Arita Porcelain Dial
See-through & Screw case back
*This Arita porcelain dial is created through handwork and firing at a high temperature. As a result, it may have little dimples, tiny dots, and an uneven color. These are unique features of genuine Arita porcelain dials, of which no two are exactly alike.
