Radio controlled timepiece and method for controlling radio controlled timepiece

A radio controlled timepiece comprising:

• a reception section that receives a standard radio wave;
• a reference signal source that produces a reference signal;
• a time measurement section that measures internal time based on the reference signal;
• a reception control section that causes the reception section to operate and carries out a reception process;
• and
• a time correction section that corrects the internal time,
• wherein the reception control section
• carries out the reception process at first time to acquire first reception time data,
• compares the acquired first reception time data with the internal time, and
• carries out the reception process at second time different from the first time to acquire second reception time data when a difference in time between the first reception time data and the internal time is greater than or equal to a preset first threshold, and
• the time correction section
• compares the acquired second reception time data with the internal time, and
• corrects the internal time based on the second reception time data when a difference in time between the second reception time data and the internal time is smaller than a preset second threshold.
