摘要： A timepiece part according to the invention includes: a substrate; and a first coating configured from a material containing cobalt as a primary component, and 26 mass% to 30 mass% of Cr, and 5 mass% to 7 mass% of Mo. The first coating has a surface with a percentage surface area increase of 0% to 1.2% as measured by atomic force microscopy against a reference flat surface.

摘要： Provided are a timepiece part having an outstanding appearance, outstanding corrosion resistance, and outstanding scuff resistance and wear resistance; and a timepiece having the timepiece part. The timepiece part has a substrate; and a first coating made from a material containing Co and including greater than or equal to 26 wt% and less than or equal to 30 wt% Cr, and greater than or equal to 5 wt% and less than or equal to 7 wt% Mo. The substrate is preferably made from a material including at least one of stainless steel and Ti. A second coating made of a material including at least one of TiC and TiCN is preferably disposed between the substrate and first coating.

摘要： A timepiece part includes: a substrate; and a first coating configured from a material containing cobalt as a primary component, and 26 mass% to 30 mass% of Cr, and 5 mass% to 7 mass% of Mo. The first coating has an average signal intensity of oxygen of 0 counts/sec to 150 counts/sec as measured by SIMS relative to a 1.0 µm-thick reference film of a composition containing Co: 62.8 mass%, Cr: 28.2 mass%, Mo: 6.0 mass%, C: 1.5 mass%, and Ar: 1.5 mass%.
