Electronic timepiece with internal antenna

An electronic timepiece with internal antenna, comprising:

• a cylindrical external case;
• a crystal that covers one of the two openings of the external case;
• a drive mechanism that drives a hand inside the external case;
• an antenna that has a cylindrical side part made of metal, a metal bottom part that covers one of the two openings of the side part, and a metal top part that extends transversely to the center axis of the side part inside the external case, and contacts the inside surface of the side part,
• holds the drive mechanism between the bottom part and the top part, and has the top part disposed between the drive mechanism and the crystal;
• and
• an annular dielectric that extends circumferentially to the side part and contacts the top part in the axial direction of the side part;
• wherein the external case has a metal part that is made of metal,
• the bottom part is a back cover that covers the other of the two openings of the external case,
• the top part has a slot part that extends circumferentially to the side part and contacts the dielectric,
• a slot that extends circumferentially to the side part is formed in the slot part, and
• the dielectric covers part or all of the slot in the axial direction of the side part.
