Metal case ring is made to hold the movement into the case. The outside diameter is 35.5mm with a height of 5mm fit perfectly with the NH35 watch movement in our Make My Own Watch Kit. There is a slot cutout for the stem and case tube. Movement rings are an important part of a building a watch so the movement doesn't jostle around and get damaged inside the case.
