发明名称 ANTI-MAGNETISM STRUCTURE OF CLOCK
摘要 PROBLEM TO BE SOLVED: To improve the anti-magnetic property of a clock. SOLUTION: For an amorphous material 16 provided between a rear cover 12 and a movement 13 and between a dial 14 and the movement 13, a plurality of discoidal amorphous materials are laminated. An amorphous material 17 being provided around the side-surface side of the movement 13 has structure where a long tape-shaped amorphous material is wound spirally for laminating. The composition of the amorphous material 16 and 17 is 67.0 Fe-18.0 Co-14.0 B-1.0 Si (wt.%). The amorphous material being provided around the side-surface side of the movement 13 may have structure where a plurality of circular amorphous materials are concentrically laminated.
