Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz motion movements, both created by Seiko, are frequently encountered in their watches, yet subtle differences exist. The PC21J is generally considered the earlier model, featuring a common three-hand display – hours, minutes, and seconds. Its accuracy is generally within ±15 seconds per period. In comparison, the PC21S represents a later iteration, most notably known for its ability to present date information. This functionality adds complexity to the movement and can slightly affect its overall power. While these movements share a comparable architecture and operate on the same fundamental principles, the PC21S's date addition results in a slightly higher parts number and potentially a marginally smaller battery duration.
