Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz motion movements, both created by Seiko, are frequently found in their watches, yet subtle distinctions exist. The PC21J is generally considered the earlier type, featuring a typical three-hand display – hours, minutes, and seconds. Its reliability is generally within ±15 seconds per duration. In comparison, the PC21S represents a later iteration, most notably known for its ability to display date information. This feature adds intricacy to the movement and can slightly impact its overall power. While these movements share a comparable architecture and operate on the same fundamental principles, the PC21S's date feature results in a slightly increased parts total and potentially a marginally smaller battery duration.
