Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz mechanism movements, both manufactured by Seiko, are frequently found in their watches, yet subtle differences exist. The PC21J is generally considered the earlier model, 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 later iteration, most notably known for its ability to show date information. This feature adds intricacy to the movement and can slightly change its overall consumption. While the two movements share a comparable architecture and work on the same fundamental principles, the PC21S's date feature results in a slightly increased parts count and potentially a marginally smaller battery time.
