A watch component includes an austenized ferritic stainless steel, the austenized ferritic stainless steel including a first layer including a ferrite phase, and a second layer including an austenized phase formed of a nitrogen solid solution of the ferrite phase. An average particle size of ferrite crystal grains constituting the ferrite phase is 300 μm or greater, and an average particle size of austenitic crystal grains constituting the austenized phase is 150 μm or smaller.
