An electronic timepiece includes a first display section including a first rotatable part and a processor. In the first display section, a predetermined number of display contents being a same display content is simultaneously displayed at predetermined angle intervals in a rotation angle range of the first rotatable part, wherein the predetermined number is two or more. The first display section makes a display pattern that shows change in the display content appear the predetermined number of times cyclically according to rotation of the first rotatable part. When causing the first display section to display a first display content of first display contents included in the display pattern, the processor selects an angular position from angular positions for the first display content in the predetermined number of display patterns, and causes the first rotatable part to rotate to the selected angular position.
