Comparing PC21J and PC21S Quartz Movements
The PC21J and PC21S quartz system movements, both created by Seiko, are frequently seen in their watches, yet subtle differences exist. The PC21J is generally considered the earlier type, featuring a typical three-hand display – hours, minutes, and seconds. Its accuracy is generally within ±15 seconds per period. In contrast, the PC21S represents a later iteration, most notably known for its ability to present date information. This capability adds complexity to the movement and can slightly impact its overall consumption. While the two movements share a similar architecture and function on the same fundamental principles, the PC21S's date complication results in a slightly greater parts total and potentially a marginally lesser battery duration.
