PROBLEM TO BE SOLVED: To provide a watch with a case (12) having a shell (14), a crystal (16), an indicating dial (18). SOLUTION: The crystal (16) contacts a shell (14) and includes a collar (36) in an outside radial direction that retains by contacting in an axis direction or by contacting the shell (14) by a glass rim (20). The glass rim (20) includes a surface (44) in a downward annular raidal direction that contacts the upper surface (46) of the collar (36) in the axis direction. According to one of the features, the collar (36) includes a convex periphery surface (52) that is complementary against the concave inside surface 54 of glass rim (20) arranged facing under a contact surface (44) in the radial direction of the glass rim (20) and also, contacts the inside surface (54) in the radial direction when an impact in the axis direction is applied to the crystal (16).
