We have had many calls for larger snap-on nylon dies to fit our CRY-905.00. This set is designed for larger oversized watches that are very popular, and most have snap-on case backs. There are a total of six pieces, three flat on both sides: 35, 40 and 45mm, and three double sided concave that are 40/42.5, 45/47.5 and 50/52.5mm concave.
