The timepiece component of the present invention is characterized by having an amorphous alloy film on the surface. Amorphous alloys do not have grain boundaries and have a high hardness, so the friction coefficient is low. Therefore, it is hard to wear. INDUSTRIAL APPLICABILITY The present invention is effective for timepiece parts, particularly gear parts and bearings, which are always exposed to friction and easily worn. Iron (Fe), cobalt (Co), nickel (Ni) or zirconium (Zr) is applied to the surface of these parts.

Table 1 shows the results of the abrasion resistance evaluation of Comparative Example 1. The abrasion resistance was evaluated as follows. That is, the analog quartz timepiece was driven by acceleration for 3 years in a non-lubricated state, the change in the starting voltage of the step motor after driving was measured, and the state of wear was visually evaluated. The initial value of the starting voltage was 1.60 V, and if the rate of change was 1% or less, it was determined that the wear resistance was good.

てしまった。It can be seen from Table 1 that in all of Examples 1 to 4 in which the fifth gear pinion, which is the embodiment of the timepiece component of the present invention, is coated with the amorphous alloy film, the wear resistance is dramatically improved. . That is, even in the oil-free state, the starting voltage was hardly changed after three years of acceleration driving, and no wear was observed on the appearance. In the present invention, the No. 5 gear pinion, which is exposed to the most severe wear, was evaluated, but the same effect is expected in other timepiece parts. On the other hand, in the comparative example, the fifth gear pinion was greatly worn and a large amount of wear debris was produced, and the acceleration drive for 3 years could not be performed, and it stopped after 4 months.
