What distinguishes it
Look beyond the reference.
Adding the weekday creates a more informative everyday calendar display. At 5.05 mm, this movement is taller than the date-only SW200-1, despite sharing the family’s 4 Hz rhythm.
For the enthusiast
These figures describe the SW220-1 in Sellita’s published catalogue, not a later Power+ derivative. The exact day-disc language and calendar position belong to the watch’s execution. When comparing watches, look at the display you actually want as well as the movement name.
