To provide a portable timepiece in which there has been made such that a constitution for removing, together with a winding stem, a crown from a timepiece movement does not become a restriction factor in regard to a size of a dial, and a factor impairing a design visually showing a periphery part of a timepiece armor assembly thinly. A timepiece movement is built-in in a timepiece armor assembly which possesses an armor case of one-piece structure in which a case bottom wall and a case barrel part have been monolithically made, and in which a taper face has been formed in a peripheral part back face of the case. A winding stem having a stopper engagement part and connected to a movement so as to be insertable/removable from a side is built-in in the armor assembly so as to be movable in a direction intersecting a thickness direction of this assembly. A crown connected to the winding stem is made detachable in the barrel part from a side. A stopper member capable of engaging with and disengaging from the engagement part is built-in in the armor assembly. There is possessed an engagement/disengagement operation body which moves in the direction intersecting the thickness direction of the armor assembly to thereby interlock the member, and which causes the member to engage with and disengage from the engagement part, and this operation body is provided in the case barrel part so as to be operable from a side of the case barrel part.
