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 variations exist. The PC21J is generally considered the earlier type, featuring a standard three-hand display – hours, minutes, and seconds. Its reliability is generally within ±15 seconds per month. In contrast, the PC21S represents a subsequent iteration, most notably known for its ability to show date information. This functionality adds intricacy to the movement and can slightly impact its overall energy. While these movements share a comparable architecture and work on the same fundamental principles, the PC21S's date addition results in a slightly increased parts count and potentially a marginally reduced battery duration.
