Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz system movements, both produced by Seiko, are frequently found in their watches, yet subtle distinctions exist. The PC21J is generally considered the earlier version, featuring a standard three-hand display – hours, minutes, and seconds. Its accuracy is generally within ±15 seconds per duration. In contrast, the PC21S represents a updated iteration, most notably known for its ability to display date information. This functionality adds complexity to the movement and can slightly affect its overall consumption. While both movements share a similar architecture and work on the same fundamental principles, the PC21S's date complication results in a slightly increased parts total and potentially a marginally reduced battery duration.
