J is generally considered the earlier type, featuring a common three-hand display – hours, minutes, and seconds. Its precision is generally within ±15 seconds per period. In comparison, the PC21S represents a later iteration, most notably known for its ability to display date information. This functionality adds sophistication to the movement and can slightly impact its overall power. While the two movements share a akin architecture and operate on the same fundamental principles, the PC21S's date feature results in a slightly increased parts number and potentially a marginally reduced battery time.
