The center medallion is 3" north to south X 2 1/4". Both that and the other stations are curved to fit around the wrist well. Look at the decades of rich dark patina in the numerous crevices of the 1/2 lotus yoga position sitting Indian lady. The 2 stations on either side are just under 1 1/2" north to south. PS, while the end piece looks odd and out of place...please view last image to see how it does make sense.
