トダウンになる効果を有するものである。As described above, according to the present invention, a watch exterior component composition contains 10 to 40 weight fan% of a crystalline thermoplastic resin, 0.1 to 5 parts of a high carbon acid metal lead lubricant/resin, and a fibrous inorganic material. Mechanical strength is improved by creating a composition containing 5-40% by weight, 50-70% by weight of one or more spherical metal powders, and 0.1-5 parts by weight of a silane thread surface treatment agent/metal powder. The molded surface is slightly rougher than those using heavy metal powder, but the surface roughness is much better than that of amorphous metal powder. In particular, since the heavy metal tungsten is not used, it has the effect of greatly reducing costs.
