A timepiece button structure has a base having a first cavity, a first button member, a second button member having a second cavity part, first and second urging members, and first and second movement-limiting members. The second button member is disposed to protrude from and recede into the first cavity part with the second urging member urging the second button member in the direction protruding from the first cavity part and the second movement-limiting member limiting movement in the protrusion direction. The first button member is disposed to protrude from and recede into the second cavity part with the first urging member urging the first button member in the direction protruding from the second cavity part and the first movement-limiting member limiting movement in the protrusion direction. The first button member moves alone in the receding direction until the first button member contacts the second button member when the first button member is pushed against the urging force of the first urging member in the direction receding into the second cavity part, and the first and second button members move together in the receding direction when the first button member is pushed further against the urging force of the first and second urging members in the direction receding into the first cavity part after the first button member contacts the second button member.
